1. 09 Series System Configuration(s)

The 09 Series Stabilized Antenna system is to be used for Transmit/Receive (TX/RX) satellite communications, it is comprised of
two major groups of equipment. These are the Above Decks Equipment (ADE) and the Below Decks Equipment (BDE). There
will also be interconnecting cables between the ADE & BDE and cables to provide other inputs to the system.

1.1. Series 09 Basic System Information

Series 09 Antennas will be available in 3 dish sizes (Diameter – active area):
• 1.0 M (40 inch)
• 1.2 M (50.0 inch)
• 1.5 M (60 inch)
Each dish size will be available in multiple configurations:
• Variety of BUC manufacturers and power output capabilities
• Variety of BUC/HPA power output capabilities
• Cross-Pol Feed assembly
• Optional Co-Pol diplexer and LNB
• Choice of Single fixed frequency, dual-band, tri-band or Quad-Band LNB(s)
The Series 09 antennas are available in multiple tuned radome sizes:

AC Power & Coaxial cables will be discussed in a separate chapter.

1.3. Other Inputs to the System

Multi-conductor cables from Ships Gyro Compass, GPS, phone, fax and Computer equipment may also be connected
in the system.

1.4. Simplified block diagram of a Series 09 system

Your Series 09 TXRX system consists of two major groups of equipment; an above-decks group and a below-decks
group. Each group is comprised of, but is not limited to, the items listed below. All equipment comprising the Above
Decks is incorporated inside the radome assembly and is integrated into a single operational entity. For inputs, this
system requires only an unobstructed line-of-sight view to the satellite, Gyro Compass input and AC electrical power.

• Customer Furnished Equipment - Satellite Modem and other below decks equipment required for the
desired communications purposes (including LAN and VOIP equipment).
• Appropriate Coax, Ethernet, and telephone cables

1.5. Dual Antenna Configuration

Sometimes, due to very large blockage conditions, you may need to install a dual antenna configuration to provide
uninterrupted services. Two full antenna systems are installed and the ACU control outputs are connected to an
arbitrator switch panel which then is connected to the below decks equipment. NOTE: The RXIF from EACH antenna
MUST be connected to the RF IN (J6) on the rear panel of its respective ACU then RFOUT (J7) is connected to the RXIF
input of the Dual Antenna Arbitrator. This connection scheme is required for ACU “A” to be able to control Antenna
“A” (and ONLY Antenna “A”) AND ACU “B” to be able to control Antenna “B” (and ONLY Antenna “B”).
You will program the blockage zone(s) for each of the two antennas (refer to Setup – Blockage Zones). The blockage
output from the ACU is fed to the Terminal Mounting Strip so that the output of each ACU can be connected to the
arbitrator panel to control it. The blockage output is available on SW2 terminal of the Terminal Mounting Strip to
provide a transistor “short” to ground when the antenna is within a blockage zone programmed into the ACU. When
not blocked the SW2 terminal will be an “open”.
When one antenna is blocked, its blockage output will command the arbitrator panel to switch services to the modem
from that antenna to the other antenna. The arbitrator panel provides a logic latch to prevent excess switching when
the ship heading is yawing, therefore, causing if the antenna to be repeatedly blocked – unblocked – blocked.

1.6. Dual Antenna Arbitrator

The Dual Antenna Arbitrator panel can pass LNB voltages (and handle 250-400 ma of current) and the RXIF signals on
the RX connections. TXIF, Reference and BUC supply voltage can be passed through this arbitrator panel to the
antenna, but it is not recommended that BUC power be supplied through the dual channel rotary joint of the antenna
(a BUC power supply is provided on all Series 09 Antenna Pedestals).
The blockage (SW2) output, GPS output and Modem lock input from the two terminal mounting strips (antenna “A”
and antenna “B”) are wired through the arbitrator panel to the satellite modem. When antenna “A” is blocked, the
arbitrator PCB will toggle the coax switches so that antenna “B” provides signal to the BDE distribution (multi-switch or
modem). When antenna “A” is no longer blocked the arbitrator will do nothing (because it is a latch circuit). When
antenna “B” is blocked the panel will switch so that antenna “A” is again providing signal the BDE distribution.
To provide a seamless switching transition, refer to the arbitrator installation instructions to balance the TX & RX signal
levels between the two antennas.

1.7. Open Antenna-Modem Interface Protocol (OpenAMIP™) Specification:

1.7.1. Overview:
OpenAMIP, an ASCII message based protocol invented and Trademarked by iDirect is a specification for the
interchange of information between an antenna controller and a satellite modem. This protocol allows the
satellite modem to command the ACU (via TCP port 2002) to seek a particular satellite as well as allowing
exchange of information necessary to permit the modem to initiate and maintain communication via the
antenna and the satellite. In general, OpenAMIP is not intended for any purpose except to permit a modem
and the ACU to perform synchronized automatic beam switching. It is NOT a status logging system or a
diagnostic system. In addition, OpenAMIP is intend for a typical installation whereby a specific satellite
modem and Antenna system are properly configured to work together. The protocol does not make specific
provisions for auto-discovery or parameter negotiation. It is still the responsibility of the installer to assure
the parameters of both the satellite modem (proper option files) and the ACU/PCU (setup parameters) are

Site Survey 5009-17 Installation Manual

2. Site Survey
The objective of the Site survey is to find the best place to mount the antenna & the below decks equipment, the length and
routing of the cables and any other items or materials that are required to install the system and identify any other issues that
must be resolved before or during the installation. For Naval Engineering level information on this subject, please refer
to Antenna Installation Guideline – Site Arrangement, document number 130040_A available on the Sea Tel
Dealer Support Site.

2.1. Site Selection Aboard Ship

The radome assembly should be installed at a location aboard ship where:
• The antenna has a clear line-of-sight to view as much of the sky (horizon to zenith at all bearings) as is
practical.
• X-Band (3cm) Navigational Radars:
• The ADE should be mounted more than 0.6 meters/2 feet from 2kW (24 km) radars
• The ADE should be mounted more than 2 meters/8 feet from 10kW (72 km) radars
• The ADE should be mounted more than 4 meters/12 feet from 160kW (250km) radars
• S-Band (10cm) Navigational Radars:
• If the ADE is/has C-Band it should be mounted more than 4 meters/12 feet from the S-band Radar.
• The ADE should not be mounted on the same plane as the ship's Radar, so that it is not directly in the Radar
beam path.
• The ADE should be mounted more than 2.5 meters/8 feet from any high power MF/HF antennas (<400W).
• The ADE should be mounted more than 4 meters/12 feet from any high power MF/HF antennas (1000W).
• The ADE should also be mounted more than 4 meters/12 feet from any short range (VHF/UHF) antennae.
• The ADE should be mounted more than 2.5 meters/8 feet away from any L-band satellite antenna.
• The ADE should be mounted more than 3 meters/10 feet away from any magnetic compass installations.
• The ADE should be mounted more than 2.5 meters/8 feet away from any GPS receiver antennae.
• Another consideration for any satellite antenna mounting is multi-path signals (reflection of the satellite
signal off of nearby surfaces arriving out of phase with the direct signal from the satellite) to the antenna.
This is particularly a problem for the onboard GPS, and/or the GPS based Satellite Compass.
• The Above Decks Equipment (ADE) and the Below Decks Equipment (BDE) should be positioned as close to
one another as possible. This is necessary to reduce the losses associated with long cable runs.
• This mounting platform must also be robust enough to withstand the forces exerted by full rated wind load
on the radome.
• The mounting location is robust enough that it will not flex or sway in ships motion and be sufficiently well
re-enforced to prevent flex and vibration forces from being exerted on the antenna and radome.
• If the radome is to be mounted on a raised pedestal, it MUST have adequate size, wall thickness and gussets
to prevent flexing or swaying in ships motion. In simple terms it must be robust.
If these conditions cannot be entirely satisfied, the site selection will inevitably be a “best” compromise between the
various considerations.

2.2. Antenna Shadowing (Blockage) and RF Interference

At the transmission frequencies of C and Ku band satellite antenna systems, any substantial structures in the way of
the beam path will cause significant degradation of the signal. Care should be taken to locate the ADE so that the ADE
has direct line-of-sight with the satellite without any structures in the beam path through the full 360 degree ships
turn. Wire rope stays, lifelines, small diameter handrails and other accessories may pass through the beam path in
limited numbers; however, even these relatively insignificant shadows can produce measurable signal loss at these
frequencies.

2.3. Mounting Foundation

2.3.1. Mounting on Deck or Deckhouse

While mounting the ADE on a mast is a common solution to elevate the ADE far enough above the various
obstructions which create signal blockages, sometimes the best mounting position is on a deck or deckhouse
top. These installations are inherently stiffer than a mast installation, if for no other reason than the design of
the deck/deckhouse structure is prescribed by the ship’s classification society. In the deck/deckhouse design
rules, the minimum plating and stiffener guidelines are chosen to preclude high local vibration amplitudes.
Most installations onto a deck or deckhouse structure will require a mounting pedestal to raise the ADE above
the deck for radome hatch access and to allow the full range of elevation (see ADE mounting considerations
above). Some care must be taken to ensure the mounting pedestal is properly aligned with the stiffeners
under the deck plating.

2.3.2. ADE Mounting Considerations

Mounting the radome directly on the deck, or platform
prevents access to the hatch in the base of the radome
unless an opening is designed into the mounting surface to
allow such entry. If there is no access to the hatch the only
way to service the antenna is to remove the radome top.
Two people are required to take the top off of the radome
without cracking or losing control of it, but even with two
people a gust of wind may cause them to lose control and
the radome top may be catastrophically damaged (see
repair information in the radome specifications).
If access to the hatch cannot be provided in the mounting
surface, provide a short ADE support pedestal to mount the
ADE on which is tall enough to allow access into the radome
via the hatch.
Ladder rungs must be provided on all mounting stanchions
greater than 3-4 feet tall to allow footing for personnel
safety when entering the hatch of the radome.
The recommended cable passage in the 50, 60 and 66 inch
radomes is through the bottom center of the radome base,
down through the ADE support pedestal, through the deck
and into the interior of the ship.

2.3.3. Sizing of the support pedestal

The following should be taken into account when choosing the height of a mounting support stand:
1. The height of the pedestal should be kept as short as possible, taking into account recommendations
given in other Sea Tel Guidelines.
2. The minimum height of the pedestal above a flat deck or platform to allow access into the radome
for maintenance should be 0.6 meters (24 inches).
3. The connection of the ADE mounting plate to the stanchion and the connection of the pedestal to
the ship should be properly braced with triangular gussets (see graphic above). Care should be taken
to align the pedestal gussets to the ship’s stiffeners as much as possible. Doublers or other
reinforcing plates should be considered to distribute the forces when under-deck stiffeners are
inadequate.
4. The diameter of the pedestal stanchion shall not be smaller than 100 millimeters (4 inches). Where
the ADE base diameter exceeds 1.5 meters (60 inches), additional stanchions (quantity greater than
3) should be placed rather than a single large stanchion.
5. Shear and bending should be taken into account in sizing the ADE mounting plate and associated
gussets.
6. Shear and bending must be taken into account when sizing the pedestal to ship connection.
7. All welding should be full penetration welds –V-groove welds with additional fillet welds – with
throats equivalent to the thickness of the thinnest base material.

2-2
Site Survey 5009-17 Installation Manual

8. For an ADE mounted greater than 0.6 meters (24 inches) above the ship’s structure, at least one (1)
foot rung should be added. Additional rungs should be added for every 0.3 meter (12 inches) of
pedestal height above the ship’s structure.
9. For an ADE mounted greater than 3 meters (9 feet) above the ship’s structure, a fully enclosing cage
should be included in way of the access ladder, starting 2.3 meters (7 feet) above the ship’s
structure.

2.4. Mounting Height

The higher up you mount the antenna above the pivot point of the ship the higher the tangential acceleration (g-
force) exerted on the antenna will be (see chart below).
When the g-force exerted on the antenna is light, antenna stabilization and overall performance will not be affected.
If the g-force exerted on the antenna is high enough (> 1 G), antenna stabilization and overall performance will be
affected.
If the g-force exerted on the antenna is excessive (1-2 Gs), the antenna will not maintain stabilization and may even
be physically damaged by the g-force.

2.5. Mast Configurations

Sea Tel recommends the ADE be mounted on the ship in a location which has both a clear line-of-sight to the target
satellites in all potential azimuth/elevation ranges and sufficient support against vibration excitement. If possible,
mounting the ADE pedestal directly to ship deckhouse structures or other box stiffened structures is preferred.
However, in many cases, this imposes limits on the clear line-of-sight the antenna system has.
Often the solution for providing the full azimuth/elevation range the antenna needs is to mount the ADE on the ship’s
mast. Unfortunately, masts do not consider equipment masses in design and often have harmonic frequencies of their
own.
There are many designs of masts used on ships – masts are nearly as unique in design as the ship is – but the designs
often fall into just a few categories. These categories can be addressed in terms of typical responses and problems
with regards to vibration and mounting of ADE. The most common categories of masts are:

2-3
5009-17 Installation Manual Site Survey

2.5.1. Vertical Masts

Vertical masts are a very ancient and common mast design. In essence, it is the mast derived from the sailing
mast, adapted for mounting the ever-increasing array of antennae ships need to communicate with the
world. This drawing of a Vertical mast shows
preferred mounting of the ADE center-line above
the plane of the radar, or as an alternate with the
ADE mounted below the plane of the radar signal,
as reasonably good installations of a satellite
antenna ADE.
Vertical masts are most commonly still found on
cargo ships – they are simple, inelegant and
functional. They are also fairly stiff against
torsional reaction and lateral vibrations, as long as
the ADE is mounted on a stiff pedestal near the
vertical centerline of the mast. If centerline
mounting is impractical or otherwise prohibited,
the mast platform the ADE is mounted on should be checked for torsional vibration about the centerline of
the mast and the orthogonal centerline of the platform.
If the estimated natural frequency of the mast or platform is less than 35 Hertz, the mast or platform should
be stiffened by the addition of deeper gussets under the platform or behind the mast.

2.5.2. Raked Masts

Raked masts are found on vessels where the style
or appearance of the entire vessel is important.
Again, the inclined mast is a direct descendant from
the masts of sailing ships – as ship owners wanted
their vessels to look more unique and less
utilitarian, they ‘raked’ the masts aft to make the
vessel appear capable of speed. This drawing
shows a raked mast, again with the preferred ADE
mounting above the radar and alternate with the
ADE below the radar.
Raked masts pose special problems in both
evaluating the mast for stiffness and mounting of
antennae. As can be seen in the drawing all
antennae must be mounted on platforms or other
horizontal structures in order to maintain the
vertical orientation of the antenna centerline. This
implies a secondary member which has a different
natural frequency than the raked mast natural frequency. In order to reduce the mass of these platforms,
they tend to be less stiff than the main box structure of the raked mast. Thus, they will have lower natural
frequencies than the raked mast itself. Unfortunately, the vibratory forces will act through the stiff structure
of the raked mast and excite these lighter platforms, to the detriment of the antenna.

2.5.3. Girder Masts

Girder masts are large platforms atop a pair of
columns. Just like girder constructions in buildings,
they are relatively stiff athwart ship – in their
primary axis – but less stiff longitudinally and
torsionally. An example of a girder mast is shown in
this drawing, with the preferred ADE mounting
outboard and above the radar directly on one of the
columns and alternate with the ADE centered on
the girder above the plane of the radar.
The greatest weakness of girder masts is in torsion –
where the girder beam twists about its vertical
centerline axis. As with all mast designs discussed so far, mounting the antenna in line with the vertical
2-4
Site Survey 5009-17 Installation Manual

support structure will reduce the vibration tendencies. Mounting the antenna directly above the girder
columns provides ample support to the antenna pedestal and locates the antenna weight where it will
influence the natural frequency of the mast the least.

2.5.4. Truss Mast

Truss masts are a variant on the girder mast
concept. Rather than a pair of columns supporting a
girder beam, the construction is a framework of
tubular members supporting a platform on which
the antennae and other equipment is mounted. A
typical truss mast is shown in this photograph.
Like a girder mast, truss masts are especially stiff in
the athwart ship direction. Unlike a girder mast, the
truss can be made to be nearly as stiff in the
longitudinal direction. Truss masts are particularly
difficult to estimate the natural frequency – since a
correct modeling includes both the truss structure
of the supports and the plate/diaphragm structure
of the platform. In general, though, the following
guidelines apply when determining the adequate
support for mounting an antenna on a truss mast:
1. Antenna ADE pedestal gussets should align
with platform stiffeners which are at least
200 millimeters in depth and 10 millimeters in thickness.
2. When possible, the antenna ADE pedestal column should align with a vertical truss support.
3. For every 100 Kilograms of ADE weight over 250 Kilograms, the depth of the platform stiffeners
should be increased by 50 millimeters and thickness by 2 millimeters.
Sea Tel does not have a recommended arrangement for a truss mast – the variability of truss mast designs
means that each installation needs to be evaluated separately.

2.6. Safe Access to the ADE

Safe access to the ADE should be provided. Provisions of the ship’s Safety Management System with regard to men
aloft should be reviewed and agreed with all personnel prior to the installation. Installations greater than 3 meters
above the deck (or where the access starts at a deck less than 1 meter in width) without cages around the access
ladder shall be provided with means to latch a safety harness to a fixed horizontal bar or ring.
The access hatch for the ADE shall be oriented aft, or inboard, when practicable. In any case, the orientation of the
ADE access hatch shall comply with the SMS guidelines onboard the ship. Nets and other safety rigging under the ADE
during servicing should be rigged to catch falling tools, components or fasteners.

2.7. Below Decks Equipment Location

The Antenna Control Unit, Terminal Mounting Strip and Base Modem Panel are all standard 19” rack mount, therefore,
preferred installation of these items would be in such a rack. The ACU mounts from the front of the rack. The
Terminal Mounting Strip and Base Modem Panel mount on the rear of the rack.
The Satellite Modem, router, VIOP adapter(s), telephone equipment, fax machine, computers and any other associated
equipment should also be properly mounted for shipboard use.
Plans to allow access to the rear of the should be considered.

2.8. Cables
During the site survey, walk the path that the cables will be installed along. Pay particular attention to how cables will
be installed all along the path, what obstacles will have to have be routed around, difficulties that will be encountered
and the overall length of the cables. The ADE should be installed using good electrical practice. Sea Tel recommends
referring to IEC 60092-352 for specific guidance in choosing cables and installing cables onboard a ship. Within these
guidelines, Sea Tel will provide some very general information regarding the electrical installation.
In general, all cables shall be protected from chaffing and secured to a cableway. Cable runs on open deck or down a
mast shall be in metal conduit suitable for marine use. Cables passing through bulkheads or decks shall be routed
through approved weather tight glands.

2-5
5009-17 Installation Manual Site Survey

2.8.1. ADE/BDE Coaxial Cables

The first concern about the coaxial cables installed between the ADE & BDE is length. This length is used to
determine the loss of the various possible coax, Heliax or fiber-optic cables that might be used. You should
always provide the lowest loss cables to provide the strongest signal level into the satellite modem.
Signal cable shall be continuous from the connection within the ADE radome, through the structure of the
ship to the BDE. Splices, adapters or dummy connections will degrade the signal level and are discouraged.
Be careful of sharp bends that kink and damage the cable. Use a proper tubing bender for Heliax bends.
Penetrations in watertight bulkheads are very expensive, single cable, welded penetrations that must be
pressure tested.
Always use good quality connectors that are designed to fit properly on the cables you are using. Poor
quality connectors have higher loss, can allow noise into the cable , are easily damaged or fail prematurely.
In as much as is possible, don’t lay the coaxes on power cables. Try to have some separation from Inmarsat &
GPS cables that are also passing L-band frequencies or Radar cables that may inject pulse repetition noise –as
error bits - into your cables.

2.8.2. Antenna Power Cable

Be cautious of length of the run, for voltage loss issues, and assure that the gauge of the wires is adequate for
the current that is expected to be drawn (plus margin) . Antenna power is not required to be from a UPS
(same one that supplies power to the below decks equipment), but it is recommended.

2.8.3. Air Conditioner Power Cable

If your system includes a marine air conditioner (available with the 81 inch radome ONLY), run an AC power
cable to it from a breaker, preferably from a different phase of the electrical system than supplies power to
the ADE & BDE. Be EXTREMELY cautious of length of the run for voltage loss and gauge of the wires for the
current that is expected to be drawn.

2.8.4. ACU Power Cable/outlet

The AC power for the ACU and other below decks equipment is not required to be from a UPS (same one that
supplies power to the ADE), but it is recommended.

2.8.5. Gyro Compass Cable

Use good quality shielded cable (twisted pairs, individually foil wrapped, outer foil with braid overall is best)
You only need 2-wire for NMEA signal, 4-wire for Step-By-Step and 5-wire for Synchro … always use shielded
cable. Be cautious of length and gauge of the run for voltage loss issues.

2.9. Grounding
All metal parts of the ADE shall be grounded to bare metal at the mounting pedestal. Grounding straps from the base
of the ADE to a dedicated lug on the mounting pedestal are preferred, but grounding may also be accomplished by
exposing bare metal under all mounting bolts prior to final tightening. Preservation of the bare metal should be done
to prevent loss of ground.
Grounding should be ensured throughout the entire mounting to the hull. While it is presumed the deckhouse is
permanently bonded and grounded to the hull, in cases where the deckhouse and hull are of different materials a
check of an independent ground bonding strap should be made. Masts should be confirmed to be grounded to the
deckhouse or hull.

3. Installation
Your antenna pedestal comes completely assembled in its radome. This section contains instructions for unpacking, final
assembly and installation of the equipment. It is highly recommended that installation of the system be performed by trained
technicians.
Your antenna may have been ordered in any one of a variety of different diameter radomes. The installation instructions for
most common radome sizes for your system are below.

3.1. Unpacking and Inspection

Exercise caution when unpacking the equipment.
1. Unpack the crates. Carefully inspect the radome surface for evidence of shipping damage.
2. Unpack all the boxes.
3. Inspect everything to assure that all materials have been received and are in good condition.
3.2. Assembly Notes and Warnings

NOTE: Unless otherwise indicated, all nuts and bolts should be assembled with Loctite 271
or its equivalent

WARNING: Assure that all nut & bolt assemblies are tightened according to the
tightening torque values listed below:
SAE Bolt Size Inch Pounds Metric Bolt Size Kg-cm
1/4-20 75 M6 75.3
5/l6-18 132 M6 225
3/8-16 236 M12 622
1/2-13 517
WARNING: Hoisting with other than a webbed four-part sling may result in catastrophic
crushing of the radome. Refer to the specifications and drawings for the fully assembled
weight of your model Antenna/Radome and assure that equipment used to lift/hoist this
system is rated accordingly.

CAUTION: The antenna/radome assembly is very light for its size and is subject to large
swaying motions if hoisted under windy conditions. Always ensure that tag lines, attached
to the radome base frame, are attended while the antenna assembly is being hoisted to its
assigned location aboard ship.

3.3. Installing the ADE

The antenna pedestal is shipped completely assembled in its radome. Please refer to the entire Site Survey chapter of
this manual.
Base Hatch Access - Mounting the radome directly on the deck, or
platform prevents access to the hatch in the base of the radome unless an
opening is designed into the mounting surface to allow such entry. If there is
no access to the hatch the only way to service the antenna is to remove the
radome top. Two people are required to take the top off of the radome
without cracking or losing control of it, but even with two people a gust of
wind may cause them to lose control and the radome top may be
catastrophically damaged (see repair information in the radome
specifications) or lost.
If access to the hatch cannot be provided in the mounting surface, provide a
short ADE mounting stanchion to mount the ADE on which is tall enough to
allow access into the radome via the hatch.
Ladder rungs must be provided on all mounting stanchions greater than 3-4
feet tall to allow footing for personnel safety when entering the hatch of the
radome.
Cable Passage - The radome base is designed with a bottom center cable
passage and Roxtec® Multidiameter® blocks for cable strain relief. The
recommended cable passage in the 50, 60 and 66 inch radomes is through the
bottom center of the radome base, down through the ADE mounting
stanchion, through the deck and into the interior of the ship.
Bottom center cable passage is recommended, however, a strain relief kit is provided with the system if off-center
cable entry is required. Note: Strain relief installation procedure, provided in the Drawings chapter, MUST
be followed to assure that the cored holes are properly sealed to prevent moisture absorption and de-
lamination of the radome base.

3.3.1. Prepare the 50”, 60”, 66” or 76” Radome Assembly

1. Remove the side walls of the Radome crate.

2. Lift the pallet using a forklift and/or jacks.
3. From the under side of the pallet, remove the
4 shipping bolts which attach the ADE to its’
pallet. Discard this shipping hardware.

4. Remove four equally spaced bolts around the

radome flange. Save these nuts and bolts to
be re-installed later.
5. Install four lifting eyebolts in the vacant holes
in the flange of the radome.. (Hardware
provided in the radome installation kit). Keep
the original perimeter bolt hardware to be re-
installed after the ADE has been installed.

7. Remove the hardware in the cable mounting frame.

8. Lift the cable mounting frame out from the cable

passage channel.
NOTE: If the bottom center cable passage will NOT
be used, it is recommended that the strain reliefs be
installed in place of this cable mounting frame. Other
locations around the radome base are MUCH thicker,
requiring longer strain reliefs than the ones provided
by Sea Tel. Refer to the strain relief installation
procedure provided in the Drawings chapter of this
manual.
9. Man the tag line and have the crane continue lifting
the ADE up and hover above the mounting site on
the ship.
10. Carefully route AC Power and IF coax cables through
the cable passage in the bottom center of the
radome base and through the cable channel under
the lower base plate of antenna.
NOTE: Suitable strain relief should be provided below
the mounting surface to prevent the cables from
being kinked where the cables exit the bottom of the
radome.
11. Allow enough service loop to terminate these cables
to the circuit breaker assembly and connector
bracket respectively (see cable termination
information below).
HINT: It may be easier to connect, or tie-wrap, the
coaxes and power cable temporarily.
12. Lower radome assembly into the mounting holes,
positioned with the BOW reference of the radome as
close to parallel with centerline of the ship as
possible (any variation from actual alignment can be
electrically calibrated if needed).
13. Using Loctite 271, install the 4 fender washers and
hex nuts (provided in the radome installation kit),
from the underside of the mounting surface, to affix
the radome to the mounting surface. .
14. Remove the clamp bar and Roxtec® Multidiameter®
blocks from their cable mounting frame in the cable
passage channel.

3-4
Installation 5009-17 Installation Manual

15. Remove the rubber bar from the top of the Roxtec®
Multidiameter® blocks.

16. Remove the Roxtec® Multidiameter® blocks from

the cable mounting frame.

17. Pass the coaxes and power cable through the cable
mounting frame.
HINT: Again, It may be easier to connect, or tie-wrap,
the coaxes and power cable temporarily.
18. Re-install the cable mounting frame onto cable
passage channel using the four screws and flat
washers that were removed in step 7 above. .

19. Peel layers out of the upper and lower Roxtec®

Multidiameter® blocks to provide an opening in the
block that is just smaller than the outer diameter of
the cable that will pass through it. When
compressed the block should provide clamping force
on the cable and prevent it from moving in the block.

20. Two cables may be passed through each of the

Roxtec® Multidiameter® CM-20w40 blocks
provided.
21. If cables larger than 1.65cm/0.65in outer diameter
will be used, larger single-cable Roxtec®
Multidiameter CM-40 10-32 blocks are available to
allow three cables of up to3.25cm/1.28in diameter
to be used. The rubber bar and the three double-
cable Roxtec® Multidiameter blocks will be
replaced by the three larger Roxtec®
Multidiameter blocks.

3-5
5009-17 Installation Manual Installation

HINT: It may be helpful to put the clamp bar and

rubber bar in place (held loosely by one screw) to
hold some of the Roxtec® Multidiameter blocks in
place while you complete the others.

22. Re-install the clamp bar using the hardware removed

in step 14 above.

THIS CONNECTION

3.6.7.1. Jumper Selection

JP1 – JP4 are to couple in pull-up resistors for the below listed functions. JP5 selects the DC voltage
output on TS4.
JP1 SW1 – This output would be used for below decks band select - to control a band selection
switch or tone generator. Default is OPEN.
JP2 SW2 (blockage & RF radiation hazard output) - Used to control dual antenna arbitrator, in
dual antenna configurations, and provide TX Mute control to the Satellite Modem. Default is
SHORTED when blocked.
JP3 SW3 (reserved) - Reserved for future use.
JP4 AGC (external AGC input) - Pull-up for external AGC input from Satellite Modem which is
used to a positive satellite Network ID when the modem is on the correct network (therefore the
antenna is on the correct satellite). Default is SHORTED. NOTE: This jumper MUST be
removed when using iDirect 3000 & 5000 Series modems.
JP5 Voltage Output Select - Select 12VDC or 24VDC. Default is 12VDC.
3.6.7.2. J1 “Modem Console Port” connector
FCC compliance connection to an iDirect Satellite Modem can be made very easily by connecting a
Straight Serial RJ-45 cable from the J1 “Modem Console Port” connector on the Terminal Mounting
Strip to the Console port on the iDirect Modem. Your modem must be set
If your modem is Open AMIP compatible and you wish to use it in an Open AMIP configuration you
will use an Ethernet patch or cross-over cable as is appropriate to connect to your LAN.
Refer to the Setup – Modem Connections, Setup and Test chapter for more information.
3.6.7.3. TS1 Control Interface Connections.
AGC & GND - External AGC, or Modem Lock, input.
• External AGC input to the DAC-2202 must be 0 to 15 Volts DC analog signal, positive going
voltage proportional to satellite signal input level and must be real-time in its response to
antenna pointing.
• External Modem Lock from a satellite modem is used as a positive ID that the antenna is on
the desired satellite. This input is NOT used for Tracking purposes, it is only used for
satellite identification to acquire the correct satellite during search. To enable the external
modem input you must include a 2 in the SYSTEM TYPE parameter (If your system type is
presently 76 or 77, then change it to 78 or 79) and NID MUST be set to 0000.
• Connections - The modem lock signal connects to EXT AGC and a ground reference
from the modem. The expected signal from the modem allows 0VDC to +15VDC. Low
voltage indicates modem lock, high voltage indicates modem unlock.
• Testing - The input connections from the modem can be tested by selecting the external
AGC input and monitoring the displayed value. To select external AGC, set the tuning
frequency to 0000. Normally, AGC readings below 2048 are considered a low condition
and indicate modem lock and AGC readings above 2048 are considered a high condition
and indicate modem unlock.
[If you find the AGC reading for locked and unlocked conditions need to be reversed you
must add 128 to your current SYSTEM TYPE parameter].
Turn tracking OFF when checking the external AGC inputs. Be sure to properly retune the receiver
frequency when you are finished testing the external input.
• Operation - In NORMAL operation, AGC must be above Threshold AND external MODEM
Lock input must be locked to Track the satellite. If you are tracking a satellite signal and the
AGC is above threshold (Tracking light on solid) but the external AGC signal rises above 2.5

volts for more than 20 seconds (external MODEM input UNLOCKED) the ACU will
automatically retarget the selected satellite.
SW1 - Band Selection control output. This output is used to control below decks tone
generator(s), or coax switch(s), for band selection functions. The band selection control output is
driven by the band selected in the MODE – TRACKING display.
SW2 - The Blockage/TX Mute Control output is driven
by Blockage and RF Radiation Hazard functions. This
output will short to ground whenever the antenna is within
the programmed AZ LIMIT zone(s) or is Searching,
Targeting or is mispointed 0.5 degrees from satellite peak.
This output is commonly used to drive:
If your modem cannot use the Modem Console
Port connection you will have to provide a transmit
inhibit output from the ACU by connecting a SW2
wire connection to the modem to comply with FCC
Order 04-286 and WRC-03 Resolution 902.
• Dual or Quad Antenna Arbitrator coax switches in
dual antenna configurations. The coax switches
select which antenna is feeding signal to the
below decks equipment.
• Mute the Transmit output of the Satellite Modem
used in TX/RX antenna configurations when the
antenna is positioned where people may be
harmed by the transmit power emanating from
the antenna (RF Radiation Hazard).
• Mute the Transmit output of the Satellite Modem
used in TX/RX antenna configurations when the
antenna is mispointed by 0.5 degrees, or more,
and keep it muted until the antenna has been
within 0.2 degrees of peak pointing to the satellite
for a minimum of 5 seconds (FCC part 25.221 & 25.222 TX Mute requirement).
3.6.7.4. TS2 Synchro Gyro Compass Input.
Use the R1, R2, S1,S2 and S3 screw terminals to connect the Synchro Gyro Compass to the ACU.
3.6.7.5. TS3 Step-By-Step (SBS) Gyrocompass Input.
Use the COM, A, B and C screw terminals to connect the SBS Gyrocompass to the ACU. Some SBS
Gyro distribution boxes have terminals which are labeled S1, S2 & S3 instead of A, B and C.
3.6.7.6. TS4 Power
• VREG Screw terminal is used to provide a regulated DC operating voltage to ancillary
equipment. Voltage out is dependant upon which terminal mounting strip assembly is
provided. 126865-1 supplies 8Vdc @ 1Amp, while the 126865-2 assembly supplies 5Vdc
@ 2Amps.
• GND Screw terminal is the ground reference for the regulated and unregulated power
terminals.
• 12/24 Screw terminal is commonly used to provide operating voltage to a external GPS,
Dual Antenna Arbitrator or other below decks tone generators or switches. Voltage output
is based on the T.M.S assemblies JP5 jumper settings.

3.6.7.7. TS5 NMEA A/B, GPS output.

• RxA- and RxA+- screw terminals, which are
defined as the NMEA A connection is used to
connect to the ships Gyro Compass (Heading). The
NMEA0183 compliant inputs are then connected
via a 9 pin ribbon cable to the ACU’s J2 NMEA
communications port. A GPS (Latitude and
Longitude) input may also be connected, but is not
required because there is a GPS device already
installed in your antenna.. NOTE: If you connect a
ships GPS to the terminal mounting strip, you
MUST disconnect the GPS antenna on the
antenna pedestal.
• RxB- and RxB+ screw terminals, which are defined
as the NMEA B connection is used to connect to
the ships Gyro Compass (Heading). The
NMEA0183 compliant inputs are then connected
via a 9 pin ribbon cable to the ACU’s J2 NMEA
communications port. A GPS (Latitude and
Longitude) input may also be connected, but is not
required because there is a GPS device already
installed in your antenna.
• TxA- screw terminal is used to provide a Pseudo GPS (GGA and GLL formats) output to
other system components such as a Satellite Modem.

3.6.8. Other BDE connections

3.7. Final Checks

3.7.1. Visual/Electrical inspection

Do a visual inspection of your work to assure that everything is connected properly and all cables/wires are
secured.

3.7.2. Electrical - Double check wiring connections

Double check all your connections to assure that it is safe to energize the equipment.

3.8. Power-Up
Verify that all shipping straps and restrains have been removed prior to energizing the antenna.
When all equipment has been installed, turn ACU Power and Antenna power ON. The ACU will initially sequentially
display:
“SEA TEL – MASTER and DAC-2202 VER 6.xx” followed by,
“SEA TEL – RCVR and SCPC VER 5.xx” followed by,
“SEA TEL – IO MOD and COMMIF VER 1.xx” followed by,
“SEA TEL – REMOTE and INITIALIZING”. After initialization, the bottom line of the remote display will display
the antenna model number and the software version from the PCU.
Energize and check the other Below Decks Equipment to verify that all the equipment is operating. You will need to
assure that the ACU is setup correctly and that the antenna acquires the correct satellite before you will be able to
completely check all the below decks equipment for proper operation.

3.9. 61B Antenna Maintenance

3.9.1. Balancing the Antenna

The antenna and equipment frame are balanced at the factory however, after disassembly for shipping or
maintenance, balance adjustment may be necessary. The elevation and cross-level motors have a brake
mechanism built into them, therefore, power must be ON to release the brakes and DishScan and antenna
drive must be OFF to balance the antenna. . Do NOT remove any of the drive belts. Balancing is
accomplished by adding or removing balance trim weights at strategic locations to keep the antenna from
falling forward/backward or side to side. The antenna system is not pendulous so 'balanced' is defined as the
antenna remaining at rest when left in any position.
The “REMOTE BALANCE” parameter (located at the end of the Remote Parameters after REMOTE TILT) of the
ACU. When enabled, Remote Balance Mode temporarily turns DishScan, Azimuth, Elevation and Cross-Level
drive OFF. This function is required when trying to balance antenna systems that have a built-in brakes on
the elevation and cross-level motors.
Assure that Antenna power is ON and that the antenna has completed initialization.

At the ACU:
1. From the ACU - REMOTE BALANCE parameter: Enable balance mode (refer to your ACU manual).
The screen should now display “REMOTE BALANCE ON”.
At the Antenna:
2. At the Antenna: Balance the antenna with the elevation near horizon (referred to as front to back
balance) by adding, or subtracting, small counter-weights.
3. Then balance Cross Level axis (referred to as left-right balance) by moving existing counter-
weights from the left to the right or from the right to the left. Always move weight from
one location on the equipment frame to the same location on the opposite side of the equipment
frame (ie from the top left of the reflector mounting frame to the top right of the reflector
mounting frame). Do NOT add counter-weight during this step.
4. Last, balance the antenna with the elevation pointed at, or near, zenith (referred to as top to bottom
balance) by moving existing counter-weights from the top to the bottom or from the
bottom to the top. Always move weight from one location on the equipment frame to the same
location on the opposite side of the equipment frame (ie from the top left of the reflector
mounting frame to the bottom left of the reflector mounting frame). Do NOT add counter-weight
during this step.
5. When completed, the antenna will stay at any position it is pointed in for at least 5 minutes (with no
ship motion).
6. Do NOT cycle antenna power to re-Initialize the antenna. Return to the ACU, which is still in
REMOTE BALANCE mode, and press ENTER to exit Remote Balance Mode. When you exit Balance
Mode the antenna will be re-initialized, which turns DishScan, Azimuth, Elevation and Cross-Level
drive ON.

3.9.2. Fine Balance and Monitoring Motor Drive Torque

The DacRemP DISPTC graph chart provides a means for monitoring torque commands required for each
motor for diagnostic purposes and verifying antenna balance. By observing each trace, the required drive of
the antenna via the motor driver PCB may be established.

• To view the Torque Commands, select the graph chart.

• This chart displays the Torque Command errors for each axis via three traces, CL (Cross Level), LV
(Elevation), and AZ (Azimuth), at a fixed 0.195amps/vertical division.

3-12
Installation 5009-17 Installation Manual

• A normal trace display will be ± 1 divisions from the red reference line while under calm sea
conditions and with DishScan Drive turned off. See example below
• The Cross Level display will decrease (plots below red line) as the antenna requires drive to the left
and increase (plots above red line) as the antenna requires to the right.
Example: The antenna pictured in the screen capture below is imbalanced so that it is “Right Heavy”.
The CL trace is plotting above the red reference line (indicating that drive CCW is required to
maintain a 90°Cross-Level position).

• The Level display should decrease (plots below red line) as the antenna requires drive forward (Up in
elevation) and increase (plots above red line) as the antenna requires drive back (Down in elevation).
• Example: The antenna pictured in the screen capture below is imbalanced so that it is “Front Heavy”.
The LV trace is plotting above the red line (indicating that drive CW is required to maintain the
current elevation position).

3-13
5009-17 Installation Manual Installation

• The Azimuth display should decrease (plots below red line) as the antenna is driven CCW and
increase (plots above red line) as the antenna is rotated CW.

4.1. Operator Settings

Refer to the Operation chapter of this manual to set the Ship information. Latitude and Longitude should
automatically update when the GPS engine mounted on the antenna pedestal triangulates an accurate location, but
you may enter this information manually to begin. Except when integrating NMEA-0183 Gyro source, you will have to
enter the initial Heading of the ship, subsequently the ACU will then increment/decrement as the Gyro Compass
updates.
Next, set the Satellite information. Longitude of the desired satellite you wish to use and the receiver settings for it are
especially important.
At this point you should be able to target the desired satellite. Continue with the setup steps below to optimize the
parameters for your installation.

Setup – Ships Gyro Compass 5009-17 Installation Manual

5. Setup – Ships Gyro Compass

The Ships Gyro Compass connection provides true heading (heading of the ship relative to true North) input to the system. This
allows the ACU to target the antenna to a “true” Azimuth position to acquire any desired satellite.
After targeting this input keeps the antenna stabilized in Azimuth (keeps it pointed at the targeted satellite Azimuth). In normal
operation when viewing and ADMC recording in DacRemP, the “Relative Azimuth” trace should do exactly equal & opposite to
whatever the Heading trace does and the “Azimuth” trace should stay flat.
In normal operation the heading display in the ACU should at all times be the same value as the reading on the Gyro Compass
itself (this is also referred to as Gyro Following.).
If the ACU is not Following the Ships Gyro Compass correctly (un-erringly) refer to the Troubleshooting Gyro Compass
Problems.

5.1. GYRO TYPE

The GYRO TYPE parameter selects the type of gyro compass interface signal, the appropriate hardware connections
and the ratio of the expected input signal for ship turning compensation. Default GYRO TYPE parameter for all
systems is 0002 so that the ACU will properly follow for Step-By-Step or NMEA gyro signals.
If the Ships Gyro Compass output is Synchro, or there is NO Gyro Compass, the GYRO TYPE parameter must be set

90 for 90:1 Synchro with S/D Converter
36 for 36:1 Synchro with S/D Converter
2 for Step-By-Step gyro or NMEA gyro
1 for 1:1 Synchro with S/D Converter
0 for No Gyro linear AZ Search Mode (No Heading input available)

5.2. Updating the GYRO TYPE parameter

To manually update, press the LEFT arrow key to bring the cursor under the least significant character. Continue to
move the cursor until the desired character to be edited is underscored (selected). Use the UP or DOWN arrow keys to
increment or decrement the selected character.
Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify. When you are
finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup mode.
When you are finished making parameter changes, go to the SAVE NEW PARAMETERS display to save the changes you
have made.

5.3. If There is NO Ships Gyro Compass

Without heading input to the system the ACU will NOT be able to target, or stay stabilized ON, a “true” azimuth
pointing angle. This will make satellite acquisition much more difficult and the true azimuth value that any given
satellite should be at will not be displayed correctly.
This mode of operation is NOT recommended for ships. A better solution would be to provide a Satellite
Compass (multiple GPS Antenna device) to provide true heading input to the ACU. These devices are readily available
and are much less expensive than a Gyro Compass.
If there is NO Gyro Compass (ie on a large stationary rig which is anchored to the ocean floor) set the GYRO TYPE
parameter to 0000, the SWEEP INC parameter to 0047 and SAT REF (Satellite Reference Mode) MUST be turned ON.
This combination of settings will cause “No Gyro” Search pattern to be use to find the desired satellite (refer to the
setup – Searching lesson).

6.1. Determining the IF Tracking Frequency (MHz)

The IF Tracking frequency parameter is a value entered into the ACU’s MHZ Sub-Menu. The value itself may be
provided by your air-time provider and the MHz value will be entered directly in this sub-menu.
Or, the RF downlink frequency of a specific carrier on the desired satellite can be obtained from a satellite website and
calculated by using the formula RF- LO = IF. When you take the Satellite Transponder Downlink RF value and subtract
the LNB’s Local Oscillator (LO) Value, the resultant value will equal the Intermediate Frequency (IF). It is this IF value
that will be entered into the ACU for tracking purposes.
Example assuming an LNB LO value of 11.25GHz: 12268.0 MHz – 11250.0 MHz = 1018.0 MHz IF

6.2. KHz
The KHz rate entered into the ACU is an absolute value which also may have been provided by your air-time provider,
or have been calculated, and is entered directly in this sub-menu window.
In the example above, 1018.0 MHz was calculated (1018 MHz 000 KHz) therefore, the KHz entry would be 000. If the
provided/calculated value had been 1018.250, 1018 would have been entered in the MHz window and 250 would be
entered in the KHz window.

6.3. FEC

6.3.1. L-Band SCPC Receiver

The Forward Error Correction rate entered into the ACU should always be set to SCPC with an L-Band SCPC
receiver card installed in the ACU.

6.4. Tone

6.4.1. VSAT Application

In the Series 09 VSAT antenna system, there is no need for below decks band selection and thus there is no
applicable use for tone control. For VSAT antenna systems that have voltage and tone controlled multiband
LNB’s installed, you will use the tracking band selection to control/toggle the tone state of a 22 KHz tone
generator (installed in the above decks equipment). For detailed information, refer to the “SETUP-Band
Select” section of this document.

6.5. Volt

6.5.1. VSAT Application

Above Decks Powered - The LNB’s installed onto all Series 09 VSAT antenna systems are powered by the
antenna itself (above decks), and thus there is no applicable use for VOLT control. For antenna systems that
have voltage and tone controlled multiband LNB’s installed, you will use the tracking band selection to
control/toggle the voltage output of the ADE 400MHz FSK modem. For detailed information, refer to the
“SETUP-Band Select” section of this document.

6.6. SAT SKEW

SKEW is used to optimize the polarization of the feed to the desired satellite signal. In VSAT systems this is normally
adjusted during the cross-pol isolation testing with the Network or Satellite Provider (refer to (Optimizing Cross-Pol
Isolation).

6.7. NID
In VSAT systems the Network Identification parameter should always be set to 0000 to allow external network lock to
be supplied into the ACU from the satellite modem.

Setup – Band Selection 5009-17 Installation Manual

7. Setup – Band Selection

To properly control the band selection of the LNB(s) mounted on the antenna the TRACK DISP (Tracking Display) parameter
must be set correctly. Which value the TRACK DISP parameter is set to depends on the hardware configuration of the antenna
pedestal.
The xx09-17 and xx09-33 antenna pedestals come with the waveguide diplexer and LNB to provide the additional Co-Pol RXIF
output to the Cross-Pol/Co-Pol select coax switch (all of the systems come with the switch and coax installed, so you can easily
upgrade the antenna with the Co-Pol hardware).
The TRACK DISP parameter controls Tone, Voltage and Aux functions remotely on the antenna pedestal. Voltage and Tone are
used to select the desired band of dual-band, tri-band and quad-band LNBs. The Aux function controls the Cross-Pol/Co-Pol
select switch.
Sea Tel provides quad-band LNBs as a default LNBs on the 09 Series antennas, therefore, the default TRACK DISP parameter for
Cross-Pol only systems is 0170 and 0130 for 09 antennas with Cross-Pol AND Co-Pol LNBs.

Setup – Targeting 5009-17 Installation Manual

8. Setup – Targeting
In this lesson you will learn how to optimize the targeting of the antenna to land on or near a desired satellite (within +/-1
degree).

8.1. AUTO TRIM

The Auto Trim function will automatically calculate and set the required Azimuth and Elevation trim offset parameters
required to properly calibrate the antennas display to the mechanical angle of the antenna itself, while peaked ON
satellite.
Refer to “Optimizing Targeting” in the Setup section of this manual for further details on the parameters settings.
To enable this function, the Antenna MUST be actively tracking the satellite with positive SAT ID and elevation of the
antenna must be less than 83 degrees and the ACU must NOT be set for Inclined Orbit Search. After locating the
satellite, with Tracking ON, wait at least 30 seconds before performing the AUTO TRIM feature, this will allow sufficient
time for the antenna to peak up on signal. It is equally important that you verify that the system is tracking the
CORRECT satellite (verify video is produced on the Televisions in a TVRO system or verify a RX lock indication on the
satellite modem in a VSAT system).
While in the AUTO TRIM sub-menu, press the LEFT arrow key to bring start the calibration procedure, the display
should read AUTO TRIM SETUP, press the ENTER key to submit. AUTO TRIM SAVED will be displayed, indicating the
proper AZ and EL trims were submitted to RAM. This does not save these parameters to NVRAM, in order to save to
memory, continue down through the setup mode parameters until the SETUP SAVE NEW PARAMETERS sub menu
is displayed. Press the RIGHT arrow and then press the ENTER key. The display should now report that the
parameters were saved. From the AUTO TRIM SETUP screen, press the NEXT key (DAC2202) without hitting ENTER
to escape this screen without submitting the new AZ and EL Trim values.
NOTE: AUTO TRIM LOCKED will be displayed on the front panel, indicating that the AUTO TRIM Feature is NOT
allowed if all of these conditions are not met:
The ACU must be actively tracking a satellite (AGC above threshold) and
The ACU must have positive SAT ID (internal NID match or external RX lock received from the Satellite
Modem) and
The elevation angle of the antenna must be LESS than 75 degrees and
The ACU must NOT be set for Inclined Orbit Search.

8.2. Manually Optimizing Targeting

First, assure that all of your Ship & Satellite settings in the ACU are correct.
1. Target the desired satellite, immediately turn Tracking OFF, and record the Azimuth and Elevation positions in
the “ANTENNA“ display of the ACU (these are the Calculated positions).
2. Turn Tracking ON, allow the antenna to “Search” for the targeted satellite and assure that it has acquired (and
peaks up on) the satellite that you targeted.
3. Allow several minutes for the antenna to “peak” on the signal, and then record the Azimuth and Elevation
positions while peaked on satellite (these are the Peak positions). Again, assure that it has acquired the
satellite that you targeted!
4. Subtract the Peak Positions from the Calculated Positions to determine the amount of Trim which is required.
Refer to the ACU Setup information to key in the required value of Elevation Trim.
5. Continue with Azimuth trim, then re-target the satellite several times to verify that targeting is now driving
the antenna to a position that is within +/- 1.0 degrees of where the satellite signal is located.
EXAMPLE: The ACU targets to an Elevation position of 30.0 degrees and an Azimuth position of 180.2 (Calculated),
you find that Peak Elevation while ON your desired satellite is 31.5 degrees and Peak Azimuth is 178.0. You would
enter an EL TRIM value of –1.5 degrees (displayed as -0015) and an AZ TRIM of +2.2 degrees (displayed as 0022).
After these trims values had been set, your peak on satellite Azimuth and Elevation displays would be very near 180.2
and 30.0 respectively.

8.3. EL TRIM
Elevation trim offset parameter is entered in tenths of degrees. Adjusts display to correct for antenna alignment errors
or imbalances in the antenna system. Increase number to increase display. Refer to “Optimizing Targeting” in the
Setup section of your antenna manual.
To update: While in the EL TRIM sub-menu, press the LEFT arrow key to bring the cursor under the ones digit. Press
the UP or DOWN arrow key to increment or decrement the selected digit. Minus values are entered by decrementing
below zero. Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify.
When you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup mode.
Continue with Azimuth trim, then re-target the satellite several times to verify that targeting is now driving the
antenna to a position that is within +/- 1.0 degrees of where the satellite signal is located.

8.4. AZ TRIM
Azimuth trim offset parameter is entered in tenths of degrees. Offsets true azimuth angle display to compensate for
installation alignment errors when used with Ships Gyro Compass input reference. Azimuth Trim does not affect
REL azimuth reading. Increase number to increase displayed value. Refer to “Optimizing Targeting” in the Setup
section of your antenna manual.
To update: While in the AZ TRIM sub-menu, press the LEFT arrow key to bring the cursor under the ones digit. Press
the UP or DOWN arrow key to increment or decrement the selected digit. Minus values are entered by decrementing
below zero. Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify.
When you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup mode.
Then re-target the satellite several times to verify that targeting is now driving the antenna to a position that is within
+/- 1.0 degrees of where the satellite signal is located.

Setup – Home Flag Offset 5009-17 Installation Manual

9. Setup – Home Flag Offset

Home Flag Offset is used to calibrate the relative azimuth value of the antenna to the bow line of the ship. This assures that the
encoder input increments/decrements from this initialization value so that the encoder does not have to be precision aligned.
When the antenna is pointed in-line with the bow (parallel to the bow) the “Relative” display value should be 000.0 Relative
(360.0 = 000.0). Good calibration is especially important if blockage mapping is used, because the values entered into the AZ
LIMIT parameters are entered in Relative Azimuth. The default Home Flag Offset value saved in the PCU is 000.
The Home Flag Sensor mounted on the pedestal is actuated by
a metal tab mounted on the azimuth spindle which causes it to
produce the “Home Flag” signal.
The default mounting of the radome is with its bow reference
in-line with the bow and the base hatch in-line with the stern
(aft reference of the radome). There are valid reasons for
mounting the ADE in a different orientation than the default.
One of these would be that the hatch of radome needs to be
oriented inboard of the ship for safe entry into the dome (ie
ADE is mounted on the Port, or Starboard, edge of the ship and
safe entry is only available from inboard deck or inboard mast
rungs).
Observe initialization of the antenna. When Azimuth
drives CW and then stops at “Home” position, VISUALLY
compare the antennas pointing, while at Home position, to the
bow-line of the ship (parallel to the Bow).
If it appears to be very close to being parallel to the bow,
you will not need to change the HFO and should proceed with
Optimizing Targeting. When “Optimizing Targeting” small Figure 9-1 Antenna stops In-line with Bow
variations (up to +/- 5.0 degrees) in Azimuth can be easily
corrected using the AZ TRIM parameter.
If it is NOT close (stops before the bow or continues to drive past the bow) HFO needs to be adjusted.
If the antenna is pointing to the LEFT of the bow line: If the antenna stops driving before the bow line, when
targeting a satellite it will fall short of the desired satellite by exactly the same number of degrees that it fell short of
the bow line. You must calibrate HFO using either of the methods below.
If the antenna is pointing to the RIGHT of the bow line: If the antenna continues to drive past the bow line,
when targeting a satellite it will overshoot the desired satellite by exactly the same number of degrees that it went
past the bow line. You must calibrate HFO using either of the methods below.
If you find that a large value of AZ TRIM parameter has been used to calibrate the antenna, This indicates that the
Relative position is incorrect and should be “calibrated” using the correct HFO value instead of an Azimuth Trim offset.
If the radome was purposely rotated, has a large value of AZ TRIM or was inaccurately installed (greater than +/- 5 degrees),
there are twos way of setting Home Flag to compensate for the mounting error. They are:

9.1. Electronic Calibration of Relative Antenna Position (Home Flag Offset)

Above, you VISUALLY compared the antenna pointing, while at “Home” position, to the bow-line of the ship and found
that the antenna pointing was NOT close to being parallel to the bow-line. It stopped before the bow or went past
the bow OR you found AZ TRIM has been set to a large value, therefore, HFO needs to be adjusted.
Ascertain the exact amount of error using the appropriate procedure below, enter the HFO to calibrate the antenna to
the ship, save the value and re-initialize the antenna to begin using the new value.

9.1.1. You Found a Large AZ TRIM value:

If Targeting has been optimized by entering a large value of AZ TRIM; First, verify that you are able to
repeatably accurately target a desired satellite (within +/- 1.0 degrees). Then you can use the AZ TRIM value
to calculate the value of HFO you should use (so you can set AZ TRIM to zero). AZ Trim is entered as the
number of tenths of degrees. You will have to convert the AZ TRIM value to the nearest whole degree
(round up or down as needed). Calculated HFO value is also rounded to the nearest whole number.

9-1
5009-17 Installation Manual Setup – Home Flag Offset

If AZ TRIM was a plus value: HFO = (TRIM / 360) x 255 Example: AZ TRIM was 0200 (plus 20 degrees).
HFO = (20/360) x 255 = (0.0556) x 255 = 14.16 round off to 14. Set, and Save, HFO to 014 using the “To
Enter the HFO value” procedure below.
If AZ TRIM was a negative value: HFO = ((360-TRIM) / 360)) x 255 Example: AZ TRIM = -0450 (minus 45
degrees). HFO = ((360 – 45) / 360)) x 255 = (315 / 360) x 255 = 0.875 x 255 = 223.125 round of to 223. Set,
and Save, HFO to 223 using the “To Enter the HFO value” procedure below.

9.1.2. You Observe “Home” Pointing is LEFT of the Bow-line:

1. In this example, I observe that the
Home position is short of the bow
line.
2. I estimate that it is about 45 degrees.
3. I target my desired satellite and
record the Calculated Azimuth to be
180.5.
4. I drive UP (I estimated that I will need
to go UP about 45 degrees) and
finally find my desired satellite.
5. Turn tracking ON to let the ACU peak
the signal up. When peaked, the
Azimuth is 227.0 degrees.
6. I subtract Calculated from Peak (227
– 0180.5 = 46.5) and difference is
46.5 degrees.
7. I can calculate what the correct value
for the Home position of the antenna Figure 9-2 Antenna stopped before the Bow
by subtracting (because “home” was
to the left of bow) this difference of 46.5 from the bow line position 360.0. Therefore “home”
should be 313.5 Relative.
8. I now calculate the HFO = (313.5 / 360) x 255 = 0.87 x 255 = 222.06 which I round off to 222.
9. I set, and Save, HFO to 222 using the “To Enter the HFO value” procedure below. After I re-initialize
the relative position of the antenna is now calibrated.
10. If there is a small amount of error remaining, use AZ TRIM in the Optimizing Targeting procedure to
correct it.

9.1.3. You Observe “Home” Pointing is RIGHT of the Bow-line:

1. In this example, I observe that the
Home position is past the bow line.
2. I estimate that it is about 90
degrees.
3. I target my desired satellite and
record the Calculated Azimuth to
be 180.0.
4. I drive DOWN (I estimated that I
will need to go DOWN about 89
degrees) and finally find my
desired satellite.
5. Turn tracking ON to let the ACU
peak the signal up. When peaked,
the Azimuth is 90.0 degrees.
6. I subtract Calculated from Peak
(180.0 – 90.0 = 90.0) and
difference is 90.0 degrees.
7. I can calculate what the correct Figure 9-3 Antenna stops past the Bow
value for the Home position of the
antenna by adding (because

9-2
Setup – Home Flag Offset 5009-17 Installation Manual

“home” was to the right of bow) this difference of 09.0 to the bow line position 000.0. Therefore
“home” should be 90.0 Relative.
8. I now calculate the HFO = = ((90.0) / 360)) x 255 = 0.25 x 255 = 63.75 which I round off to 64.
9. I set, and Save, HFO to 222 using the “To Enter the HFO value” procedure below. After I re-initialize
the relative position of the antenna is now calibrated.
10. If there is a small amount of error remaining, I will use AZ TRIM in the Optimizing Targeting
procedure to correct it.

9.1.4. To Enter the HFO value in the DAC_2202:

To enter the calculated HFO value, press & hold both LEFT and RIGHT arrows for six seconds to enter the
parameter menu at the EL TRIM parameter window. Press DOWN arrow key numerous times (about 21) until
you have selected the REMOTE COMMAND window.
In the REMOTE COMMAND window, press the LEFT arrow key until you have underscored the left most
character in the displayed value (ie the A in "A0000"). Use the UP/DOWN arrow keys to increment/decrement
the underscored character until it is upper case N (“N0000” should appear in the command window). Press
the RIGHT arrow key to move the cursor under the most significant digit, then use the UP arrow key to
increment it to a value of 6 (the display is now “N6000”). Set the three digits to the right of the 6 to the three
digit HFO value from 000 to 255 (corresponding to 0 to 360 degrees) that you calculated above. Use the
LEFT/RIGHT keys to underscore the desired digit(s) then use the UP/DOWN arrow keys to
increment/decrement the underscored value. When you have finished editing the display value, press ENTER
to send the HFO value command to the PCU (but it is not save yet).
If you want to find out what the current HFO value is key in N6999 and hit ENTER.
When completed, you must save the desired HFO value. Press ENTER several times to select the REMOTE
PARAMETERS display. Press the LEFT or RIGHT arrow key to enter writing mode and then press the ENTER to
save the HFO value in the PCUs NVRAM.
EXAMPLE: In the “You Observe “Home” Pointing is LEFT of the Bow-line” example above, the HFO
calculated was 222. To enter this value:
1. Set the Remote Command value to "N6222".
2. Press ENTER to send this HFO to the PCU. The display should now show "N0222".
3. When completed, you must save the desired HFO value. Press ENTER several times to select the
REMOTE PARAMETERS display. Press the LEFT or RIGHT arrow key to enter writing mode and
then press the ENTER to save the HFO value in the PCUs NVRAM.
You must drive the antenna CW in azimuth until the home switch is actuated, or re-initialize the antenna to
begin using the new HFO value you have entered and saved. To re-initialize the antenna from the
REMOTE COMMAND window of the ACU;
4. Press UP arrow key several times to return to the REMOTE COMMAND display.
5. Press the LEFT or RIGHT arrow key to enter edit mode. Use the LEFT/RIGHT and UP/DOWN
arrow keys to set the character and digits to "^0090" and then press the ENTER key.
This resets the PCU on the antenna. The antenna will reinitialize with this command (Performs a similar
function as a power reset of the antenna) and the new home flag offset value will be used to calibrate the
Relative position of the antenna.

9-3
5009-17 Installation Manual Setup – Home Flag Offset

9.2. Mechanical Calibration of Relative Antenna Position (Home Flag Offset)

During initialization, azimuth drives the antenna CW until the Home Flag Switch senses the trailing edge of the metal
tab (as shown in the left picture above). The sensor will appear to go past the metal tab, then come back to the
trailing edge of the metal tab and stay there. This “home” position orients the pedestal to the “BOW” reference in the
radome which is directly forward of the entry hatch in the radome base. The Home Flag signal into the PCU “presets”
the relative position counter to the value stored in the Home Flag Offset (default value saved in the PCUs is 000).
This assures that the encoder input increments and decrements from this initialization value, therefore, does not have
to be precision aligned.
The metal Home Flag tab is mounted in a nylon clamp assembly. The nylon bolt/nut can be loosened to rotate the
clamp around underneath the power ring. (as shown in the center picture above).
In the simplest scenario, if you could rotate the antenna pedestal to be in-line with the bow and then rotate the home
flag clamp assembly around until the trailing edge is centered on the body of the home flag sensor, and tighten the
clamp HFO would be set close enough for “Optimizing Targeting” procedure to be effective. Unfortunately, rarely is
the equipment going to align where the clamp and sensor will be easy to access, reach and see, to align it this way.
The hex bolt heads in the plate below the Home Flag Clamp assembly are 60 degrees apart (as shown in the picture
on the right above) and allow multiple points of view to calibrate rotation of the clamp to.
If you installed the ADE with the “Bow” reference of the radome oriented in-line with the bow, the antenna pedestal
will be pointed in-line with the ships bow when stopped at the Home Flag position on completion of initialization
(before it targets a satellite) as shown in Figure 1 in the Electrical Calibration Procedure above. In this case, when the
antenna stops at the home flag and is pointed in-line with the Bow, Home Flag Offset (HFO) should be set to zero and
mechanical position of the metal Home Flag tab should be left at the 0° (default) position. Any small mechanical
mount error will be compensated when “Optimizing Targeting” is accomplished to correct for small variations of up to
+/- 5.0 degrees.
If the ADE is installed with the “Bow” reference of the radome oriented 45° to starboard the pedestal, when at home
flag position, will be pointed 45° CCW of the bow (at relative 315° as shown in Figure 2 in the Electrical Calibration
Procedure above). To compensate for this, loosen the home flag clamp, rotate the trailing edge of the metal home flag
tab CW 45° and tighten the clamp bolt (use caution not to tighten too much and strip the nylon hardware)..
You will have to estimate this 45° rotation based on the 60° spacing of the hex bolt centers. Re-initialize the antenna
and verify that when at home flag position it is pointed in-line with the ships bow. Do NOT change the Home Flag
Offset value saved in the PCU, small variations will be compensated for when “Optimizing Targeting” is
accomplished.
If the ADE is installed with the “Bow” reference of the radome oriented 90° to port, the pedestal when at home flag
position, will be pointed 90° CW of the bow (at relative 090° as shown in Figure 3 in the Electrical Calibration
Procedure above). To compensate for this, loosen the home flag clamp, rotate the trailing edge of the metal home flag
tab CCW 90° and tighten the clamp bolt (use caution not to tighten too much and strip the nylon hardware)..
You will have to estimate this 90° rotation based on the 60° spacing of the hex bolt centers. Re-initialize the antenna
and verify that when at home flag position it is pointed in-line with the ships bow. Do NOT change the Home Flag
Offset value saved in the PCU, small variations will be compensated for when “Optimizing Targeting” is
accomplished.

10. Setup – Searching

10.1. Searching Operation

The ACU will initiate an automated search pattern after AGC falls below the current Threshold setting (indicates that
satellite signal has been lost). The SEARCH DELAY parameter sets the amount of delay, in seconds, that the ACU will
wait after AGC has fallen below the threshold value before it starts a search.
Search can be initiated manually by pressing the NEXT key as many times as required to access the SETUP menu, then
press the ENTER Key to access the SEARCH sub-menu and then press the UP arrow key (starts a search from the
current antenna position). While in the SEARCH sub-menu, pressing the DOWN arrow key will stop the current search.
Search is terminated automatically when the AGC level exceeds the threshold value and Tracking begins.
The ACU can be configured to use one of three search patterns. Each of the search patterns are described below.
Each description includes information about the settings involved in configuring the ACU to select that particular
pattern and the values that those settings would be set to, to optimize the pattern for your antenna model and the
frequency band being used.
The dimensions and timing of the search pattern are determined by the SETUP parameters SEARCH INC, SEARCH
LIMIT, SEARCH DELAY and SWEEP INC. Search is also affected by the Threshold and the internal receiver
settings under the Satellite menu. To change any one of these parameters, refer to “Changing the Search Parameters”
procedures below.
All three search patterns are conducted in a two-axis pattern consisting of alternate movements in azimuth and
elevation or along the polarization angle. The size and direction of the movements are increased and reversed every
other time resulting in an increasing spiral pattern as shown.

10.1.1. Default Standard (Box) Search Pattern

The factory default search pattern in the ACU is a standard “box” pattern. You configure the ACU to use this
pattern by using the following settings:
SEARCH INC - set to the default value for the frequency band that your antenna model is currently
being used for (typically 15 counts).
SEARCH LIMIT – initially set to the default value. After targeting has been optimized, the search
limit can be adjusted if desired.
SEARCH DELAY – default, or any number of seconds from 1-255 that you would prefer that the
ACU wait before starting an automatic search.
SWEEP INC – default value (this parameter is not used in this search pattern).
GYRO TYPE – must NOT be set to zero.
SAT REF mode – may be ON if you are experiencing frequent, or constant, gyro read errors (error
code 0001). Must be ON if you are using NMEA Gyro input.
Target any satellite longitude value which includes even tenths digit values (ie SAT 101.0 W or SAT 101.2 W).
If the desired satellite longitude includes an odd tenths digit, you must round it up, or down, one tenth to
make the tenths digit EVEN. The Antenna Control Unit calculates the Azimuth, Elevation and Polarization
values it will target the antenna. Initially the antenna will go to a position that is 8 degrees above the
calculated elevation, until Azimuth and Polarization have had time to complete adjustment. Then the
antenna will drive down to the calculated elevation, which is the “Start” of the search pattern in the graphic
below.
The antenna will then search up in azimuth one Search Increment, search up one Search Increment in
elevation, search down two Search Increments in azimuth, search down two Search Increments in elevation,
etc until Search Limit is reached. When the end of the search pattern is reached, the ACU will retarget the
antenna to the start point shown in the graphic below.
If the desired signal is found (AND network lock is achieved in the satellite modem) at this position, or
anywhere within the search pattern, the ACU will terminate search and go into Tracking mode. If the desired
signal is not found the ACU will wait SEARCH DELAY seconds and then begin the search pattern again. This
cycle will repeat until the desired satellite signal is found or the operator intervenes.

5009-17 Installation Manual Setup – Searching

10.1.2. Inclined Orbit Search Pattern

Some older satellites, in order to save fuel to keep them exactly positioned over the Equator, are in an
inclined geosynchronous orbit. The satellite remains geosynchronous but is no longer geostationary. From a
fixed observation point on Earth, it would appear to trace out a figure-eight with lobes oriented north-
southward once every twenty-four hours. The north-south excursions of the satellite may be too far off the
center point for a default box search pattern to find that satellite at all times during the 24 hour period.
You can configure the ACU to do a special search pattern for a satellite that is in an inclined orbit by using the
following settings:
SEARCH INC - set to the default value for the frequency band that your antenna model is currently
being used for (typically 15 counts).
SEARCH LIMIT – leave this set to the default value for your antenna model.
SEARCH DELAY – default, or any number of seconds from 1-255 that you would prefer that the
ACU wait before starting an automatic search.
SWEEP INC – set to 192 if your antenna is a Series 04 or Series 06 or Series 09. Set to 193 if your
antenna is a Series 97, Series 00 or Series 07. This parameter sets the sweep increment (shown in
the graphic above) to be +/- 8.0 degrees above/below the satellite arc.
GYRO TYPE – must NOT be set to zero.
SAT REF mode – may be ON if you are experiencing frequent, or constant, gyro read errors (error
code 0001). Must be ON if you are using NMEA Gyro input.
Target the desired satellite longitude value but include an odd tenths digit (ie if you desire to target inclined
satellite 186.0 W you would key in SAT 186.1 W for the ACU to do an inclined search). The Antenna Control
Unit calculates the Azimuth, Elevation and Polarization values it will target the antenna to.
Initially the antenna will go to a calculated position that is half of SWEEP INCR degrees above, and
perpendicular to, the satellite arc (along the same angle as polarization for the desired satellite). This position
is the “Start” of the search pattern in the graphic above. Then the antenna will drive down along the
polarization angle SWEEP INCR degrees, step one Search Increment to the right (parallel to the satellite arc),
search up along the polarization angle SWEEP INCR degrees, step two Search Increments to the left, search
down, etc expanding out in the search pattern until Search Limit is reached. When the end of the search
pattern is reached, the ACU will retarget the antenna to the calculated Azimuth and Elevation point.
If the desired signal is found (AND network lock is achieved in the satellite modem) at this position, or
anywhere within the search pattern, the ACU will terminate search and go into Tracking mode. If the desired
signal is not found the ACU will wait SEARCH DELAY, then target the antenna to start point shown in the
graphic above and begin the search pattern again. This cycle will repeat until the desired satellite signal is
found or the operator intervenes.

10.1.3. No Gyro Search Pattern

If the ship does not have a gyro compass to use as a heading input to the Antenna Control Unit, you may
manually key in the actual heading of the vessel and then re-target the desired satellite, every time you need
to re-target a satellite, or configure the ACU to do a “No Gyro Search Pattern”.
10-2
Setup – Searching 5009-17 Installation Manual

You configure the ACU to use this pattern by using the following settings:
SEARCH INC - set to the default value for the frequency band that your antenna model is currently
being used for (typically 15 counts).
SEARCH LIMIT – leave this set to the default value.
SEARCH DELAY – default, or any number of seconds from 1-255 that you would prefer that the
ACU wait before starting an automatic search.
SWEEP INC – Larger antennas should have slower speeds and smaller antennas should have faster
speeds:
Larger antennas should have slower speeds set to 0047 (= 5 degrees/second) for 2.4M to
3.6M antenna systems).
Mid size antennas can be driven a little faster, set to 0063 (= 8 degrees/second) for 2M
antennas models).
Smaller antennas should have faster speeds, set to 0079 (= 18 degrees/second) for all
0.8M to 1.5M antenna models).
GYRO TYPE – MUST be set to zero for this search pattern.
SAT REF mode – MUST be ON for this search pattern.
Target any satellite longitude value which includes even tenths digit values (ie SAT 101.0 W or SAT 101.2 W).
If the desired satellite longitude includes an odd tenths digit, you must round it up, or down, one tenth to
make the tenths digit EVEN. The Antenna Control Unit calculates the Azimuth, Elevation and Polarization
values it will use to target the antenna. However, without heading input, the ACU cannot target a “true
azimuth” position (relative to true North). It will target the antenna to the calculated elevation and a
repeatable “Start” relative azimuth position. In Series 04 antennas this relative position will be 90 degrees
away from the nearest mechanical stop. In all other antennas it will be 000 degrees relative.
Initially the antenna will go to the “Start” relative azimuth position at the calculated elevation. Then the
antenna will search up 450 degrees in azimuth, search up one Search Increment in elevation, search down
450 degrees in azimuth, search down two Search Increments in elevation, etc until Search Limit is reached.
When the end of the search pattern is reached, the ACU will retarget the antenna back to the start point
shown in the graphic below.
If the desired signal is found (AND network lock is achieved in the satellite modem) at this position, or
anywhere within the search pattern, the ACU will terminate search and go into Tracking mode. If the desired
signal is not found the ACU will wait SEARCH DELAY seconds and then begin the search pattern again. This
cycle will repeat until the desired satellite signal is found or the operator intervenes.

10.2. Changing the Search Parameters

The information above described what some of these parameters need to be set to for a specific search pattern.
Below are some additional pieces of information on the other parameters and the steps to change any one of these
parameters.

10-3
5009-17 Installation Manual Setup – Searching

10.2.1. AUTO THRES

Sets offset of AGC tracking threshold above the average noise floor. Units are in A/D counts, approximately
20 counts/dB. A setting of 0 disables auto threshold, therefore, the operator would have to manually enter a
threshold value.
When AUTO THRESHOLD is enabled (any value between 1-255), the ACU automatically re-sets the AGC
tracking threshold whenever the antenna Targets (AZ, EL or SAT) or Searches. The new AGC threshold is set
to the average signal level input (approximate background noise level) plus the AUTO THRES offset value.
EXAMPLE: If the Noise Floor off satellite is 1000 counts of AGC and Auto Threshold is set to 100, Threshold
will be set to approximately 1100 after the antenna has finished targeting or Searching.
To change the Automatic Threshold value OR manually set threshold; Note the Peak “on satellite” AGC value,
move EL and note the “off satellite” (Noise Floor) AGC value. Calculate the Difference between Peak AGC and
Noise Floor AGC. AUTO THRES should be set to 1/3 (to ½) of the Difference. This will usually be around 100
counts (3 dB) for a typical antenna configuration. Changes to this parameter may be required based on
carrier tracking frequency, possible adjacent satellite, or ambient interference with desired satellite.

10.2.5. SEARCH INC

Sets size of search pattern increment. Units are in pedestal step resolution (12 steps per degree). The
suggested setting is equal to the full 3dB beamwidth of your antenna. Default value is 15 these systems.
To manually update, press the LEFT arrow key to bring the cursor under the least significant character.
Continue to move the cursor until the desired character to be edited is underscored (selected). Use the UP or

you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup
mode.

10.2.6. SEARCH LIMIT

Sets the overall peak to peak size of the search pattern. Units are in pedestal step resolution (12 steps per
degree). Default value is 100 for these systems.
After you have optimized your Targeting (refer to Optimizing Targeting) you may wish to reduce the size of
the Search pattern to avoid Tracking on an adjacent satellite (ie set to 50% of its default value so that in the
future it will only search half as far from your targeted position).

mode.

10.2.7. SEARCH DELAY

Sets the time-out for automatic initiation of a search operation when the signal level (AGC) drops below
threshold. Units are in seconds. Range is 0-255 seconds. Default setting is 30 seconds. A setting of 0
disables the automatic search initiation.
To manually update, press the LEFT arrow key to bring the cursor under the least significant character.
Continue to move the cursor until the desired character to be edited is underscored (selected). Use the UP or
DOWN arrow keys to increment or decrement the selected character.

increment dimension of an Inclined Orbit search (refer to the search pattern information above).
To manually update, press the LEFT arrow key to bring the cursor under the least significant character.
Continue to move the cursor until the desired character to be edited is underscored (selected). Use the UP or
DOWN arrow keys to increment or decrement the selected character.
Use the LEFT or RIGHT arrow key to move the cursor left or right to select other characters to modify. When
you are finished modifying press ENTER to execute the new value OR press NEXT to abort and exit setup
mode.

10.3. SAVE NEW PARAMETERS

Parameters that have been changed are only temporarily changed until they are SAVED. If changes are made and not
stored, they will still be effective but will be lost when power is removed or the RESET key is pressed. Simultaneously
press, and quickly release the LEFT & RIGHT arrow keys to access “SAVE NEW PARAMETERS” directly from any other

Setup – Blockage & RF Radiation Hazard Zones 5009-17 Installation Manual

11. Setup – Blockage & RF Radiation Hazard Zones

This section discusses how to set up blockage, or RF Radiation Hazard, zones in the ACU.

11.1. Radiation Hazard and Blockage Mapping (AZ LIMIT parameters)

The ACU can be programmed with relative azimuth sectors (zones) where blockage exists or where transmit power
would endanger personnel who are frequently in that area. Your ACU software may allow you to set four zones or it
will only three zones and include +5 volt polarization.
When the AZ LIMIT parameters are set to create these ZONES (up to four), several things happen when the antenna is
within one of the zones:
1. Tracking continues as long as the AGC value is greater than the Threshold value. When the AGC value drops
below Threshold, the antenna will wait “Search Delay” parameter amount of time and then re-target the
satellite you targeted last (if 4 value is included in SYSTEM TYPE). Timeout and re-target will continue until
the satellite is re-acquired and tracking can resume.
2. “BLOCKED” will be displayed in the TRACKING window wherever the antenna is inside one of the zones.
3. A contact closure to ground (or an open if the blockage logic is reversed – See SYSTEM TYPE 16 value) is
provided on the SW2 terminal of the Terminal Mounting Strip. This Switch output provides a “Blocked”, “RF
Radiation Hazard” or “FCC TX Mute” logic output. When the antenna exits the zone it will be on satellite,
tracking and the SW2 logic contact closure will open.
The lower and upper limits are user programmable and are stored in NVRAM within the ACU parameter list.
AZ LIMIT 1 is the Lower Relative AZ limit (this is the more counter-clockwise of the two points, even if it is
numerically larger). AZ LIMIT 2 is the Upper Relative AZ limit (the more clockwise of the two points) for
pattern mapping of ZONE 1. Enter the elevation value that represents the top of the blockage between the
two azimuth limit points in the EL LIMIT 12 parameter.
AZ LIMIT 3 is the Lower Relative AZ limit (CCW point) and AZ LIMIT 4 is the Upper Relative AZ limit (CW
point) for pattern mapping of ZONE 2. Enter the elevation value that represents the top of the blockage
between the two azimuth limit points in the EL LIMIT 34 parameter.
AZ LIMIT 5 is the Lower Relative AZ limit (CCW point) and AZ LIMIT 6 is the Upper Relative AZ limit (CW
point) for pattern mapping of ZONE 3. Enter the elevation value that represents the top of the blockage
between the two azimuth limit points in the EL LIMIT 56 parameter.
AZ LIMIT 7 is the Lower Relative AZ limit (CCW point) and AZ LIMIT 8 is the Upper Relative AZ limit (CW
point) for pattern mapping of ZONE 4. Enter the elevation value that represents the top of the blockage
between the two azimuth limit points in the EL LIMIT 78 parameter. If your ACU software includes 5 volt
polarization you will not see these AZ & EL LIMIT parameters.
CAUTION: The Lower Relative AZ limit is the more counter-clockwise of
the two points (even if it is numerically larger) and the Upper Relative AZ
limit is the more clockwise of the two points. If you enter the two relative
points incorrectly, Tracking and Searching will be adversely affected.

The ACU provides a contact closure to ground on the SW2 terminal of the Terminal Mounting Strip when the antenna
is pointed within any one of the blockage/hazard zones or the system is searching, targeting, unwrapping or is mis-
pointed by 0.5 degrees or more (FCC TX Mute function for Transmit/Receive systems only). The contact closure is a
transistor switch with a current sinking capability of 0.5 Amp. Refer to “Functional Testing” for instructions on how to
simulate a manual BLOCKED condition to test SW2 logic output.
When used as simple “BLOCKED” logic output for a single Sea Tel antenna, this output could be used to light a remote
LED and/or sound a buzzer to alert someone that the antenna is blocked, and therefore signal is lost.
In a “Dual Antenna” installation, this logic output is also used to control a Dual Antenna Arbitrator panel to switch the
TXIF & RXIF signals from Antenna “A” to Antenna “B” when Antenna “A” is blocked, and vice versa.
When used as simple “RF Radiation Hazard” logic output for a single Sea Tel TXRX antenna, this output could be
used to suppress RF transmissions while the antenna is pointed where people would be harmed by the transmitted
microwave RF power output. The SW2 output would be interfaced to the satellite modem to disable the TX output
signal from the Satellite TXRX Modem whenever the antenna is within the RF Radiation Hazard zone(s).

11-1
5009-17 Installation Manual Setup – Blockage & RF Radiation Hazard Zones

When used for “FCC TX Mute” logic output for a single Sea Tel TXRX antenna, this output is used to suppress RF
transmissions whenever the antenna is mis-pointed 0.5 degrees or more, is blocked, searching, targeting or
unwrapping. The SW2 output would be interfaced to the satellite modem to disable/mute the TX output signal from
the Satellite TXRX Modem. When the mute condition is due to antenna mis-pointing, it will not un-mute until the
pointing error of the antenna is within 0.2 degrees. The default output is contact closure to ground when the antenna
is mis-pointed, therefore providing a ground to “Mute” the satellite modem from the SW2 terminal of the Terminal
Mounting Strip. If your satellite modem requires an open to “Mute”, refer to SYSTEM TYPE parameter 16 value to
reverse the output logic from the ACU.
Programming instructions:
Determine the Relative AZ positions where blockage, or RF Radiation Hazard, exists. This may be done by monitoring
the received signal level and the REL display readings while the ship turns or by graphing the expected blockage
pattern. Elevation of the antenna in normal use also must be taken into consideration. A Mast or other structure may
cause blockage at low elevation angles, but may not cause blockage when the antenna is at higher elevation angles
where it is able to look over the structure. Up to four zones may be mapped. Only zones which are needed should be
mapped (in AZ LIMIT pairs).
In unlimited antenna systems the Relative position of the antenna must have been calibrated by properly setting the
Home Flag Offset (HFO) value in the PCU. The HFO calibrates Relative to display 0000 when the antenna is pointed in-
line with the bow of the boat/ship (parallel to the bow).
Convert the relative readings to AZ LIMIT/EL LIMIT values by multiplying by 10. Enter the beginning of the first
blockage region as AZ LIMIT 1 and the end of the region (clockwise direction from AZ LIMIT 1) as AZ LIMIT 2
parameters in the ACU. If needed, repeat setting AZ LIMIT 3 & 4 for a second ZONE and then AZ LIMIT 5 & 6 if a
third ZONE is needed. All unneeded zone AZ LIMIT pairs must be set to 0000. Set the upper elevation limit of each
blockage zone (also entered in degrees multiplied by 10).
EXAMPLE 1 - Three blockage Zones: A ship has a Sea
Tel antenna mounted on the port side and an Inmarsat
antenna mounted on the starboard side. A mast forward, the
Inmarsat antenna to starboard and an engine exhaust stack
aft form the three zones where satellite signal is blocked (as
shown in the graphic). In this example zone 1 is caused by
the mast, zone 2 is from the Inmarsat antenna, zone 3 is
from the stack and zone 4 is not needed:
ZONE 1 begins (AZ LIMIT 1) at 12 degrees Relative
and ends (AZ LIMIT 2) at 18 degrees Relative.
Multiply these Relative positions by 10. Enter AZ
LIMIT 1 value of 0120 and AZ LIMIT 2 value of
0180. In this case the mast height only causes
blockage up to an elevation of 50 degrees, so we
set EL LIMIT 12 to 0500. If the antenna is between
these two AZ Limit points but the elevation is
greater than 50 degrees, the antenna will no longer
be blocked.
ZONE 2 begins (AZ LIMIT 3) at 82 degrees Relative
and ends (AZ LIMIT 4) at 106 degrees Relative.
Multiply these Relative positions by 10. Enter AZ
LIMIT 3 value of 0820 and AZ LIMIT 4 value of 1060. In this case the Inmarsat antenna height only causes
blockage up to an elevation of 12 degrees, so we set EL LIMIT 34 to 0120. If the antenna is between these
two AZ Limit points but the elevation is greater than 12 degrees, the antenna will no longer be blocked.
ZONE 3 begins (AZ LIMIT 5) at 156 degrees Relative and ends (AZ LIMIT 6) at 172 degrees Relative. Multiply
these Relative positions by 10. Enter AZ LIMIT 5 value of 1560 and AZ LIMIT 6 value of 1720. In this case
the stack antenna height only causes blockage up to an elevation of 36 degrees, so we set EL LIMIT 56 to
0360. If the antenna is between these two AZ Limit points but the elevation is greater than 36 degrees, the
antenna will no longer be blocked.
ZONE 4 is not needed. Enter AZ LIMIT 7 value of 0000 and AZ LIMIT 8 value of 0000. Set EL LIMIT 78 to
0000. If your ACU software includes 5 volt polarization you will not see these AZ & EL LIMIT parameters.

EXAMPLE 2 - Three blockage Zones, Dual Antenna

configuration: A ship has 2 Sea Tel antennas, “Antenna
A” mounted on the port side and “Antenna B” mounted on
the starboard side. Antenna A is designated as the master
antenna and its zones would be set as in example 1 above.
The mast forward, Antenna A to port and the engine
exhaust stack aft form the three zones where satellite
signal is blocked from Antenna B. The SW2 logic output
from Antenna A (ACU A) and Antenna B (ACU B) are used
to control a “Dual Antenna Arbitrator”, which will route
satellite signal from the un-blocked antenna to the other
below decks equipment. If both antennas are tracking the
same satellite, they will not both be blocked at the same
time. The logic output will switch to provide satellite signal
to the below decks equipment from Antenna A when it is
not blocked and will switch to provide satellite signal
from Antenna B whenever Antenna A is blocked. The
switches will not change state if both antennas are
blocked, or if both are on satellite.
Antenna A is the same as the previous example and
its ACU would be set to those AZ LIMIT values.
Antenna B ACU would be set to:
In this example Antenna B zone 1 is caused by the stack, zone 2 is from Antenna A, zone 3 is from the mast and zone
4 is not needed.
ZONE 1 begins (AZ LIMIT 1) at 188 degrees Relative and ends (AZ LIMIT 2) at 204 degrees Relative. Multiply
these Relative positions by 10. Enter AZ LIMIT 1 value of 1880 and AZ LIMIT 2 value of 2040. In this case
the stack height only causes blockage up to an elevation of 42 degrees, so we set EL LIMIT 12 to 0420. If the
antenna is between these two AZ Limit points but the elevation is greater than 42 degrees, the antenna will
no longer be blocked.
ZONE 2 begins (AZ LIMIT 3) at 254 degrees Relative and ends (AZ LIMIT 4) at 278 degrees Relative. Multiply
these Relative positions by 10. Enter AZ LIMIT 3 value of 2540 and AZ LIMIT 4 value of 2780. In this case
the Antenna B height only causes blockage up to an elevation of 12 degrees, so we set EL LIMIT 34 to 0120.
If the antenna is between these two AZ Limit points but the elevation is greater than 12 degrees, the antenna
will no longer be blocked.
ZONE 3 begins (AZ LIMIT 5) at 342 degrees Relative and ends (AZ LIMIT 6) at 348 degrees Relative. Multiply
these Relative positions by 10. Enter AZ LIMIT 5 value of 3420 and AZ LIMIT 6 value of 3480. In this case
the mast height only causes blockage up to an elevation of 41 degrees, so we set EL LIMIT 56 to 0410. If the
antenna is between these two AZ Limit points but the elevation is greater than 12 degrees, the antenna will
no longer be blocked.
ZONE 4 is not needed. Enter AZ LIMIT 7 value of 0000 and AZ LIMIT 8 value of 0000. Set EL LIMIT 78 to
0000. If your ACU software includes 5 volt polarization you will not see these AZ & EL LIMIT parameters.

EXAMPLE 3 - One blockage Zone: A ship has a Sea Tel antenna mounted on the center line of the ship. A mast is
forward and an engine exhaust stack is aft. In this example the
Stack does NOT block the satellite, only the mast forward
does. In this example zone 1 is caused by the mast, zone 2, 3
and 4 are not needed:
ZONE 1 begins (AZ LIMIT 1) at 352 degrees Relative
and ends (AZ LIMIT 2) at 8 degrees Relative. Multiply
these Relative positions by 10. Enter AZ LIMIT 1
value of 3520 and AZ LIMIT 2 value of 0080. In this
case the mast height only causes blockage up to an
elevation of 52 degrees, so we set EL LIMIT 12 to
0520. If the antenna is between these two AZ Limit
points but the elevation is greater than 52 degrees,
the antenna will no longer be blocked.
ZONE 2 is not needed. Enter AZ LIMIT 3 value of
0000 and AZ LIMIT 4 value of 0000. Set EL LIMIT 34
to 0000.
ZONE 3 is not needed. Enter AZ LIMIT 5 value of
0000 and AZ LIMIT 6 value of 0000. Set EL LIMIT 56
to 0000.
ZONE 4 is not needed. Enter AZ LIMIT 7 value of
0000 and AZ LIMIT 8 value of 0000. Set EL LIMIT 78 to 0000. If your ACU software includes 5 volt
polarization you will not see these AZ & EL LIMIT parameters.
EXAMPLE 4 - Overlaid Blockage Zones: A ship has a
Sea Tel antenna mounted on the center line of the ship. A
mast mounted on top of a deckhouse (like the picture
below) is forward and an engine exhaust stack, also on a
deckhouse, is aft. These two blockage areas have wide
azimuth blockage at lower elevations and then a narrower
azimuth area of blockage extends up to a higher value of
elevation.
ZONE 1 begins (AZ LIMIT 1) at 334 degrees
Relative and ends (AZ LIMIT 2) at 026 degrees
Relative. Multiply these Relative positions by 10.
Enter AZ LIMIT 1 value of 3340 and AZ LIMIT 2
value of 0260. In this case the mast height only
causes blockage up to an elevation of 40 degrees,
so we set EL LIMIT 12 to 0400. If the antenna is
between these two AZ Limit points but the
elevation is greater than 40 degrees, the antenna
will no longer be blocked.
ZONE 2 begins (AZ LIMIT 3) at 352 degrees
Relative and ends (AZ LIMIT 4) at 008 degrees
Relative. Multiply these Relative positions by 10.
Enter AZ LIMIT 3 value of 3520 and AZ LIMIT 4
value of 0080. In this case the mast height only
causes blockage up to an elevation of 70 degrees,
so we set EL LIMIT 34 to 0700. If the antenna is
between these two AZ Limit points but the
elevation is greater than 70 degrees, the antenna
will no longer be blocked.

ZONE 3 begins (AZ LIMIT 5) at 155 degrees

Relative and ends (AZ LIMIT 6) at 205 degrees
Relative. Multiply these Relative positions by 10.
Enter AZ LIMIT 5 value of 1550 and AZ LIMIT 6
value of 2050. In this case the mast height only
causes blockage up to an elevation of 30 degrees,
so we set EL LIMIT 56 to 0300. If the antenna is
between these two AZ Limit points but the
elevation is greater than 30 degrees, the antenna
will no longer be blocked.
ZONE 4 begins (AZ LIMIT 7) at 173 degrees
Relative and ends (AZ LIMIT 8) at 187 degrees
Relative. Multiply these Relative positions by 10.
Enter AZ LIMIT 7 value of 1730 and AZ LIMIT 8
value of 1870. In this case the mast height only causes blockage up to an elevation of 55 degrees, so we set
EL LIMIT 78 to 0550. If the antenna is between these two AZ Limit points but the elevation is greater than
55 degrees, the antenna will no longer be blocked. If your ACU software includes 5 volt polarization you will
not see these AZ & EL LIMIT parameters.

12. Setup – Modem Connections, Setup and Test

In order to be compliant with FCC Order 04-286 and WRC-03 Resolution 902 the Satellite Modem MUST be connected to the
Antenna control Unit/Terminal Mounting Strip to provide TX Mute control functionality. The FCC/WARC requirements have
been adopted by ITU & ETSI for them to publish similar requirements. The current FCC/WARC requirements are:
• Mute the Transmit output of the Satellite Modem used in TX/RX antenna configurations when the antenna is
positioned where people may be harmed by the transmit power emanating from the antenna (RF Radiation
Hazard).
• Mute the Transmit output of the Satellite Modem used in TX/RX antenna configurations when the antenna is
mispointed by 0.5 degrees, or more, and keep it muted until the antenna is within 0.2 degrees of peak pointing to
the satellite for a minimum of 5 seconds (FCC part 25.221 & 25.222 TX Mute requirement).
The connection will also provide External Modem Lock and GPS Latitude & Longitude.
The External Modem Lock output from a satellite modem into the ACU provides a positive Network ID input to the ACU when
the antenna is on the desired satellite. This input is NOT used for Tracking purposes, it is only used for satellite
identification to assure that the satellite which has been acquired is the correct satellite (else the ACU will resume searching).
The GPS output from the ACU provides the current ships Latitude & Longitude as an input to the satellite modem for mobile
mode operation.
All modems must be set for mobile operation and have hardware handshaking turned ON.

12.1. iDirect Modems

The 5100 mobile mode can be set to 1=Serial to use the Console port RJ-45 serial connector or 2=Ethernet to use a
LAN connector for TX Mute, Modem Lock and GPS position communication with the ACU.

Model Lock output Mute input Recommended GPS Input

SYSTEM TYPE
Infinity 3100 LOW = Lock HIGH to Mute 23 GGA string
Infinity 5100 LOW = Lock HIGH to Mute 23 GGA string

Note 1: The option file MUST have Mobile Mode and Hardware Handshaking ON.
Note 2: JP4 on the Terminal Mounting Strip MUST be removed when using iDirect 3000 & 5000 Series
Modems.

12.4. Connections (ACU to Satellite Modem)

12.4.1. iDirect Modems

Infinity 3100 - Use an RJ-45 straight serial cable connected from the
Terminal Mounting Strip “Console Port” connector to the Console
Port connector on the rear panel of the modem.
Infinity 5100 - Use an RJ-45 straight serial cable connected from the
Terminal Mounting Strip “Console Port” connector to the Console
Port connector on the rear panel of the modem.
Note: JP4 on the Terminal Mounting Strip MUST be removed
when using iDirect 3000 & 5000 Series Modems.

12.4.2. Comtech Modems

Connect the 126877 harness assembly from the 15 pin serial port on
the 570L or 600L modem to the Terminal Mounting Strip screw
terminals.
1. Assure that a jumper is installed at JP4 on the Terminal
Mounting Strip.
2. Cut the resistor/Yellow wire off of the pin on the White wire
(do NOT cut the pin off of the white wire).
3. Connect the pin on the Black & Green wire to the GND
terminal of the Terminal Mounting Strip.
4. Connect the pin on the Red wire to the SW2 terminal of the
Terminal Mounting Strip.
5. Connect the pin on the White wire to the EXT AGC terminal
of the Terminal Mounting Strip.

12.4.3. Hughes Modems

A serial cable (Hughes drawing 1502273) should be provided with the modem. Connect the 15 pin to the
serial port on the HX-150 or HX-200 modem and the RJ-45 connector to the Terminal Mounting Strip
“Console Port”. Refer to instructions from your service provider for specific setting requirements.

12.5. SYSTEM TYPE parameter

The System Type parameter is used to enable a variety of system functions. The defaults in the DAC software
are:
• External AGC, or Modem Lock, function is used to bring an external modem lock signal from a satellite
modem into the ACU as a positive ID that the antenna is on the desired satellite. This input is NOT used for
Tracking purposes, it is only used during search to identify when the antenna has acquired the correct
satellite. Default external AGC function in the DAC software is disabled. Expected input is 0 VDC when the
modem has RX sync/Network Lock and a positive voltage (+15 VDC max) when the does not have lock.
• LNB Voltage - This function enables the Tracking Receiver to output 13/18 VDC to power an LNB or control a
Matrix Switch. Default for this function is OFF.
• The blockage output of the ACU is an open circuit when the antenna is not in a programmed blockage zone,
is not searching, is not targeting and is not mis-pointed by 0.5 degrees. Whenever one of these conditions
exist a transistor on the main PCB in the ACU shorts to ground providing a current sink of 0.5 amps max to
control below decks dual antenna coax switches or TX Mute control to a satellite modem (for radiation
hazard control or TX mute requirements for FCC compliance).
• Relative Azimuth value is normally only visible in the Antenna main menu display. The Azimuth entry menu
normally displays Azimuth position, DishScan tracking signal and AGC.
• When Search limit is reached the antenna will return back to the origin of the search pattern.
• When the ACU power is turned ON it does not automatically target the satellite that was used last.
• Pressing RESET on the front panel of the ACU normally only resets the processors inside but does not re-
target the satellite.
12-2
Setup – Modem Connections, Setup and Test 5009-17 Installation Manual

The functions below can be enabled to change the normal behavior of the system if desired. Select system options
according to the following table. Add together all the desired options and enter the sum into the SYSTEM TYPE
parameter to enable the desired functions.

128 Reverse External Modem Lock input polarity (logic hi = lock).

If you know that the modem you will be using with the system provides requires a logic hi (+15 VDC
max) when it has modem lock or you find the AGC reading for locked and unlocked conditions from
your modem need to be reversed you must enable this function in your current SYSTEM TYPE
parameter.
64 Enables LNB voltage output from the ACU.
This is NOT recommended for Series 09 systems, because they ALL provide the LNB voltage at the
pedestal.
32 Display Relative in the Azimuth entry display.
Enabling this function causes REL position to take the place of the DishScan signaling in the Azimuth
entry display. Relative position of the antenna is RARELY more desirable than the DishScan
signaling.
16 Reverse blockage output logic (SW2 logic hi = blocked).
If you know that the modem you will be using with the system requires a logic hi (open circuit) to
mute or you find that the Modem is being muted when the antenna is ON satellite (and un-muted
when the antenna is blocked, searching or targeting) you must enable this function in your current
SYSTEM TYPE parameter.
8 -- Reserved --
4 Auto SAT load after SEARCH failure.
Enabling this function will cause the ACU to re-target the calculated satellite position (rather
than returning to origin).
2 Enable External Modem Lock Input (logic low = lock)
This enables the ACU to use the external modem input. Expected input is logic low (0 VDC) when
the modem has RX sync/Network Lock and a positive voltage (+15 VDC max) when the does not
have lock. This function must be enabled to use the external input from ANY modem,
regardless of its locked/unlocked logic. [If you find the AGC reading for locked and unlocked
conditions need to be reversed you must add 128 to your current SYSTEM TYPE parameter].
1 Auto SAT load on “hot” RESET and ACU Power-Up.
Enable this function if you want the ACU to automatically re-target the satellite whenever the
system power is turned ON (after antenna initialization) or whenever the operator presses the
RESET button on the from panel of the ACU.

To change the SYSTEM TYPE parameter, press the LEFT arrow key to bring the cursor under the least significant
character. Continue to move the cursor until the desired character to be edited is underscored (selected). Use the UP
or DOWN arrow keys to increment or decrement the selected character. Use the LEFT or RIGHT arrow key to move
the cursor left or right to select other characters to modify. When you are finished modifying press ENTER to execute
the new value Continue pressing ENTER until SAVE NEW PARAMETERS is displayed, and then press the RIGHT
arrow, UP arrow then ENTER to save the change(s).

12.6. Blockage Simulation Test

Blockage output function is used to modify the behavior of Tracking and Searching when there is a known blockage
zone. The ACU provides a contact closure to ground on the SW2 terminal of the Terminal Mounting Strip when the
antenna is pointed within any one of the blockage/hazard zones or the system is searching, targeting, unwrapping or is
mis-pointed by 0.5 degrees or more (FCC TX Mute function for Transmit/Receive systems only). The contact closure
is a transistor switch with a current sinking capability of 0.5 Amp. This logic output control signal is used for:
• When used as simple “BLOCKED” logic output for a single Sea Tel antenna, this output could be used to light a
remote LED and/or sound a buzzer to alert someone that the antenna is blocked, and signal is lost.
• In a “Dual Antenna” installation, this logic output(s) is used to control Dual Antenna Arbitrator panel of coax
switches to switch the source inputs to the matrix switch from Antenna “A” to Antenna “B”, and vice versa.
• When used as simple “RF Radiation Hazard” logic output for a single Sea Tel TX/RX antenna, this output
12-3
5009-17 Installation Manual Setup – Modem Connections, Setup and Test

could be used to suppress RF transmissions while the antenna is pointed where people would be harmed by
the transmitted microwave RF power output. The SW2 output would be interfaced to the satellite modem to
disable the TX output signal from the Satellite TXRX Modem whenever the antenna is within the RF
Radiation Hazard zone(s).
• When used for “FCC TX Mute” logic output for a single Sea Tel TX/RX antenna, this output could be used to
suppress RF transmissions whenever the antenna is mis-pointed 0.5 degrees or more, is blocked, searching,
targeting or unwrapping. The SW2 output would be interfaced to the satellite modem to disable/mute the
TX output signal from the Satellite TX/RX Modem. When the mute condition is due to antenna mis-pointing,
it will not un-mute until the pointing error of the antenna is within 0.2 degrees. The default output is
contact closure to ground when the antenna is mis-pointed, therefore provides a ground to “Mute” the
satellite modem on the SW2 terminal of the Terminal Mounting Strip. If your satellite modem requires an
open to “Mute”, refer to SYSTEM TYPE parameter 16 value to reverse the output logic from the ACU.
To Test the blockage function:
1. Press the NEXT key until you are at the Status menu. (Sea Tel – Remote and antenna software display)
Press ENTER to access the Tracking menu.
2. Press the RIGHT arrow key to bring up and move the cursor to the far right. Press the UP arrow to simulate a
manual BLOCKED condition. BLOCKED will appear in the Tracking display.
3. Verify that SW2 terminal shorts to ground (or open circuit if you have SYSTEM TYPE configured to reverse
the output logic). If the antenna is on the desired satellite and you have RX Synch, also verify that the
Satellite Modem TX is disabled/muted (TX LED OFF).
4. Press the LEFT arrow key and then press the UP arrow key to turn the simulated blocked condition OFF.
BLOCKED will disappear, leaving the ON/OFF Tracking status and the band selection in the Tracking display.
Press the UP arrow key again if you wish to toggle the Tracking state.
5. Verify that SW2 terminal is open circuit (or ground if you have logic reversed). If the antenna is on the
desired satellite and you have RX Synch, also verify that the Satellite Modem TX is enabled (TX LED ON).

12.7. Testing the Satellite Modem Lock (Network ID) Input in the ACU
The input connections from the modem can be tested by selecting the external AGC input and monitoring the
displayed value. To test the external AGC, set the tuning frequency to 0000. Normally, AGC readings below 800 are
considered a low condition and indicate modem lock and AGC readings above 800 are considered a high condition
and indicate modem unlock.
1. Verify that the satellite modem currently has RX Sync (RX Sync LED ON).
2. Turn tracking OFF so that the antenna stays pointed ON satellite.
3. Press NEXT until the Satellite menu is displayed. Press ENTER 3 times to display the Frequency entry
window. Record the frequency that the tracking receiver is currently tuned to. Press LEFT or RIGHT arrow
key to bring up the cursor under the units digit Use the UP or DOWN arrow keys to increment or decrement
the selected digit, use the LEFT arrow key and the UP or DOWN arrow keys to change the next digit.
Continue until frequency is set to 0000. Press the ENTER key to tune the tracking receiver to this frequency.
4. View current ON satellite LOCKED AGC value in the lower right corner of the display and measure the DC
Voltage from EXT AGC (+) terminal to the GND (-) terminal. The iDirect & Comtech modems should have an
AGC readings below 800 (LOCK = low condition) and 0 VDC across the EXT AGC and GND terminals. The
Hughes modem will have an AGC reading above 800 (LOCK = high condition) and 12VDC across the EXT AGC
and GND terminals.
5. Disconnect the RXIF input coax from the rear of the satellite modem. It should lose RX Synch (RX Synch LED
OFF).
6. View current ON satellite UN-LOCKED AGC value in the lower right corner of the display and measure the
DC Voltage from EXT AGC (+) terminal to the GND (-) terminal. The iDirect & Comtech modems should have
an AGC readings above 800 (UN-LOCKED = high condition) and about +12 VDC across the EXT AGC and GND
terminals. The Hughes modem will have an AGC reading below 800 (UN-LOCKED = low condition) and
12VDC across the EXT AGC and GND terminals.
7. Reconnect the RXIF input coax to the rear of the satellite modem. It should regain RX Sync (RX Sync LED
ON).
8. Press LEFT or RIGHT arrow key to bring the up the cursor under the units digit Use the UP or DOWN arrow
keys to increment or decrement the selected digit, use the LEFT arrow key and the UP or DOWN arrow keys
to change the next digit. Continue until frequency value, recorded in step 3, is displayed and press the
ENTER key to re-tune the tracking receiver.

Setup – Optimizing Polarity & Cross-Pol Isolation 5009-17 Installation Manual

13. Setup – Optimizing Polarity & Cross-Pol Isolation

The only way to optimize the polarization of the antenna properly is to peak the polarity angle while the system is in auto-
polarization mode. This automatically adjusts the polarization of the feed by calculating the required polarization angle for the
feed every 2 seconds based on ship's Latitude, Longitude and the desired Satellite Longitude.

13.1. Sat Skew setting

The Satellite Skew setting in the Satellite – Tracking Receiver sub-menu (prior to NID) is used to enter the skew of the
satellite to optimize polarity angle.
This feature is used in conjunction with POL OFFSET to optimize polarization of the feed. POL OFFSET will serve to
calibrate the feed itself (mechanical calibration) Before adjusting the SKEW parameter, target a satellite that is of your
same longitudinal position (ie from Concord, CA at 38N and 122W we would target a satellite value of 122W). Drive
the reflector to 0 or 5 degrees elevation (this is so you can easily view the feed). And verify that the feed is a pure
vertical. This may be visually verified by placing a level bubble on the LNB itself. During Cross-Pol isolation tests, enter
in the known skew value of the satellite, then as instructed by the NOC to drive the feed assembly, increase or
decrease the SAT SKEW parameter. Each digit represented on this screen represents one whole degree of feed drive.

13.2. Polarity Angle (POLANG) Parameters

First of all make sure that the polang parameters are set correctly:
1. POL TYPE – should be set to 0072 (Auto-Pol mode).
2. POL OFFSET – This is initially set to factory default (0040) but will be incremented, or decremented, to
calibrate the feed to the horizon with a level (bubble or digital).
3. POL SCALE – Leave this at the factory default setting of 0090.
4. Go to the TX POLARITY parameter in the Setup menu of the ACU and set this parameter to your assigned
Transmit polarity (2=Horizontal or 4=Vertical).
5. Target your desired satellite (as provided by you airtime provider).
6. Verify the system has acquired the correct satellite, else continue searching until the correct satellite is
acquired, and set your satellite modem (or spectrum analyzer) to view its signal level display.
7. Allow tracking to peak the satellite signal.
8. SAT SKEW – This setting will be incremented, or decremented, to optimize the polarity to peak the received
satellite signal, and later to do cross-pol isolation with the airtime provider, network operation center or
satellite provider.

13.3. Optimizing Auto-Polarization on Receive Signal

This procedure optimizes the linear polarization of the feed based on the received signal level.
1. Verify that tracking is ON and that the antenna is peaked on your targeted satellite (targeting calculates the
azimuth, elevation and polarization angles).
2. Go to the SAT SKEW parameter in the Satellite menu of the ACU. Default setting is 0000 and may be
incremented, or decremented, to adjust polarization while in Auto-Pol mode. Each increment equals one
degree of polarization rotation, decrement below 0000 for minus polarization.
3. Press the RIGHT arrow to edit the current value.
4. While watching the modems signal strength, the ACUs AGC value, or the spectrum analyzer satellite signal
level, press the UP arrow to increment or the DOWN arrow to decrement the value and then hit the ENTER
key to adjust the feed to the new value. Allow 10 seconds between increments or decrements to allow time
for feed assembly to drive to new position.
5. Press the RIGHT key again, make another small change in the same direction and hit ENTER to carry out the
adjustment.
6. Repeat this process of making small adjustments in the same direction until you see the modem signal
strength, ACUs AGC value, or the spectrum analyzer satellite signal level decrease a noticeable amount (10
counts on the signal strength, 10 counts of AGC or ½ dB of signal level).
7. Note the SAT SKEW value.

13-1
5009-17 Installation Manual Setup – Optimizing Polarity & Cross-Pol Isolation

8. Make a series of small changes in the opposite direction until you see the signal peak and then fall the same
amount as noted in step 6.
9. Note this SAT SKEW value.
10. Set SAT SKEW to mid way between the value noted in step 7 & 9.
11. Save your new SAT SKEW value.

13.4. Optimizing Auto-Polarization Cross-Pol Isolation

During commissioning, under guidance from the network operation center, you will be adjusting to minimize the effect
of your transmission on the opposite polarization which maximizes your Cross-Pol isolation. Contact your satellite
provider to help you (over the phone) to optimize the polarity angle for maximum Cross-Pol isolation (this optimizes
your transmit polarity and is much more accurate than trying to optimize your receive polarity).
1. Verify that tracking is ON and that the antenna is peaked on your targeted satellite (targeting calculates the
azimuth, elevation and polarization angles).
2. Follow your service provider technicians instructions to set the modem to begin transmitting a CW (pure
carrier) signal.
3. Go to the SAT SKEW parameter in the Satellite menu of the ACU.
4. Press the LEFT arrow to edit the current value.
5. While under direction of the technician (on the phone), press the UP arrow to increment or the DOWN arrow
to decrement the value and then hit the ENTER key to adjust the feed.
6. The technician should indicate whether the adjustment you made improved, or worsened, the cross-pol
isolation. If it improved he will have you make another small adjustment in the same direction. If it
worsened he will have you make a small adjustment in the opposite direction.
7. Press the RIGHT key again, make the next change as directed and hit ENTER to carry out the adjustment.
8. Repeat this process of making small adjustments until the technician confirms that cross-pol isolation is
optimized.
9. Save your new SAT SKEW value.

14.4. REMOTE COMMAND

This parameter was used to issue diagnostic commands to the PCU, but is superseded by the use of DacRemP
diagnostic software that your dealer will use when necessary.

14.5. REMOTE MONITOR

This parameter was used to monitor the results of a diagnostic command which was sent to the PCU.

14.6. To Disable/Enable DishScan

When running a beam pattern test, a programmed sweep for NOC/Satellite Operator, balancing the antenna or
motor diagnostics where you want the drives (AZ, EL & CL) not to be oscillating you will have to disable DishScan.
Select the DISHSCAN parameter window on the ACU:
1. Press the RIGHT arrow, then press the UP arrow and last press the ENTER key to turn DishScan mode ON.
2. Press the RIGHT arrow, then press the DOWN arrow and last press the ENTER key to turn DishScan Mode
OFF.
If you change this remote parameter, you must save the change using REMOTE PARAMETERS.
If DishScan is OFF and the Step Integral parameter is set to 0000, you will get a constant ERROR 0016 (DishScan error)
and you will see zeros flashing in the lower left of the Azimuth and Elevation ENTRY menu displays. This is a visual
indication that DishScan is turned OFF.
Always assure that you turn DishScan back ON when returning to normal operation.

14.7. Satellite Reference Mode

The ships gyro compass input to the ACU may be accurate and stable in static conditions and yet may NOT be

14-1
5009-17 Installation Manual Setup – Other Parameters

accurate or stable enough in some underway dynamic conditions. If there is no gyro compass or if the input is corrupt,
not stable or not consistently accurate the tracking errors will become large enough to cause the antenna to be mis-
pointed off satellite.
Satellite Reference Mode will uncouple the gyro reference from the azimuth rate sensor control loop. When operating
in Satellite Reference Mode changes in ships gyro reading will not directly affect the azimuth control loop. The
Pedestal Control Unit will stabilize the antenna based entirely on the azimuth rate sensor loop and the tracking
information from DishScan. This will keep the azimuth rate sensor position from eventually drifting away at a rate
faster than the tracking loop can correct by using the tracking errors to regulate the rate sensor bias.
Satellite Reference Mode can be used as a diagnostic mode to determine if tracking errors are caused by faulty gyro
inputs.
Satellite Reference Mode MUST be used when:
• No Gyro Compass is available
• Frequent or constant ACU Error Code 0001 (Gyro Compass has failed)
• Gyro Compass output is NMEA heading
• Flux Gate Compass is being used
• GPS Satellite Compass is being used
To view, or change, the Satellite Reference Mode status, select the SAT REF remote parameter:
1. Press the RIGHT arrow, then press the UP arrow and last press the ENTER key to turn Satellite Reference Mode
ON.
2. Press the RIGHT arrow, then press the DOWN arrow and last press the ENTER key to turn Satellite Reference
Mode OFF.
If you change this remote parameter, you must save the change using REMOTE PARAMETERS.

Wind: Withstand relative average winds up to 56 m/sec (125 mph) from
any direction.
Ingress Protection Rating All Sea Tel radomes have an IP rating of 56
Cable Passage - The radome base is designed with a bottom center cable passage and Roxtec® Multidiameter®
blocks for cable strain relief. Bottom center cable passage is recommended, however, a strain relief kit is provided with
the system if off-center cable entry is required. Note: Strain relief installation procedure MUST be followed to
assure that the cored holes are properly sealed to prevent moisture absorption and de-lamination of the radome
base.
Maintenance – The radome must be kept clean and free of residues that will increase the RF attenuation.
Repair - NOTE: Damage to the seal of the inside, or outside, of the radome can allow moisture to be absorbed. This
will result in de-lamination of the radome, increased weight and higher attenuation.
To maintain the RF transparency characteristics of the radome top, any cracks, scratches or other damage to the
surface seal of the tuned radome top must be repaired and re-sealed by a competent “A” layered laminate, or cored
deck, repair professional.
Cracks in, or other damage to, the radome base can be repaired using typical fiberglass repair techniques and proper
sealing of the inside and outside surfaces. Edges of holes in the radome base must be properly sealed to prevent
moisture from being absorbed into the layered construction of the radome base.
Disposal - Should it ever become necessary to dispose of the radome, it must be disposed of using the same
handling procedures as other fiberglass materials.

 Procedure, Radome Strain Relief Installation

1.0 Purpose. To define the installation procedure for installing strain reliefs in “smooth base”
radomes.
2.0 Scope. This installation procedure applies to fiberglass radomes having Sea Tel’s standard
four-hole mounting pattern, and M12 mounting hardware, in the 80-180 cm (34-66 in)
nominal size range, typically referred to as “smooth” base radomes. It also applies to our
larger 193 cm (76-inch) radome having a twelve-hole mounting pattern. It is to be used where
the preferred center cable exit may not be desired.
3.0 Tools/materials.
1. Electric drill.
2. Small drill bit 1/8” dia. (3-4mm dia.).
3. Hole saw, 1 3/8” dia. (35 mm), with mandrel and ¼” dia. pilot drill.
4. Medium file.
5. Two 1-1/2” (38 mm) adjustable pliers.
6. #2 Phillips screwdriver.
7. Fiberglass resin & catalyst, (marine grade) - at least 2 oz (50 cc).
Such as Tap Plastics Marine Vinyl Ester Resin with MEKP Catalyst.
Note: Use liquid resin, instead of paste type, due to better penetration.
8. Mixing cup – 4 oz (100 cc).
9. Disposable brush.
10. Strain Relief Assembly 124903-1, (one per cable).
4.0 Responsibilities. It is the responsibility of the installer to observe all standard safety
precautions, including eye, slip, and chemical protection when performing this procedure.
4.1 Procedure.
Remove the standard cable pass through assembly 130818-1*
* N/A for 193 cm (76-inch) nominal size radomes. Refer to Fig 1, then use #2 Phillips
screwdriver to remove 4 ea. attachment screws.
Use #2 Phillips
screwdriver to
remove 4 ea.
screws.

 Procedure, Radome Strain Relief Installation

4.2 Making the holes

PLANNING: Space has been allowed for
up to 5 ea. strain reliefs, but, install only A
as many as needed. (Typically only 2-3 B
for TX/RX systems). Refer to Fig 2 then
plan which hole positions to use. C
For 76-inch radomes lowest holes may
be approx 1.5 inches from inside wall
corner with floor (ref drawing 129416).
Note: The hole center-to-center distance
given is the MINIMUM.
E
Follow good engineering practice and
provide the largest spacing possible
between holes as follows: D
1 Hole pattern - "A".
2 Hole pattern - "B", "C".
3 Hole pattern - "A", "B", "C", ("A", "D", "E" PERMITTED). Fig. 2 – Planning
4 Hole pattern - "B", "C", "D", "E". Measure in place or use
5 Hole pattern - “A”, "B", "C", "D", "E". template drawing 132234

 Procedure, Radome Strain Relief Installation

4.3 Measure, mark and drill pilot holes

CAUTION: The hole locations cannot be determined accurately from outside of the radome.
Using full scale drawing 132234, provided in the strain relief kit, measure mark and drill pilot holes from
the inside out, and using only light pressure, use the small drill bit, (~1/8” dia) to make a pilot hole
through each planned location.
4.4 Use the hole saw from the outside with light pressure.
CAUTION: Using the hole saw from the inside is likely to damage the Gel Coat.
CAUTION: Heavy pressure on the hole saw from the inside is likely to damage the Gel Coat and
splinter the fiberglass.
Working from the outside, use a 1-3/8” hole saw to make the holes for the planned strain reliefs.
4.5 After holes are drilled CAREFULLY use a file to clean the hole edges.
4.6 Test fit the strain reliefs in each location, then, make adjustments as
necessary.
4.7 Sealing the hole edges.
CAUTION: Cut edges can allow water and/or ice ingress and weaken the fiberglass laminate or
structural foam. It is essential to seal all cut edges thoroughly with fiberglass resin to preserve the
radome’s structural strength.
CAUTION: Fiberglass paste or RTV silicone sealant will not wick into and seal the fiberglass strands as
well as fiberglass resin, ONLY use fiberglass resin (such as TAP PLASTICS MARINE VINYL ESTER,
or equivalent) for sealing the cut edges.
Follow the manufacturer’s instructions to mix a small amount of fiberglass resin and catalyst, then
working quickly, use a disposable brush to apply mixed fiberglass resin to the hole edges, both inside
and out.
Allow the fiberglass resin to set per resin manufacturer’s instructions.
Note: Like all chemical reactions, set time will be temperature/humidity dependent.
4.8 Refer to strain relief assembly drawing 124903
Being careful not to damage either the radome or the strain relief threads, use adjustable pliers to install
strain reliefs.
