Provider’s Site Modems

Service is provided to end users by Solution Providers (SPs) who use the SkyWave
IsatData Pro network to offer particular applications and/or services to their clients. The
SPs link their application services to the satellite units by connecting to the IsatData Pro
gateway. This acts as the communications hub of the system, routing traffic to and from
the modems and the various service providers.
Configuration and data retrieval from the unit can be easily accomplished through
Internet-based application services provided by SPs or by integrating existing customer
enterprise software to receive information from the Gateway.

1.3 Operating Modes

The modem operates in the modes described in Table 1.
Table 1 Operating Modes
Operating Mode Description
Transmit Mode In transmit mode the modem is transmitting a signal to the gateway.
Receive Mode In receive mode the modem is attempting or actively listening to the
satellite (listening on the bulletin board channel or on a traffic
channel).
Sleep Mode This is the power saving mode when the modem turns its main
power off between wake-up intervals. Both the modem and gateway
track the wake-up interval. Consequently, when a modem is in sleep
mode it does not miss incoming messages. If a modem has a
message to send, it automatically exits sleep mode without waiting
for the next wake-up interval.
Idle Mode In this mode the modem is awake, but neither receiving nor
transmitting.

1.3.1 Peripherals
These peripherals are either on or off. Power consumption is affected when they are
powered on.
Table 2 Peripherals
Operating Mode Description
GPS/GLONASS Can be powered on independently of the IsatData Pro receiver.
RS-232 The RS-232 transmit driver is enabled whenever a valid input
RS-232 signal is detected.

3.2.3 Immunity to Power Supply Failure

The modem meets all specifications and does not display any corrupted software or loss
of essential data after being subjected to three 60 s power supply failures per IEC 60945,
section 10.8.

3.2.4 Fast Transient Immunity

The IDP-290 operates normally after being exposed to fast transients per IEC 60945,
section 10.5.

3.2.5 Load Dump Circuitry

The modem's power supply input voltage range is 9 to 32 V. Above this range the load
dump protection circuitry disconnects external power so that the modem is not damaged,
up to 150 V. When the input voltage drops below the threshold, the modem recovers,
going through power on reset.
With this protection, the modem is capable of withstanding load dumps as specified in
SAE J1455 (rev Jun 2006) paragraph 4.13.2.2.1.

3.2.6 Fuse
The modem has an internal 5 A fuse that provides protection in the event of an internal
short on the modem. The internal fuse cannot be reset and is not field repairable.

3.2.7 Inrush Current

Inrush current transients occur when the modem is:
 First powered on.
 Preparing for transmit. This is when the modem switches its internal voltage rail
to a higher voltage for transmitting.
 Modem starts to transmit. This is when the modem's power amplifier is turned
on.

3.4 Serial Interfaces

3.4.1 RS-232
The RS-232 interface defaults to the following settings: 9600 bps, 1 start, 8 data, no
parity and 1 stop bit, and operates in auto-power down mode. The baud rate is
configurable up to 115,200 bps.
The modem remains awake with its internal RS-232 transceiver active whenever the RS-
232 Rx line senses a valid RS-232 input voltage level. To allow the unit to power down
the serial interface and go to sleep, the RS-232 Rx line must be unpowered (hardware
connected to the RS-232 Rx pin must be disconnected or the RS-232 transceiver must be
powered off so that no voltage is applied to this pin).
The electrical characteristics of the interface are:
Parameter Minimum Typical Maximum Units
Serial Rx Input Low Threshold 0.6 - - V
Serial Rx Input High Threshold - - 2.4 V
Serial Tx Low Output - - -3.7 V
(3 k load)
Serial Tx High Output 3.7 - - V
(3 k load)

3.4.1.1 Auto RS-232 Power On/Off

The modem uses the input voltage to turn the RS-232 driver on/off when auto RS-232
mode is selected.
Table 8 Auto RS-232 Power On/Off
Parameter Value
Valid Rx Input Threshold Rx > 2.7 V or Rx < -2.7 V
Invalid Rx -0.3 V < Rx < 0.3 V

3.4.1.2 Force the RS-232 Driver On

If the device connecting to the IDP-280 operates in auto-shutdown mode, the IDP-280's
serial interface can be activated by using an external pull-up resistor on the RS-232 Rx
line to generate a minimum of 2.7 V.
The recommended external resistor values below assume a 3k input worst case resistance,
a minimum input power voltage of 10V for a 12 V system and 20V for a 24V system.
 For a 12 V system, a 7.5k pull-up ensures 2.9 V at the Rx input
 For a 24 V system, an 18k pull-up yields 2.9 V at the Rx input
Note: With an external pull-up, IDP-280's RS-232 drivers are on continuously which
prevents the modem from entering its lowest power modes.

 30 mm diameter hole punch or hole saw (bottom connector version only)

 Screwdriver
 Socket wrench set
SkyWave recommends that the Solution Provider supply the end-user with a custom built
cable.

4.3 Identify the Fuse Panel Location

For installation in a truck, the cable from the modem connects to the truck's fuse panel for
power.
1. Locate the fuse panel in the truck. The location depends on the type, age, and
model of the truck.
2. Identify an un-switched vehicle power source within the fuse panel for modem
power.
3. Ensure that the cable you ordered is of sufficient length to reach from the fuse
panel to the final mounting location of the modem.

4.4 Determine a Suitable Mounting Location

Before installing the modem, consider the important guidelines provided below.
CAUTION It is very important for installers to install the units in a safe and
secure way to avoid danger or damage to persons or property.
 Mount the modem where it has a clear view of the sky/satellite with no obstructions.
For a mobile installation, this means at the highest point on the vehicle or vessel
where it has a clear view of the sky in all directions.
 Mount the modem on a flat surface for mobile installations such that the elevation
angle does not change with rotation.
 Fasten the modem securely so that it is not loose and does not move.
 Mount the modem on a rigid, stable surface. If necessary, use a mounting bracket
(not supplied) or other suitable support.
 Mount the modem so that the top surface is horizontal (flat). Failure to do so might
compromise line of sight between the satellite and the modem.
 Mount the modem on a surface that does not get hotter than the maximum operating
temperature. If the surface might get hotter, mount the modem with a thermal barrier
between it and the mounting surface.
CAUTION Mount the modem at
least 20 cm away from humans.
 Do not mount the modem close to other electrical equipment to prevent possible
radiated and/or conducted electromagnetic interference.
 Do not mount the modem close to radar or other communications antennas. Use the
following guidelines:

© ORBCOMM Proprietary 23 T212, Version 03

IDP-280/IDP-290 - Hardware Guide

> 1 m from VHF/UHF antenna

> 3 m from loop antenna
> 4 m from MF/HF antenna
> 5 m from other satellite antennas
Not within a radar beam
 Do not mount the modem where water might build-up or collect.
 Use non-metallic and non-metallic flake paint above the modem if the installation is
under fiberglass or composite wind fairings.
 Check that the modem's cable reaches the power source before you drill any
mounting holes.
 Do not mount the modem close to an exhaust pipe due to the excessive heat and the
potential for the exhaust pipe blocking satellite signal.
 Mount the modem on the driver's side of the vehicle, if possible, when there is a
possibility of strikes by overhanging tree branches.
When you have selected the mounting location, mount the modem (refer to Section 4.5).

4.5 Route the Main Cable

Consider the following guidelines before routing the cable assembly.
CAUTION Ensure the power cable will not be pinched, kinked or worn
down by any objects or moving parts such as the door hinges. It
is very important to secure the cable at many points along its
path.
CAUTION Prior to working on any cabling, ensure that the modem is
powered off and will not start while work is in progress.
 Do not route the cable near the engine if routing through the engine compartment.
This location can subject the cable to extreme heat.
 Keep the cable away from hot surfaces such as exhaust pipes because this might
damage the cable.
 Do not run the cable over sharp or jagged edges.
 Place the cable in recesses and channels, whenever possible, to prevent potential
damage or wear by foot traffic.
Note: Remember to leave enough cable slack near the modem for strain relief so as
not to introduce any additional force on the connector. SkyWave recommends
securing the cables during installation.

T212, Version 03 24 © ORBCOMM Proprietary

 IDP-280/IDP-290 - Hardware Guide

Figure 21 Sample Cable Placement in a Vehicle Cab

Run the cable assembly following the steps below.

1. Use tape to temporarily secure the modem in its final location while you run the
cable.
CAUTION Do not drill any
mounting holes at
this time.
2. Search for vehicle cab entry points on the side of the vehicle closest to the fuse
panel. This helps to minimize the amount of cable routed along the floor of the
cab.
Where possible route the cable through existing holes in the floor or the firewall
of the engine compartment.
3. Route the cable starting from the modem to the fuse panel or battery source.
Note: SkyWave recommends that you tape cable ends to prevent dirt from collecting
on the contacts.

4.6 Mount the Modem

CAUTION Painting the modem might
interfere with their performance.

The modem either has a bottom connector or a side connector.

The duplicate mobile ID labels, shipped with the modem, can be placed on the asset
where the modem is mounted and/or on any customer paperwork. For outdoor
applications these labels should be protected by applying the clear overlays provided.
Note: The Solution Provider is responsible for providing mounting instructions if the
mounting is to be done using tools or configurations that are different from the
ones described in this document.
Note: It is the installer’s responsibility to comply with local electrical codes.

6. Wipe off any extra lubricant around the connector.

7. Wrap the mating connector with waterproof sealing tape if using the connector in
changing weather conditions.

4.7 Protect the Cables and Cable Connectors

CAUTION Cable management and connector strain relief must be
incorporated in the installation. SkyWave highly recommends
securing the cable at regular intervals along its length as part of
the installation to prevent cable wear and eliminate strain on the
modem connector. Damage to the modem connector interface or
cable might otherwise result leading to hardware failure.
To protect the modem's connector interface, follow the guidelines below:

T212, Version 03 28 © ORBCOMM Proprietary

 IDP-280/IDP-290 - Hardware Guide

 Apply tape around the cable ends to help in routing the cable.
 Secure the cable such that it does not pull on the connector or strain the modem
connector.
 Tie the cable down so that the weight of a vibrating cable does not stress or strain
the connection.
 Tie the cable down using cable ties and tie holders (Figure 27) at 300 to 600 mm
intervals along the cable route to prevent chafing, wear, or strain.
 Secure the cable tie holder with a self-tapping screw (Figure 27) for best holder
retention.
Figure 27 Cable Management

Adhesive cable tie

holder. Apply a self-
tapping screw here
for added strength.

4.8 Connect to Power

CAUTION Apply power only after making ground connection.

CAUTION Before applying power to the modem, make sure that your power
supply’s rated voltage follows the recommended values specified
in Section 2.
CAUTION The installer is responsible for complying with local electrical
codes.
Note: SkyWave recommends that if possible the user wait until the modem is
unblocked (has a full view of the sky) before powering up the modem.
1. Locate the main power input and the ground (GND) wires on the cable breakout.
You can connect the modem ground to ground in the fuse panel or to chassis ground.
To do this, secure the ground wire on the cable assembly to a piece of metal
electrically connected to the vehicle chassis using a sheet metal screw.
2. Ensure that the main power input and ground wires reach the vehicle fuse panel.
If the wires are not long enough, splice similar gauge wire to the main power input
and ground wires so that they reach the fuse panel. Cover any splices with adhesive
lined heat shrink.
3. Connect the ground wire to the grounding point selected in Section 4.3.

© ORBCOMM Proprietary 29 T212, Version 03

IDP-280/IDP-290 - Hardware Guide

4. Connect the main power input wire to the un-switched vehicle power source within
the fuse panel.
5. Loop and secure any excess cabling.
Figure 28 LED Location

LED

If your application requires extended cable lengths, it is necessary to calculate the cable
voltage drop to determine if the modem is receiving at least 9 V (with 1.7 A draw). Large
cable voltage drops might adversely affect modem operation.
Note: Connect only SkyWave approved cables to the modem. Use of other cables
voids the modem warranty.

4.9 Register the Modem

Note: The modem must complete registration to operate.
When you apply power, the modem goes into satellite search mode to acquire the
SkyWave IsatData Pro network. This activity might take a few minutes to complete. If
you experience difficulties, refer to Section 6 for troubleshooting suggestions.
1. When the modem synchronizes itself with the network, it sends a registration
message to the SkyWave IsatData Pro network.
Note: The modem will not register until it has a clear line of sight to the
satellite.
2. The SkyWave IsatData Pro network records the registration message and
forwards the registration message to the user’s application.
The SkyWave IsatData Pro network sends an acknowledgement message over the
satellite to the modem. The modem is now available to send and receive messages.

4.10 Cleaning Instructions

Wash the modem with only mild soap or detergent.

This section provides the information necessary for the Solution Provider to assemble
IDP power/interface cables for the end-user. The solder cup cable connector kit ships
with the modem.
The cable assembly procedures in this section are adequate for most installations. For
particularly harsh environments such as maritime installations, SkyWave recommends
using a cable with molded backfill as per the Blunt Cut cable in APPENDIX D. Please
contact SkyWave if you need recommendations for a cable manufacturer.
Note: It is recommended you choose a raw cable with the following properties:
* The modem accepts input ranges of 9 to 32 VDC. If your application requires
extended cable lengths, it is necessary to calculate the cable voltage drop to
determine if the modem is receiving at least 9 V (with 1.7 A draw). Large cable
voltage drops might adversely affect modem operation.
* Cable jacket and internal conductor installation rated for minimum
temperature range of -40°C to 85°C, and UV compliant where exposure to UV
is expected.
Note: For reliable operation, shield all cables used for power and data connections to
the modem.

5.1 Required Tools and Materials

The following tools and materials are required to build the cable using this method:
 A cable6 appropriate for the modem's environment
 A knife
 A wire stripper
 Solder
 A fine-tip soldering iron
 A flexible high temperature silicone sealant for outdoor exposure

6 Troubleshooting the Modem

The following section contains troubleshooting information for the Solution Provider
(SP) to provide to end users.

6.1 Modem Does Not Register or Report

On application of external power the modem should register with the satellite and send a
report.
Note: The modem must be visible to the satellite to register with the network and
registration normally takes a few minutes.
If the modem fails to register or report:
 Ensure that the modem has a clear line of sight to the satellite. The modem must
operate outdoors and be unobstructed by buildings, forest canopy, and rock cuts.
 Check that no objects or debris are on the antenna (atop the modem) and
blocking transmission.
 Verify with your SP that the modem is assigned to your account and registered
(that it is sending and receiving) and that the SkyWave IsatData Pro network is
operating properly.
 Check the condition of the power cable.
Replace the modem if the earlier checks fail to uncover the problem.
