Service Manual 1.1 Prevention of Accidents

1 General

The descriptions and instructions in this Service Manual are intended as an aid to the trained service
technician to help him carry out repairs on ATLAS DOLOG systems.
This Service Manual contains the service instructions for the ATLAS DOLOG Electronics Unit.
1.1 Prevention of Accidents

Obey the regulations for the prevention of accidents.

There is a danger of touching electrically live parts.
WARNING
Pay attention to the warning notices and other notices on and in the
units.
When the units are being operated in the opened-up state during trouble-shooting, obey the regulations
for the prevention of electrical accidents.
Even after the main power switch in the Indicator has been switched off, the mains power connection
terminals are live as far as the power switch in the operating part.
Cathode ray tubes are operated with HIGH VOLTAGE. After switching off, short-circuit the anode of the
cathode ray tube to ground to remove the dangerous residual charge.
Before exchanging defective components or assemblies, ensure that the ship’s mains is switched off
(switch off the main switch on the ship’s mains distribution board).
Attach a clearly visible warning notice stating that work is being done on the equipment.

1.2 Service Stations Service Manual

1.2 Service Stations

If repair work cannot be carried out, an authorised ATLAS service station should be called in if possible.
Warranty repairs should be done only by service stations authorised by STN ATLAS Elektronik GmbH,
Bremen.
It is urgently recommended that defective printed circuit boards (assemblies), especially those containing
ICs, should be sent for repair to STN ATLAS Elektronik GmbH in Bremen. If, in special cases, printed
circuit boards are to be repaired by the service stations, these service stations must have the appropriate
test devices.
Ships operating in areas where service stations are difficult to reach should carry additional spare parts
on board.

1.3 Notes about Testing and Repair

For all repair work, the following items are required to this Service Manual:
- The corresponding Operating Instructions manual, which contains a section entitled "Maintenance
and Repair on Board".
In addition, note the following:
- Connecting wires which have been disconnected or unsoldered must be labelled immediately so that
they can be reconnected correctly afterwards.
- All screws have metric thread.

1.4 Notes on the Use of the Service Manual

Unless stated otherwise, the contents of this Service Manual apply to all types of DOLOG.

1.5 Notes about Electrostatic Sensitive Devices (MOS Assemblies)

In the Equipment, MOS assemblies are used to some extent. They are indicated by orange printing on
the front strip and/or on the board.
CAUTION
When extending or transporting MOS assemblies, proceed as follows:
- Switch off the equipment
The discharging of electrostatic energy into this kind of component can destroy it completely.
Before you open units or modules and touch or pull out assemblies in the course of repair work or main-
tenance, it is essential that you use an appropriate working place (e.g. Portable Equipment Type 8012,
stock No. 568-5011).
- Spread a conducting mat out at your work-place.
- Connect the mat to a suitable ground conductor.
The 1 MX resistor in the potential equalisation cable must not be removed.
- Put wrist-band on and discharge yourself. To do this, connect the wrist-band to the mat.
- Use only suitable, properly grounded soldering equipment, measuring instruments and test devices.
At mains voltages of AC 220V 50Hz, these should only be operated via a Fault Current Safety Plug,
Stock No. 593-8099.
You can recognise modules and assemblies containing electrostatically sensitive components from the
following markings:
- Reddish-orange printing on the PC board and/or the front strip.
- A label, on the inside of the module cover, on the front strip of the assembly, or on the PC board.
Please ensure that persons not connected to the potential equalisation system do not try to help you or
to touch electronic assemblies.
- Do not touch conducting elements on the MOS-PCB.
- For the transportation of the MOS-PCB the carrying bags provided for this purpose must be used.
The use of highly insulating packing material, such as untreated polystyrene or simple plastic bags,
is prohibited.

2.3.3.1 True Motion Outputs

Description
Each TM channel provides an item of speed information with sign. The two items of information, coordi-
nated with each other, are each made available via a relay contact.
There are eight outputs for the True Motion signal. They are designated by the abbreviations TM 1 to TM
8. Six TM channels can be connected by means of AMP pin-contacts on the Interconnection Board GE
6010 G 220. Two TM channels (TM 6 and TM 8) have their connection on the connector J23 (see also
Table 2.4).

The pulse rate is programmable in pairs as follows:

- channels TM 1 and TM 2: 200, 400, 800, 1000, 2000 pulses/NM
- channels TM 3 and TM 4: 200 up to 2000 pulses/NM programmable in steps of 100 pulses/NM
- channels TM 5 and TM 6: like channels TM 3 and TM 4
- channels TM 7 and TM 8: like channels TM 3 and TM 4
Standard setting: 200 pulses/NM
The desired number of pulses per NM is set by means of the set up procedure PROGMODE. The instruc-
tions about how to effect the setting are given in section 4.5 of this Service Manual.
The following table shows the standard allocation of the true motion output. The allocation can be
changed by means of the set up procedure PROGMODE.
All TM channels output the measurement in the BOTTOM TRACK mode for preference, and in the
WATER TRACK mode if the depth is greater than max. range to approx. 600m, unless the mode has
been set manually.
Via PROGMODE, each pair of these outputs individually can carry the speed information for the longitu-
dinal or transverse direction with the mode BOTTOM TRACK or WATER TRACK.

2.3.3.3 Analogue Output

Description
Each analogue output provides an item of speed information for an analogue display. A sign is coded,
depending on the type of display instrument. The direction of the speed as a function of the current
(voltage) is in relation to the programmed scale. See fig. 2-7 and 2-8, 2-9.
Three outputs are provided:
V 1: (ship’s longitudinal direction)
↔ V 2: (ship’s transverse direction at the bow) and
↔ V 3: (ship’s transverse direction at the stern) in the standard allocation.
Via PROGMODE, each of these outputs individually can carry the speed information for the longitudinal
or transverse direction with the mode BOTTOM TRACK or WATER TRACK.
The connections are effected by means of AMP pin-contacts on the Interconnection Board
GE 6010 G 220.
Each of the three channels can be set to a current output or a voltage output by means of programming-
switches S1, S2 and S3 on the assembly GE 6010 G 207.
Up to five Analogue Display Units AZ 1013 can be connected in the current mode: S1, S2 and S3 open.
For the selected output the Analogue Display Units AZ 1013 must have the same scale, if more than one
are connected.

2.3.5 Serial Interfaces

Description
The serial interfaces are used to transfer all of the values measured in the DOLOG Electronics Cabinet
to external peripheral devices.
These values also include derived quantities, e.g. the distance travelled.
The data set is contained in a telegram. The telegrams are transmitted to the connected peripherals once
per second approximately.
For Firing UP the DOLOG via PROGMODE there is one serial input SI1, that must be connected to the
MASTER AZ 6044 within the DOLOG equipment. Fig. 2-11 gives an overview on the different signal
paths in the GE 6010 with their signal identifications and the signal directions.
Two interfaces are available; they differ both in their hardware and in their telegram structure:
- Interface type 1 for Control/Display Units AZ 6044 and SAE peripherals (radar, track pilot)
- Interface type 2 for the user’s non - SAE units.

2.3.6 Connection of a Rate-of-Turn Gyro (DOLOG 23 only)

Description
The analogue inputs ROT 1 and ROT 2 and the voltage reference output VR + 10/VR 0 V are used for
connection of the rate-of-turn gyro and the latitude correction switch.
The ROT 1 input must be used in combination with approved Rate-of-Turn equipment with low zero drift.
The rate-of-turn gyro supplies a voltage signal, corresponding to the angular velocity, to the input ROT 1.
Via the analogue input ROT 2, a signal for correction of the geographical latitude error can be obtained
by means of a switch. The correction voltage is produced by division of the reference voltage and is a
measure of the geographical latitude. Via PROGMODE the ROT 1 input can be changed to a suitable
output range of the ROT. The standard allocation is: ± 30°/min ± 10V.

Data of the Analogue Inputs ROT 1, ROT 2

- Input : Symmetrical
- Range : ± 10V max.
- Accuracy : 0.5% ± 0.05% of the full scale value
- Input resistance : 200 k Ω
- Overvoltage : ± 30 V max.
- Range of ROT 1 : (rate-of-turn gyro)

Description
For the BSH-approved echosounders ATLAS ECHOGRAPH 461 with echo logic or ECHOGRAPH 481, a
connection facility is provided for the input of depth information to the DOLOG.
The Electronics Cabinet measures the time between the beginning of the START pulse, which occurs in
synchronism with the transmission pulse, and the beginning of the STOP pulse, which is generated by
the bottom echo.
For the DOLOG, the START pulses are an indication of whether an echosounder is connected and
switched on.
If no bottom echo follows the START-pulse within the sounding range, or if acoustic disturbances are
present and are masking the bottom echo, the display line for depth (SAIL 2) shows dashed lines.
If no echosounder is connected or if the echosounder is switched off, the display line for depth (SAIL 2)
is blanked out.

3 Functional Description

3.1 General Information

Doppler log systems fulfil with great precision and reliability the requirements which have to be met by a
ship’s log when measuring speed at sea, in harbours and on rivers. The speeds which can be measured
range from a few hundredths of a knot to thirty knots; in addition, the speed astern can be measured up
to five knots. The measurement and display of the speed astern is an advantage which most conventional
logs do not offer.
Depending on the version of the Doppler log system, the speed can be measured in
- the ship’s longitudinal direction
- the ship’s transverse direction at the bow
- the ship’s transverse direction at the stern.
The accuracy of measurement is the same for the more complex versions as it is for the one-dimensional
version. As the speed can be measured relative to the bottom at depths up to about 600 m along each
of the axes covered by the version concerned, the Doppler log systems are particularly suitable for
docking, anchoring, mooring, manoeuvring etc., and thus offer the ship’s command personnel advantages
that were unknown in the past. During these procedures, the speed measurement is so accurate that
even the slightest movements of the ship - down to a few cm/s - can be displayed.
For automatic track control, knowledge of the speed relative to the bottom is not sufficient; the drift as a
vector has to be known as well.
It is quite easy to determine the drift mathematically as the difference between the speed relative to the
water and the speed relative to the bottom.

3.2 Physical Principles

3.2.1 Speed Measurements with the Aid of the Doppler Effect

The Doppler effect is the physical phenomenon whereby the signal from a transmitter which is moving
relative to a receiver is detected by this receiver as having a different frequency from that of the trans-
mitter. The same applies when the transmitter is at rest and the receiver is moving. In both cases, it can
be stated that - to a first approximation - the frequency shift is proportional to the relative speed between
the transmitter and the receiver.
How can the Doppler effect be used to measure the speed of a ship? In the simplest case, a narrow
sound-beam is transmitted obliquely forward from the bottom of the ship (see Figure 3-1.)

Fig. 3-1 Measuring the speed of a ship by means of the Doppler effect

The Doppler effect occurs for the first time when the sound emerges into the water. As a result, the sound
waves travelling through the water have a slightly different frequency from that of the transmitter. The
sound is reflected diffusely at the bottom, and some of the energy returns to the ship. When the reflected
sound waves moving back through the water are received at the ship, a second Doppler shift occurs; this
second shift and the first one combine additively. Mathematical treatment of the process leads to the
fundamental Doppler equation 1).

In the evaluation electronics, the frequency difference ∆ fD between the transmitted and received
frequency is measured, and by solving the equation so as to find VX the speed is computed and
displayed.

As can be seen from the equation 2), the accuracy of the speed measurement depends not only on the
accuracy with which ∆ fD is measured by the equipment, but also - more significantly - on the accuracy
with which two quantities are known, namely the transmission angle α and the sound velocity c. Techni-
cally, it is easy to generate the transmitted frequency fS so accurately that it does not enter into accuracy
considerations at all. The transmission angle α is affected by two quantities which are associated with
the use of a Doppler log on a ship. These two quantities are:
- Static angular deviations due to different trim conditions.
- Dynamic angular deviations due to roll and pitch movements
caused by sea waves and by wind.
It has been known for a long time that these effects can be considerably reduced by using two transmitted
sound-beams in the plane in which the speed is to be measured; (see Figure 3-27). From the physical
point of view, this is the principle of differential measurement.

Fig. 3-2 Double beam arrangement, also called Janus configuration

The configuration shown in Figure 3-2 is used in the DOLOG 20 systems. This method has become
known as the JANUS principle.
The advantages of the dual beam configuration can be summarised as follows:
- Almost linear relationship between speed and Doppler shift. At a ship’s speed of 50 knots, a linearity
deviation of only 0.03% occurs when the Janus principle is used.
- Measurement errors due to trim, roll and pitch are less that 0.1% for angles less than 3°. With the
single beam configuration, the error is more than one order of magnitude greater, namely about 5%.
- Vertical motion of the ship does not affect the measurement.

As shown by equation 2), the accuracy of the speed measurement also depends on the accuracy with
which the sound velocity is known. The sound velocity depends on parameters such as the water temper-
ature and salinity. The temperature effects are by far more significant, as a change of 1° C in the water
temperature affects the sound velocity about ten times more than a salinity change of 0.1%. In practice,
speed measurement errors of up to 5% occur in direct proportion to the change in sound velocity.
Various methods are known for the reduction - or even the complete elimination - of this type of error. For
example, one possible solution is to measure the water temperature in the vicinity of the transducer, to
perform a temperature-depending correction in the Electronics Cabinet, and to display the resulting
corrected value.
A more accurate - though more complicated - method is to measure the sound velocity in the vicinity of
the transducer. As in the case of temperature measurement, the measured sound velocity can be used
to derive a factor which can be utilised for automatic correction of the displayed speed.
Both of the above-mentioned methods have already been realized in practice, with additional cost for
measurement and computation. In the ATLAS DOLOG system, a third method is used which permits
automatic correction of the sound velocity effect without any additional measurements, and which has
greatly increased the reliability, accuracy and maximum measurable speed as a result of the design of
the log. This remarkable step forward in Doppler log technology is based on a unique transducer design
which is almost ideally suited to the conditions on ships.

3.2.2 The ATLAS DOLOG Transducer

In hydroacoustic technology, the hydroacoustic transducers serve the purpose of converting energy into
the form required for transfer and processing. When operated as transmission transducers, they are fed
with electrical energy, which they convert into sound waves suitable for propagation in water. In the case
of reception, an acoustic signal arrives at a reception transducer, is converted into electrical energy and
is thus available in a suitable form for processing. Expressed in general terms, transducers act as the
interface with the propagation medium, namely water. The main technical characteristics of transducers
include the beam pattern, the centre frequency, the bandwidth, the efficiency etc.
The beam pattern of a transducer is a geometrical pattern which indicates those directions - relative to
one or more axes of the transducer - in which the sensitivity or the radiated power is maximum. The beam
pattern shows the directivity. The centre frequency is the operating frequency at which the transducer
radiates maximum power into the water, whereas the bandwidth indicates the extent to which the
frequency can be detuned from the centre frequency before the radiated power falls to about 60% of its
maximum value. The beam pattern information generally applies only to frequencies within the bandwidth.
The efficiency indicates the magnitude of the losses which occur in the transducer during the energy
conversion process. It is defined at the ratio of the acoustic energy output to the electrical energy input.
From the streamlining point of view, it is highly desirable that the transducer should be flush with the
bottom of the ship, without any disruptive discontinuities. However, Doppler theory requires that sound
waves should be transmitted and received obliquely at a certain angle relative to the transducer face.
From antenna theory, it is known that Hertzian dipoles which are arranged in groups in a plane, and
which are activated with the same frequency but different phases in accordance with given rules,
generate directional beams with a vector which is not perpendicular to the plane containing the dipoles.
The transmission angle depends on the phase shift between adjacent elements and on the distance
between them. Applied to hydroacoustic technology, this means that a plane transducer array consisting
of several transducer elements can generate directional sound-beams whose direction can be varied.
The configuration of the individual elements of such a transducer is chosen in such a way that the exci-
tation with a four-phase voltage produces a radiated beam at an angle α in accordance with equation 3):

cos α =

elements, measured in the plane containing the longitudinal axis of the transducer
c sound velocity in water

Figure 3-3 shows the geometrical arrangement of the individual elements of this kind of transducer array,
consisting of round elements grouped into staves of four to six elements each.
As already stated, a Doppler frequency shift ∆ fD occurs, depending on the sound velocity c, the horizontal
speed VX of the ship in the direction of its longitudinal axis, (Figure 3-1), the transmission frequency fS and
the transmission angle α, according to equation 2). If equation 3) is now substituted in equation 2), the
following is obtained:

∆ fD VX fS 2 = VX
= = 4)
fS c 4a 2a

Equation 4) reveals the remarkable feature of the transducer design and its phase excitation described
here, namely that the sound velocity c - whose compensation is always critical and expensive in the case
of other transducers - is eliminated from the Doppler-based measurement of the ship’s speed.

The Doppler frequency shift ∆ fD now depends only on the spacing a between the transducer elements
(which is constant for a given transducer) and on the horizontal speed VX. Equation 4) shows in addition
that the Doppler frequency shift is also independent of the transmission frequency. If equation 3) is rear-
ranged as follows:

cos α 1 5)

It can be seen that there is a linear relationship between cos α and the sound velocity c. In the case of
the plane transducer with phase excitation, therefore, sound velocity variations are automatically compen-
sated by the fact that the transmission angle α varies correspondingly with the sound velocity. The
DOLOG system’s evaluation electronics, contained in the Electronics Cabinet GE 6010, fulfils the condi-
tions that are necessary for operation of the transducer array.

3.3 Software Specification

Under the control of the operating system, the DOLOG 20 program runs at several priority levels in
accordance with a hierarchy. The control program for the measurement procedure in the DOLOG meas-
urement cycle has the highest priority; some parts of this program must run without being interruptible by
external interrupts.
The control parameter for the program execution is the depth of the bottom. The software routines
depend on the measured depth; examples of these routines:
- Measurement relative to the bottom only: BT (BOTTOM TRACK)
- Measurement relative to the water and bottom: BT,WT (WATER AND BOTTOM TRACK) in one
measurement cycle
- Measurement relative to the water only: WT (WATER TRACK) if the signal reflected from the bottom
is too week because the water is very deep or there is no bottom signal.
In order to detect the control parameter, namely the bottom depth, with as little interference as possible,
a time window is set up - under program control - over the expected depth value as computed from the
past. This depth window serves the purpose of filtering out the bottom echo from a noisy background,
and of controlling a bottom track gate in accordance with the bottom echo in such a way that only reflec-
tions of the transmitted pulse at the bottom go to the frequency tracker for evaluation.
The measured Doppler information is then available as a 16-bit data word at the integrator output.
The measurement results are generated from the data that are read out of the integrator and evaluated.
After the read-out, data are first subjected to a plausibility check depending on direction, and in the case
of a good measurement the result is released for further evaluation.
If the measurement is bad, a substitute value is formed, and if this is repeated too often a fault bit is set.
Then, in the processor, the JANUS difference is formed from the AHEAD/ASTERN and STARBOARD/
PORT measurements and is subjected to a correction in accordance with the specified values.
The individual measurement values (longitudinal, transverse) are fed to an average procedure for a
constant period of time (1... 2 seconds approx.) in the course of the program, and are then output.
In addition to the direct measurement values, derived data that are needed by the navigator must be
computed and displayed, e.g.:
- Drift angle
- Resultant distance travelled
- Depth of water (only if an approved navigation sounder is connected)
The control signals for the connection of the standard peripherals are generated on the assembly
GE 6010 G 207, Standard Interface. Driving is performed cyclically by the processor with conversion of
the primary data v longitudinal [VL] and v transverse [Vg] into the derived output data that are required.
One typical output is the True Motion TM output, for example, with its pulse rate of 200 pulses/NM. The
pulse rate is obtained from a fixed frequency by means of a programmable divider.
The data for the display units and for the navigation computer are transmitted via a serial interface which
is operated cyclically by the processor in the course of the program.

The Control and Display Unit AZ 6044 is the main display of the DOLOG equipment. It can be
programmed as a MASTER or SLAVE. Possible is only one MASTER in the DOLOG-System. Only the
MASTER delivers 2 signals to the Electronics Cabinet GE 6010:
- an auxiliary DC 24V power signal to switch on the power supply via a relays in the GE 6010 and
- some digital serial data for setting parameters in PROGMODE and for control some functions on line
in the GE 6010.
Each AZ 6044 contains three display lines with 8 positions-each fully ASCII compatible - for displaying
measured and computed values. The control, what shall be indicated, is through the integrated operating
key panel with integrated LED´s for validation of the key functions.
The Control and Display Unit contains functional blocks for driving the LED dot matrix displays and inter-
rogating the control keyboard. For these purposes, data are sent to (only MASTER) and received from
the Electronics Cabinet GE 6010 via a serial interface with built-in processor.
A power supply assembly provides the necessary voltages for the displays and functional blocks. The
individual circuits are protected by fuses against short circuits. A fan provides the required internal circu-
lation of air.
All components are accommodated on two PC boards which are secured in the casing by the means of
headless screws. The functional blocks are connected by means of connectors and ribbon cables.
The casing is made of aluminium, which is anodised and painted. The interior of the casing is protected
against water spray.

This assembly contains the processor for the input/output functions of the displays, for interrogation of
the operating keys, and the power supply assembly for the required voltages. The processor is connected
to the CPU in the Electronics Cabinet and can exchange data via a serial interface. The data of the oper-
ating keys are requested via the connector J1. The data, addresses and control signals for the displays
are routed via J2. An EPROM (32 k x 8) is provided as the program memory. The data memory consists
of a RAM (2K x 8); in the event of power failure, the data are protected by a lithium battery.
The processor receives a data telegram - one per second - from the electronic unit GE 6010 and
computes the data to be displayed every two seconds. Depending on the choice of the operator via key
control four different data sets can be displayed on the three rows of LED dot matrix displays.If more than
one AZ 6044 are connected to the serial interface, they can display different data because of their built
in intelligence.
The assembly also generates the brightness control signals, which are programmed by the processor via
shift registers. A built-in temperature monitor decreases the brightness of the heat-producing displays if
the internal temperature is too high. After a brief power failure, the processor is automatically started by
a reset pulse.
The power supply assembly of the AZ 6044 G 211 receives AC 24V from the transformer. This is
converted to + 5V (5 A) by a switched-mode power supply unit. In addition, + DC 24V (unstabilised) is

subjected to be chromium-plated as surface treatment.
The cable glands of size M24 x 1.5 and M30 x 2 which are fixed to the rear element are made of brass.
Their surfaces are electrically nickel-plated. DIN 84 cheese -head screws of all sizes that are used in the
unit are made of stainless steel.
All functional electronic blocks without the 5V power supply consist of double Eurocard assemblies. They
are accommodated in an assembly holder in the upper part of the hinged frame. Under the assembly
holder, there are two fans which ensure circulation of the air in the closed cooling system. The power
supply assembly with transformer, mains filter, start-up relay and stabilisation electronics is mounted on

3.4.3 The Functions of the Assemblies

3.4.3.1 Transmitted and Received Signals

The transmission signals are generated under processor control. They are converted into acoustic power
by the transducer, and are transmitted directionally by control of the transmission phases. They are
reflected by the water or by the bottom of the sea and return to the transducers, where they are amplified
according to the range and are processed for evaluation of the speed-dependent Doppler shift.
The Doppler shift is measured via a digital closed control loop depending on transmitting direction on the
Frequency Tracker Assembly, GE 6010 G 204. After completion of the measurement, the CPU - under
program control - requests the measurement value in the form of a signed 16-bit digital word, and (after
a successful plausibility-check) computes from all 4 words in accordance with
- fore,
- aft,
- port and
- starboard
the longitudinal and transverse speeds and measurement results derived from these speeds, e.g. the
resultant distance travelled.
For successful Doppler measurement, it is important to evaluate only those signals that are reflected from
particular depths, for example in the case of speed measurement relative to the bottom.
For this purpose, the Timing Assembly, GE 6010 G 203, provides with correct depth-dependent time
windows, that the Doppler shift is only computed out of echoes, that are for example in bottom mode only
reflected from the bottom. The correct timings for all windows are computed from the filtered foregoing
echoes; it is also done in the CPU under program control.
For to output the computed speed values, serves the Standard Interface Assembly GE 6010 G 207. It is
build up with circuits for of the periphery dependent speed - and distance - outputs and for that purpose
the assembly contains the following for example:
- 9... 20 mA current outputs, e.g. corresponding to a speed of -5... +30 kt
- True motion outputs (sign and clock), e.g. 200 contact-closings per NM
- Analogue inputs, e.g. for rate-of turn gyro signals for computing the second transverse speed.

The transmitter has the task of generating high-frequency energy at the desired transmission frequency
and of feeding this energy to the hydro-acoustic transducers by means of a cable. The energy is trans-
mitted obliquely by the phase-steered transducer and is reflected diffusely at the bottom or from the water
volume. A portion of this reflected energy is received by the transducer with directional selectivity.
In order to implement the Janus principle, it is necessary to switch over the transmission direction (and,
similarly, the reception direction) from ahead to astern and from starboard to port and vice versa. This is
done by using the four-phase transducers SW 6049 and by switching over the phases of the electrical
signals being fed to it.
In addition, the assembly contains a low-noise preamplifier for each channel. This amplifier raises the
level of the received signals by about 16 dB.
For DOLOG 22, 23 there is the need for 4 channels. For that purpose are two identical assemblies
GE 6010 G 201 installed in the electronics unit - each assembly with two channels.

3.4.3.3 Reception Function; Receiver Assembly GE 6010 G 202

The reception function is divided into the following subfunctions:

- Mixer controlled by switches for changing the direction of reception by different phases
- Compensation for the range-dependent attenuation, 20 lg (2 r) for spherical losses and a (r)
for absorption losses
- Identification and detection of the bottom echo
- Elimination and detection of reverberation and noise echoes with respect to the bottom echo
- Control of a bandwidth-optimized filter so that it corresponds to the shifted Doppler spectrum
- Clipping of the Doppler signal
- Switching the Doppler signal through for frequency analysis on the basis of the criterion adequate
amplitude.
The signals (two phases per Transmitter Assembly) go to a processor-controlled, direction-dependent
mixer stage in which the four directions AHEAD, ASTERN, STARBOARD and PORT are selected by
phase switch-over. After that, the signal is amplified in the IF band by a TVC amplifier, is filtered, and is
fed to a clipper amplifier for evaluation of the Doppler frequency. The bottom channel serves the purpose
of identifying the amplitude of the bottom echo.
For small surveying vessels in shallow water operation there is a special version of the receiver board:
Receiver Assembly GE 6010 G 223. It differs from the G 202 mainly in the following functions:
- reduced TVC: running time only to about 50m,
- reduced gain for the bottom channel and
- only usable for - aft - direction: DOLOG 21.

3.4.3.4 Timing-Control; Timing Assembly GE 6010 G 203

In the DOLOG, the Timing Assembly coordinates the interaction of the transmitter and receiver, and
controls the processing of the measurement data.
The pulse length of the transmitter is controlled in such a way that, depending on the echo travelling time,
sufficient time remains after the transmitted pulse to allow measurement of the reverberation in the water
before the bottom echo masks the sound from the water. After arrival of the bottom echo, the Timing
Assembly enables a time window within which satisfactory Doppler measurement relative to the bottom
is assured.
In addition, the Timing Assembly contains a processor-controlled bottom echo logic circuit which recog-
nises as bottom echoes only those echoes that have a particular level relative to a reference level.
This reference level is computed from the sliding mean of the last 8... 10 (approx.) bottom echoes that
were identified. As an additional criterion, there is a time window which covers the time during which the
bottom echo is expected; this time too is derived from the past.
When a detected and verified bottom echo has passed the interrupt logic, it generates an interrupt to the
CPU. This interrupt starts a flying interrogation of the depth counter for the bottom echo. The number of
cycles stored at that moment in the counter is a direct measure of echo traveltime between the beginning
of the transmitting pulse and the detected bottom echo. The counter is set to zero program controlled
before the start of each sounding cycle.

3.4.3.5 Frequency Analysis; Frequency Tracker Assembly GE 6010 G 204

If the transmitted beam of the Doppler log is tilted by phase steering from ahead to astern, while at the
same time the reception direction is switched over too, the reception frequency in the ahead beam will
of course be different from the astern beam by an amount which depends on the ship’s speed in the
direction of the beam’s tilting plane.
The frequency measuring circuit is build up as a digital closed control loop. That means, that there are
no drift effects as they are normally combined with analogue circuits. The frequency generation is crystal-
controlled.
The task of the Frequency Tracker is to determine the main frequency of the spectrum in each direction,
to control a narrow-band filter in such a way that the main frequency of the spectrum is the same as the
centre frequency of the filter, and to store the detected centre frequency in the pauses between the
echoes. In the case of short transmission pulses, when the transmission spectrum is broader than the
Doppler spectrum, the Tracker must be able to correlate from pulse to pulse.
At the input of the Frequency Discriminator is a control gate. Through the Gate - input the tracker is
controlled in such a way, that only echoes with an adequate amplitude can pass the gate.
After a successful measurement, the Doppler frequency is available as a 16-bit word with sign at the inte-
grator output.
In addition, the assembly contains the programmable central clock. By means of control words, the trans-
mission frequency and the mixer frequency can be programmed, as well as the phase position of the
transmission driver signals for the change of direction. In the case of reception, the desired reception
direction can be selected by phase switch-over by means of a control word.

3.4.3.7 Processor Function; Central CPU Assembly GE 6010 G 211 (AZ 3023 G 201)

An INTEL D 8088 microprocessor was selected as the CPU for this assembly. This microprocessor
behaves as a 16-bit processor internally and for the software user, but from the hardware point of view
it only handles 8-bit data exchange.
The processor works at a clock rate of 5 MHz, which is obtained in the oscillator component D 8284 from
a 15 MHz quartz crystal, with a duty cycle ration of 2:1. The address signals, data signals and control
signals which are necessary for communication with the memories and peripherals are demultiplexed,
decoupled and power-amplified in a buffer chain. For external accesses to memories and peripherals of
the assembly (e.g. DMA), this buffer chain can be put into the high-impedance state by means of the BUS
REQUEST signal. Enabling of the bus is confirmed by a BUS ACKNOWLEDGE signal.
The address area of this interface is 20 bits (= 1 MByte address area) for memory accesses, and 16 bits
(= 64 Kbyte) for peripheral accesses (I/O).
The program memory of the card consists of six PROM plug-in locations which permit the use of
EPROM’s of types 2732, 2764, 27128 and 27256, as well as static RAM’s with 8 k x 8 organisation,
depending on coding by means of plug-in jumpers.
Use of the 27128 gives a PROM memory area of 96 Kbyte, and use of the 27256 gives a PROM memory
area of 192 Kbyte.
The data memory covers 64 Kbyte of dynamic RAM, which is matched to the CPU timing by means of a
RAM controller D 8203. Data exchange with the CPU takes place by the handshake method via the wait
state generator.
The peripherals of the card consist of:
- Five serial line current interfaces, potential-isolated
- Three 16-bit timer channels: two channels are clocked via an internal clock-source (312.5 kHz), and
one channel is available for external clock pulses up to 1 MHz (signal TINT 16). The internally
clocked timer-outputs trigger interrupts.
- Eight interrupt levels; the priority of the interrupts is defined by a programming platform. The inter-
rupts are allocated as follows:
- Two timer-outputs
- Two serial interfaces (transmitter buffer empty and data available)
- Four external sources
The external interrupt INT 2 can also be fed to the third timer-channel by inserting R 1.
- Visual output of status information via a 16-bit LED chain
- Parameter input or selection of software modes via an 8-bit DIL switch.

3.4.3.8 Power Supply Assembly GE 6010 222

See (Figure 3-15), Block circuit diagram of the Power Supply Assembly, GE 6010 G 222.
This assembly generates the voltages needed for operation of the Doppler log’s electronics. These volt-
ages are as follows:
- + 100 V / 0.2 A. Stabilized voltage for generation of the electrical transmission energy. This circuit
charges buffer electolytic capacitors which act as reservoirs for the transmission energy and which
are discharged during the relatively short transmission pulse. When the operator switches off the
electrical supply, the transmission capacitors are discharged in about 10 seconds via a relay and a
power resistor.
- + 15 V / 0.5 A and - 15 V / 0.5 A. Stabilized voltages which mainly serve to supply the analogue part
of the Doppler electronics and which are therefore well filtered.
- + 5 V 1.5 A. Spare voltage for extensions.
- + 25 V / 3 A. Unstabilized voltage. From this voltage, an external switched-mode power supply unit
generates the 5 V/12 A voltage that is needed for the digital electronics of the DOLOG.
- + 24 V, - 24 V. Unstabilised auxiliary voltages.
For each current path, there is a pilot lamp which indicates the presence of voltage on the current path.
In addition, all current paths (except the 25 V/3 A path) are checked for voltage by a detector circuit. If
deviations of about 50% or more occur, the output signal power fail is set and can be requested under
processor control.
In the line of the high voltage path a glow - discharge lamp acts as indicator for the transmitter power
supply. It indicates a voltage of more than 50 to 70 volts.

3.4.3.9 Basic Wiring Board, GE 6010 G 219

The wiring on the rear-mounted Basic Wiring Board, GE 6010 G 219, serves to interconnect the assem-
blies. This board holds the 32-, 64-, and 96-contact sockets for the plug-in assemblies of double Eurocard
format. The printed conductors for connection of the sockets are produced by an etching process, and
the sockets are soldered permanently in their positions. Connecting wires can be added later for special
versions.
A connector is provided for connection of the Power Supply Assembly GE 6010 G 222, and another two
connectors for connection of the standard peripherals via the Interconnection Board.

3.4.4 Distribution Box

3.4.4.1 Structure and Function

The unit Distribution Box GE 3036 performs two main functions in conjunction with the DOLOG 20
system:
- Provision of the RS 422 interfaces in accordance with standards, for the connection of
- 2 digital Wing Displays, separate drivers;
- 2 additional external units or systems; separate drivers, galvanically isolated; and
- 1 Current Loop 20 mA interface; as an option, this can be switched over to RS 422 or RS 232 by
means of an Interface Assembly which can be plugged in;
and
- one interface circuit for START-STOP signals from the navigation echosounder ECHOGRAPH
ATLAS 9205 to the DOLOG instead of the previous echosounder ATLAS 481.
The unit consists of an RF-tight casing, an assembly mounted in that casing and containing a DC/DC
converter, the necessary receiving and driving circuits, and the terminals for connection of screened
ship’s cables.
The unit can be connected directly to the Electronics Unit GE 6010 of the DOLOG 20 via a 3 m long
cable which is also supplied and is already connected in the GE 3036. For this purpose, the cable already
has the necessary connectors attached to it.
The power supply for the Distribution Box comes from the Electronics Unit GE 6010 via the above-
mentioned cable, and consists of 24 VDC unstabilised.
On the input side, the serial data telegrams as per NMEA 183 are fed into the unit from the GE 6010 via
a Current Loop 20 mA interface.
The START-STOP signals from the echosounder ECHOGRAPH ATLAS 9205 are received and are
formed into pulses having a particular length; then, with positive logic, they are fed via drivers onto the
cable leading to the GE 6010.

3.4.4.2 Assembly DOLOG INTERFACE, GE 3036 G 200

This assembly contains all components, including a power supply unit with a 24 VDC voltage input. The
voltage goes directly from the Electronics Unit GE 6010 via the cable to the DC/DC converter, which
generates the stabilised voltages.
The cable and GE 3036 are protected by the fine-wire fuse F1, which is accessible after the cover has
been unscrewed. The light-emitting diode CR5-green – indicates that the supply voltage is present and
that the 12 V voltage regulator is running.
The serial interface signals STX+, STX– go via an optocoupler CNY 17– IC804 – to
- the inputs of four RS 422 drivers and
- a 20 mA current driver.
Two RS 422 drivers, IC 501 and IC 301, provide galvanically isolated RS 422 interface signals, each
having its own ground. Their polarity can be set via a jumper at TP2: inverted or not inverted.
Two RS 422 drivers, IC 801 and IC 901, with the chassis of the unit acting as the reference ground. The
polarity for both drivers can be set via a jumper at TP1: inverted or not inverted. These interfaces must
be used for DOLOG-internal units, e.g. the digital displays known as Wing Displays.
20 mA Current Loop interface: Since the GE 6010-internal interface STX+, STX– is occupied by the
task of connecting the Distribution Box, the 20 mA Current Loop interface (output interface) is
available as a spare interface, especially in the case of retrofitting. Via the connector J1 – normally
not used – a plug-in slot is available for Interface Driver Boards. The following Driver Boards can be
plugged in:
- TTL: SH 3014 G 201 *)
- RS 232: SH 3014 G 204 *)
- RS 422: SH 3014 G 203 (with galvanic isolation, switchable)
*) Permissible only for short cables and for testing. For activation of these interfaces, S1 must be
switched over to position 2.
Signal former circuit for start-stop pulses: The START-STOP interface of the echosounder ECHO-
GRAPH ATLAS 9205 cannot be connected directly to the Electronics Unit, but only via pulse former
circuits, namely one for START and one for STOP. Each signal goes from the echosounder to an opto-
coupler CNY 17 for galvanic isolation. In the monoflops MF which follow, the pulse length is limited to 50
µs, the same as with the 481 echosounder. The reference edge is the positive edge. Via the output
circuit, whose specification likewise corresponds to that of the 481 echosounder, both signals are
passed on via the connection cable to the GE 6010.

3.4.4.6 START-STOP Input Interface

Description
This interface is used only for connection of the navigation echosounder ATLAS ECHOGRAPH 9205. In
the GE 3036, it acts as a pulse former for the Electronics Unit GE 6010.
There, the time is measured between the beginning of the START pulse, which occurs in synchronism
with the transmission pulse, and the beginning of the STOP pulse, which occurs in synchronism with the
bottom echo.
In the case of a two-channel ECHOGRAPH 9205, it is always only channel 1 that is output:
- Channel 1 display: START–STOP signal 1
- Channels 1 + 2 display: START–STOP signal 1
- Channel 2 display: START only
- Single-channel ECHOGRAPH 9205:In all cases, channel 1 only
The depth that is output is always DBK (Depth Below Keel). Reference sound velocity: 1500 m/s.
For the DOLOG, the START pulses mean that a 9205 is connected and is in the switched-on state. If the
START is not followed by a bottom pulse, or if acoustic disturbances are present and suppress the
bottom echo, the display AZ 6044 shows a dashed line (mode SAIL 2 is set) in the line for the depth
display.
If there is no 9205 connected, or if the echosounder is in the switched-off state, the corresponding line is
blanked in the case of SAIL 2.

3.5.1 Digital Display Unit AZ 1017 (Not for new deliveries since 1998)

In the DOLOG 20 systems, the Digital Display Unit is used as a slave display unit, e.g. on the bridge
wings.
The three display lines are connected in parallel with the Control/Display Unit and provide the following
informations:
- speed transverse FWD
- speed longitudinal
- speed transverse AFT (only DOLOG 23)
The Digital Display Unit AZ 1017 contains the following assemblies:
- Power Supply Assembly AZ 1017 G 006
- Line Receiver AZ 1017 G 256
- Oscillator and Switch Board AZ 1017 G 238
- Speed Display Assembly AZ 1017 G 257
- Wiring Board AZ 1017 G 297
- Connection Board AZ 1017 G 004
The assemblies are installed in a dust-proof, seawater-proof, closed aluminium casing. The PC board
holder can be pulled out after a screw has been released, thus giving access to the Power Supply
Assembly (with fuses) installed in the casing.
The Digital Display Unit can be mounted at any point on the bridge or in the bridge wings by means of a
fork-type bracket. Alternatively, the unit can be installed in a console or cabinet. The brightness of the
display is automatically adapted to that of the environment by means of a photo-diode.

3.5.2 Universal Digital Display

3.5.2.1 Digital Display Unit UDR

The Digital Display Unit UDR - UDR - is an universal digital slave display unit in the DOLOG system
with a serial input interface, capable of identifying and displaying NMEA sentences of the DOLOG inter-
face.
According to the configuration level of the DOLOG 20 system, the following speeds are measured,
depending on the mode, and output on the serial interface:
- VL: longitudinal speed parallel to the ship’s centreline: DOLOG 21 (longitudinal)
- VqV: transverse speed fwd at transducer location:
VL + VqV : DOLOG 22 (transverse fwd, longitudinal)
- VqA: transverse speed aft measured with the help of the rotational speed of a ROT measuring instru-
ment, VL + VqV + VqA: DOLOG 23 (in addition: transverse aft)
The UDR has a double-line display which is set up in the form of light-emitting diode matrices, thus gener-
ally permitting displays also in a semigraphic form. Thus, characters from the entire ASCII character set
and, in addition, several special characters can be displayed on both display lines. See Figure 3-22:

Normally, the measured value is displayed on the lower line, such as the speed with dimension kt, while
status and identification of the measured values etc. are shown on the upper line, For the speed, for
example, these are the direction and the references BT or WT.
In the DOLOG 20 system, the UDR is exclusively used for speed display; in this case, the display of VL,
VqV or VqA can be programmed as required. The display unit can be adjusted to the requirements
prevailing during navigation by a suitable parameter specification in the set-up menu.

Some keywords:

NAVIGATION display:
- VL or VqV displays at transducer location or VqA aft, adjustable during installation
- Signs programmable depending on installation via set-up menu, according to direction of view
- Priority of BT or WT selectable; automatic switching BT to WT or reverse
- Integration time/display always 2 sec
- 1 digit position after point, rounded off (1/10 kt)
- Averaging, floating via 2 successive measured values (= 2 sec integration time)
- Dimension: kt; no switching to m/s provided.

In the automatic mode, the measured value to be displayed is automatically selected by the UDR
according to the specified BT or WT: for example, if BT has been selected with priority, the speeds
against bottom are displayed as long and as far as available. If such a measured value is not available,
e.g. at excessive water depth, the unit automatically switches to the reference WT with the corresponding
speed values and displays them. For WT with priority, the procedure applies analogous to BT. Normally,
display of the speed against ground - reference BT - is selected during navigation.
Connections for an external dimmer are provided: the brightness can be increased or decreased via 2
pushbuttons - make contacts.
The display unit is provided for console installation and as a case version with bracket mounting. Figure

4.3 Switching on the Battery for the Data Memory

The units of the equipment are delivered complete with a built-in battery for the data memory. This
primary battery can be switched off to prevent it from running down during storage or prolonged non-use
of the equipment. Interruption of the electrical supply after the equipment has been started causes a loss
of the stored variable operational data, e.g. the distance counter reading.

4.5 Calibration

4.5.1 General Information

Before the equipment begins regular use, it must be calibrated with the aid of a known, measured
distance.
The measured distance must be a mile or more. The equipment must be set-to-work completely before-
hand. There must be definite speed displays without any disruptions. The speed values must come form
the BOTTOM TRACK mode ("B").
The measured distance must be travelled at least once in each direction.The distance values displayed
after the trips along the measured distance must be compared to the measured distance. Any differences
should be converted to percentages, and these should be input to the equipment as correction values by
means of "PROGMODE" (see Section 4). It is not necessary to take account of any transverse distances
travelled in this short measured distance, as they lie within the overall tolerance.

- Press the key SAIL 1. During the calibration process, the longitudinal distance value is displayed on
the middle line. (Values on the top and bottom display lines are of no importance).
- Press the key RESET. The distance counter stops.
- When sailing past the starting point of the measured distance, press the key RESET again. The
distance counter goes back to zero and starts counting.
- When sailing past the finishing point of the measured distance, press the key RESET. The distance
counter stops.
- Read the distance travelled (displayed in kilometers) and compare the reading with the longitudinal
value of the measured distance. (Perform a second measurement trip).
- If the values are not equal, calculate the difference as a percentage.
Example: Displayed value = 0.990 km
Measured distance = 1.000 km
= 0.010 km
The displayed value is 1% too low. The distance processor must be corrected by +1%.
- Switch the equipment to "PROGMODE" (see Section 4.6) and input the longitudinal correction factor
as a percentage (see Section 4).

4.5.3 Setting-to-Work Record of Parameters

If the MEMORY Assembly GE 6010 G 208 fails, the system parameters stored in the EEPROM are lost
and cannot be recovered.
For this reason, the parameters determined or defined during setting-to-work must be recorded in writing
by the engineer who performs the setting-to-work.
After the form has been filled in, it must be attached inside the Service Manual.

4.7.1 General Information

In the following, there are notes and setting data for individual assemblies, indicating the procedure to be
used for the repair or replacement of assemblies or when trouble-shooting. The assemblies are dealt with
in order of their item numbers. A test sequence is stated only where this is necessary. Failures of assem-
blies can be detected by means of the test system (SELF CHECK - see Section of the Operation Instruc-
tions).
The positions of the adjustment points and setting points can be found in the component position
diagrams of the PC board assemblies if they are not shown in the sketches.
The locations of the most important assemblies are indicated in the following drawings.
To some extent, MOS assemblies are used in the equipment. They are identifiable by means of orange-
red printing on the front panel and/or on the assembly (PC board).
If touched, MOS assemblies might be destroyed by electrostatic fields.
When exchanging and transporting MOS assemblies, it is essential to obey the rules stated in the
Section.

4.7.2 Locations of Assemblies

The individual assemblies are plugged or screwed into the casing or the assembly holder. The methods
of opening the units are described in Section 5, "The Exchanging of Parts".

4.7.4 Function of the Digital Display Unit AZ 1017

4.7.4.1 Functions on the Speed Display Assembly AZ 1017 G 257

Control of the Display Brightness

The digit brightness of all displays is controlled by the photoresistor R16 in conjunction with IC15/10 and
IC18/10. The brightness is controlled by varying the duty cycle ratio.
The switch-on time Ton = 0.06 ms is formed by means of R17, R18 and C6. The switched-off time Toff
= 0.74 ms is set by means of R15 in conjunction with R14, R43 and C6, with the photoresistor darkened.
For the display of direction and units, Ton is prolonged by Tpr = 0.06 ms (IC25). Tpr is set by means of
R47. With Ton plus Tpr, the switched-on time increased, thus compensating the difference in brightness
between the digit displays and all other displays.

UTP1 L
TON
TOFF

UTP12 L
TV TOFF

Fig. 4-38 Oscillograms at the test points TP1 and TP12

If the brightness of the environment increases, Toff becomes smaller. As a result, the switched-on time -
and hence the display brightness too - increases.
The output signal at J1 (pin C1) controls the digit displays on G258; it goes via J1 (pin C3) to IC’s 1,2,3
and 4. The output signal at J1 (pin A6) controls the display of units and directions on G258 via J1 (pin
A4).

Lamp Control
The switch-over signal for the mode display BOTTOM TRACK (BT) or WATER TRACK (WT) comes
from G256 and goes on to G257 J1 (pin C25). The WT display is activated via IC5, Q6, whereas the BT
display is switched on via IC23/2, IC5, Q5.
The switch-over signal for the unit of speed measurement is controlled by G238 and is present at J1 (pin
20). It causes illumination of the displays via IC23/10, IC5/Q3 for „kt“ and via IC5, Q4 for „m/s“.
At the most significant figure (V4) of the display, the digit "0" is suppressed (darkened). This is done by
IC16 and IC12/13 at the end of a counting period.

Counting Direction Code

The ahead or starboard distance pulses go via J1 (pin C5) and the astern or port distance pulses go via
J1-C6 to the gates IC17/3 and IC17/4, which have been switched over to the R-S flip-flop. The flip-flop
changes the counting direction of the counters IC8-IC11 via IC7/10.
The counting direction is also changed when the four-stage decade counter reaches the digit combination
00.00 (IC11, IC18/2, IC18/4, IC17/10, IC12/1, IC7/10). The direction pulse is taken over by IC13/1 at the
end of a counting period at IC12/1, and illuminates the corresponding direction display via IC5, Q1, Q2.
Depending on the coding of the pins J1-A17/C17 and J1-A18/C18 (longitudinal or transverse speed), two
display-lamps are connected in parallel so that they indicate a direction.

Counter and Memory Control

The square-wave time base pulse goes into the circuit via J1 (pin C13). Its positive edge generates a
positive pulse (C10, R34) at IC7/2. If a negative distance-pulse is present at the same time at the counters
IC8-IC11, this pulse is blocked by IC6/6, IC13/13, IC14/11 and R35, C11 at IC14/4. No loading or preset-
ting pulse can reach the memories IC1-IC4 or the counters IC8-IC11 during a counting process. If the
distance pulse becomes positive, IC14/4 lets the pulse through, and its negative edge generates a posi-
tive pulse via IC6/2. This pulse becomes negative again because of C5, R10, IC14/3, with a pulse length
of 1.8µs, and is present as a loading pulse at the memories.
C4, R9, IC6/4 and IC14/10 turn the negative loading pulse into a positive presetting pulse of length 18ms.
Input J1 (pin C15) is for test purposes.

The input signals (120 pulses/m) go via pins J1-A5, C5...J1-A10, C10 to the differential input stages IC1,
IC2. Via the interference protection circuit IC13-15, IC18, they reach the variable dividers IC3-8. These
dividers are required for the switch-over of the integration time for obtaining the speed. The dividers are
set by means of the switches S1-S4 on the PC board G238. The input pulses are divided down by the
dividers.
For the transverse speed at the bow, the divided-down pulses are present at the pins J1-C1, C2. For the
longitudinal speed, they are present at the pins J1-C3, C4. For the transverse speed at the stern, they
go via IC12 to the pins J1-C11, C12.
The switch-over signal BOTTOM TRACK or WATER TRACK is taken via the input stage IC2/14 to J1
(pin 25). The signal DOPPLER OK is taken via the input stage IC2/3 to J1-C24.

Via the pins J1-A23-25, C32, the switch S5 on G238 sets the pulse dividers IC9, IC10 on G256. By
means of the switches S1-S4 and IC1, the dividers IC3-IC8 on G256 are set in accordance with the
selected speed measurement integration time, units of measurement ("kt" or "m/s"), and "DOCKING" or
"SAILING" mode. At the same time, the time base is switched over with the switches via IC6-IC8. The
time base of f = 0.61733 Hz for "kt" or f = 0.6 Hz for "m/s" is then available at pin J1-C13.
A flashing frequency of about 2 Hz is present at J1 (pin C23). It is used for the message signal DOPPLER
OK. This causes 2 Hz flashing of the direction sign, decimal point, unit-of-measurement display and
BOTTOM TRACK (Bt) or WATER TRACK (WT) display. In the event of undervoltage, the circuit Q3-IC10
switches off the display drivers and the display if the supply voltage falls to about 4 V (J1 A29, B29, C29).
The circuit then applies "L" to J1 (pin A2).
The SAILING/DOCKING switch-over signal goes into the circuit via J1 (pin C19). The switch-over signal
for the speed unit displays on G217 and G227 is present at J1 (pin C20).

The electrical supply to the C-MOS logic (except the display drivers) is filtered via L1 and C2. If the
current consumption is too high, the displays are switched off.

4.7.5 Set UP Procedure for Universal Digital Displays

When the system is delivered, it is necessary to program the single unit "Digital Display Unit UDR",
whereas the triple display unit "Digital Wing Display UDR" has already been programmed prior to delivery
and does not have to be reprogrammed except in the case of repairs.

Single Digital Display Unit UDR:

- Programming usually in NAV Mode with fixed point, 1/10 kt, automatic switch-over between BT and
WT with reference BT having priority and with display of longitudinal speed.

Digital Wing Display UDR:

- Programming of longitudinal speed and transverse speeds at bow and stern in Docking Mode,

4.7.6 Setting-to-Work / Configuration / Testing of DOLOG 20 Docking Display

Programming
Note! Reprogramming is not necessary for normal installation or opera-
tion, but only for using the internal test routines or for setting-up non-
standard versions!

The programming mode is entered after completed self-test (with an un-programmed instrument) or if both
"DIM" keys are pressed during power-up. The version number is displayed for about 1 second and the
"DIM" keys are then used to increment/decrement the version number in the range 000 - 255. When a
chosen number is displayed, the programming is verified by pressing key #2.
The following modes are implemented:
Mode no Version
00 Unprogrammed, Factory self test
01-10 Reserved, do not use
11 SD2-11 OEM Docking Log version.
12-14 Reserved, do not use
100 - 114 Demo versions of above indicators, giving pre-programmed data and ignoring all inputs._

Testing
If the instrument is powered without being programmed (or programmed to version #0), a test sequence
is performed.
1 All segments and LED’s are tested with a "running light"
2 All keys can be tested by pressing them, one at a time. The corresponding key number is simulta-
neously indicated on the upper display. On the same time the four outputs can be tested, when key
#1 is pressed, a high voltage is transmitted on output #1. The same applies for outputs #2 - 4.

Output # Terminal #
1 5
2 6
3 7
4 8

When key #5 is pressed, the NMEA output and input are tested with a serial data test sequence that
is transmitted from the NMEA output and expected to be received on the NMEA input. If the input
and output are inter-connected and OK, the mid display will show a "g", otherwise a "b".
3 When key #6 is pressed, this is indicated and the instrument then starts to count seconds for one
minute to check internal timing. This counting can be interrupted by pressing key #5.

The instrument then enters programming ( = 000 ) mode.

4.7.7 Testification of the Electro-acoustic Function of the Transducer SW 6049

The following measurements on the transducer SW 6049 are used to verify the electro-acoustic function:

Measurement 1
1 Switch off the DOLOG Electronics Cabinet GE 6010
2 Terminate the transducer cable SW 6049 G 009 on the Distribution Box SW 6049 G 050 (see Figure
4-42) with four dummy load resistors (100 Ohm each) and four series resistors (1 Ohm each) (see
Figure 4-43)
3 IP switch S1-6 to „CLOSE“. This activates the HF test.
(The HF test generates a transmission signal with a constant amplitude (200Vpp). The pulse length
is about 20ms and the internally simulated bottom echo follows the transmission pulse after about
130ms, corresponding to a bottom depth of 100 metres. In the DOLOG the simulated bottom echo
normally generates a speed of 10kt ahead and 1kt transversely (to starboard).
4 Switch on the DODLO Electronics Cabinet
5 With a dual channel oszilloscope measure all fiur phases (P1, P2, P3, P4) one after the other.

*U1: Voltage drop across the load resistors (100Ohm).

(expected value: 200Vpp)

*U2: Voltage drop across the series resistors (1Ohm).

(expected value 2Vpp)

*Important! The voltages U1 and U2 must be equal in phase!

(For this purpose, set the time base ot the oszilloscope to about 1µs/div)
6 In the table below, enzter the measurement results obtained in 5.

Measurement 2
1 Same as Measurement 1
2 Terminate the transducer cable SW 6049 G 009 with four series resistors of 1Ohm each, as shown
in 4-43

A1 NMEA 0183 Interface

A1.1 Preface

This interface specification is applicable to interconnection and to serial data communication between the
ATLAS DOLOG 20 and devices or systems with NMEA Ports.That may be within the DOLOG 20 system
itself or with external systems.
The ATLAS DOLOG 20 is a Sonar Doppler Log System, that measures speed and distance against
bottom or / and water volume.
The protocol specification complies with NMEA 0183-Standard Version 1.1 + 2.0, 2.1) for interfacing
Marine Electronic Navigational Devices. For more comprehensive information, consult NMEA NEWS
JAN/FEB 84 and preceding issues and the NMEA version 2.1, October 15, 1995.
The electrical signal characteristics complies with ATLAS-standard, which is based on 20 mA current
loop definition.
Optional RS 422 interfaces are available with the Distribution Box GE 3036 O 000.
For further information see chapter: Distribution Box (DOLOG 20 Service Manual).
A1.2 Hardware Specification

A1.2.1 20 mA Current Loop

A1.2.1.1 Interconnection

The interface enables unidirectional data transfer between the DOLOG 20 and the external system or the
Distribution Box GE 3036 if connected.
The interconnection between units is by means of two conductor shielded wires. The two conductors are
referred to as the signal line and the return line. The overall shield should be connected to chassis only
at one end.
The transmitting device is active, the receiving device is passive and deductible optically.
Cable length : tax 100m
Cable type : ship cable, FMGCG or similar

If the Distribution Box is part of the DOLOG System, its input is connected to E 96, E 97 of the GE 6010
G 220. In such case the current loop output is available in the GE 3036.
A1.2.1.2 Electrical Signal Characteristics

The signal state is defined by the current on the signal lines:

- loop current 20 mA: logical ’1’
(idle, marking or stop bit state)
- loop current 0 mA: logical ’0’
(active, spacing or start bit state)
The loop current of 20 mA in the idle state is for detecting a broken line. Multiple talkers or multiple
listeners not possible.
A1.2.2 RS 422 output

There are two RS 422 data outputs for external systems within the Distribution Box GE 3036 for unidirec-
tional data transfer between GE 3036 (DOLOG 20 -equipment) and external systems.
Each of the RS 422-drivers has an isolated output with an additional isolated ground.
The two conductors are referred to as the signal lines “A“ and “B“, twisted pair. In addition it is recom-
mended, to have a third conductor for isolated ground. the overall shield of the shipscable should be
connected to chassis only at an end: Only at the GE 3036.
The transmitting device is active, and the receiving part is passive and decoupled optically.
Cable length : max 100m
Cable type : ship cable, FMCG 2 * 2 * 0,5 mm 2 or similar

Electrical Signal Characteristics

The RS 422 drivers are differential type. The signal state is defined by the voltage between the 2 lines
“A“ and „B“:
- negative voltage on line “A“ with respect to line “B“:
logical “1“ (idle, marking or stop bit state)
- positive voltage on line “A“ with respect to line “B“:
logical “0“ (idle, spacing or stop bit state)
To provide a logic inversion, if necessary, there is a testpoint with two possible bridges on the PC-Board

TP2 - 1 2 3 TP2 - 1 2 3

a. inverted b. not inverted

The receive circuit shall be designed for operation with a minimum differential input voltage of 2.0 Volts
and shall not take more them 2.0 mA from the line at that voltage.
The maximum applied voltage between signal lines “A“ and “B“ and between either line and Ground shall
be in accordance with EIA-422 specification.

- Stop bits 1
Signal timing is compatible with standard asynchronous devices (UART’s, MUART’s) when operating at
the specified Baud rate.
All binary transmissions shall be interpreted as 8 bit ASCII characters (d7 = 0) with parity disabled.
A1.4 Protocol Specifications

The NMEA Standards Committee has defined formatting and syntax techniques to be utilised and applied
for the interconnection and data communication between marine navigation instrumentation. These are
listed and described as NMEA 0183 Standard.
This specification will demonstrate the required parameters for communication between the DOLOG 20
and the external system.
The following messages will be transmitted via the NMEA 0183-Port from the DOLOG 20 to external
system:
- Absolute speed (X- and Y-Axis) = Ground Speed 1)
- Relative speed (X- and Y-Axis) = Water Speed 1)
- Auxiliary Doppler Data 1):
- Depth
- Rate of turn
- Propeller shaft rotation
- Ground and Water Speed based on NMEA version 2.0
- Transverse Ground and Water Speed at ship’s stern.
- Distance Travelled through the Water.
