5. VOLTAGE SELECTION
The output voltage for the phase and reference channels may be selected by two methods:
1. By the connection of the wires to terminal block P12 and position of a wire link in terminal
block P21.
2. By selecting the maximum output voltage amplitude in the device’s menu.
The user should setup the output voltage by method #1 at first, so that the voltage is equal or little
greater than required. Then, the user should adjust the output voltage to the required level by selecting
the applicable settings in the device’s menu (method #2).
Example: It is necessary to power the synchro type repeater with excitation voltage 100 V and
maximum synchronizing voltage 50 V.
1. Select the wiring diagram P12 and P21 from Table 1. For the repeater excitation voltage (equal
to 100 V) select the limit of 110 V. For the repeater maximum synchronizing voltage (equal to
50 V) select the limit of 75 V. Thus, the switching scheme will correspond to the sixth row of
Table 1.
2. For the excitation voltage calculate how many percent makes the target voltage from the
maximum value
and set the value of 90 % using menu. Similarly, calculate the repeater maximum synchronizing
voltage
and set the value of 65 % using menu.
Calculation formula:

6. PRINCIPLE OF CONVERTER OPERATION
6.1 Standby Mode of the Converter
Right after power-up the converter DAC-109 switches to the standby mode. Two course values are
displayed at the display in this mode:
1. Accepted value of course from the NMEA source (e.g. digital gyrocompass)
2. Current value of course at the receivers of analogue signal (for example, at the repeaters
connected to DAC-109).
In this mode, the internal display of the converter looks as follows:
The necessity to display two values of course is caused by the inertia of synchro receivers (see
par.6.5).
In the standby mode the user may enter into the configuration menu of the converter – in order to do
it, it is necessary to press the key [F3].
Attention! After switching on the converter it is obligatory to enter initial positions of connected
analogue repeaters (see par. 6.4).

switched over to the reserve channel when data at the main channel is missing.
Available values of this parameter are: 2, 3, 4, 5, 6, 7, 8, 9, 10 sec.
6.3 Alarm System
Several types of warning are foreseen in the DAC-109: absence of data at the main channel, absence
of data at the reserve channel, absence of data at the main and reserve channel, absence of connection
to the synchro-receiver, the initial position of connected analogue repeaters are not entered (see
par.6.4).
Warning about Missing of Data at the Main Channel
If the converter does not accept data about the course through the main channel during the time, set by
the setting «Alarm Period» (see par.6.2), the audible warning is switched on, and if the setting
«Backup Channel» is set in «On», the converter is switched over to the reserve channel for receiving
data NMEA data.
Visually, the current state of warning is shown at the converter display in the standby mode as
follows:
If NMEA course data is also missing at the reserve channel, the converter display switches over to the
following mode:
Page 17
Unicont SPb Ltd Technical Documentation DAC-109
Page 17
When receiving of data through the main channel is renewed the audible warning is stopped, and the
converter is switched over to the main channel.
When the warning is switched on (while switching on to the reserve channel) the contacts of the
output RELAY are also closed).
Warning about Absence of Data at the Reserve Channel
If the setting «Backup channel» is set in «ON», DAC-109 controls receiving of data through the
reserve channel. When data at the reserve channel is missing, the mark «!» appears at the indicator in
the upper line, on the right from the value of course, accepted through the main channel. At the same
time the audible warning (beeps with duration of 0.5 s each 5 seconds) is switched on. Contacts of the
RELAY output are not closed.
Device overload alarm
In case of device output overload (such as short-circuit), DAC-109 automatically shuts the signal
conditioner to avoid damage to device circuits and connected equipment. Herewith the message
appears “Overload protection”. In order to restart the device, the cause of unit overload should be
eliminated and DAC-109 reset.

6.4 Entering Initial Positions of Analogue Repeaters
After its switching on, DAC-109 on default, thinks that connected analogue repeaters indicate course
«0°». If any other value is indicated at the repeaters, the shift which equals to this value when
converting the course will be generated. In order to prevent this effect, entering the initial position of
connected repeaters is foreseen in DAC-109.
In order to enter the initial course of analogue repeaters it is necessary to fulfill the following actions:
1. In the standby mode press the key [F1].
2. Enter the initial course (POSITION) of analogue repeaters (see example below). In order to
erase the entered value – press the key [SHIFT] and [CLEAR] (each pressing of [CLEAR]
erases the last symbol), in order to exit the mode of erasing – press the button [SHIFT] once
again.
3. In order to store the entered value press the key [ENTER].
Example of entering the initial value of course:
It is necessary to enter the initial position of analogue repeaters «340.1°».
[F1][3][4][0][SHIFT][.][1][ENTER]
It is necessary to enter the initial position of analogue repeaters «234°».
[F1][2][3][4][ENTER]
Attention! If the user did not enter the initial position of repeaters, instead of the value of course
for the analogue repeaters the line «---.-» is displayed in the lower line of the display. At the
same time, the converter does not process the changes of digital course, received from the signal
sources NMEA 0183.
6.5 Principle of Operation of the Converter
The converter accepts the digital value of course from the sources of signal NMEA 0183 and converts
it into sinusoidal voltages at the outputs for connecting coils of the synchro-receiver. At the same
time, the amplitude of oscillation is set in the way that results in the synchro-receiver occupies the
position corresponding the digital value of course.
Since some time is necessary for turning the synchro-receiver, which is determined by the number of
necessary turns (when the relation of the synchro turn to the turn of the ship is not 1:1) and the inertia
of the synchro-repeater, changing of course at the connected analogue repeaters takes place gradually.
Both courses (accepted and converted) are displayed at the converter screen (see par.6.1). If DAC-109
did not have enough time to move the connected synchro-receivers to the value of course, which was
accepted before, and got the new value, the converter is switched over to processing the new value (in
other words, DAC-109 always moves synchro-receivers repeaters to the last accepted value of course).
7. DEBUG TOOLS AND DIAGNOSTIC AIDS
7.1 Imitation of Digital Gyrocompass
In order to simplify the process of setting the converter and connected repeaters, DAC-109 is provided
with a special mode of imitation the digital gyrocompass. In this mode the converter ignores accepted
data about the course from the sources of signal NMEA 0183 and processes the values of course,
entered by the user from the converter’s keyboard.
Page 19
Unicont SPb Ltd Technical Documentation DAC-109
Page 19
In order to switch on the mode of imitation of the gyrocompass it is necessary to press the key [5] in
the standby mode. The Converter’s indicator is switched over to the following state:
In order to switch on the mode of imitation it is necessary to press the key [F1], in order to switch it
off (if it was switched on before) – press the key [F2]. After pressing the key [F1] the mode of
imitation is switched on, the report «IMIT HDG:» will be displayed in the upper line of the indicator
instead of the report «NMEA HDG:». In order to enter the course, which should be set instead of the
course accepted from the sources of NMEA signal, it is necessary to press the key [7], then to enter
the value of course (similarly to par. 6.4).
Attention! After debugging the converter and analogue repeaters connected to it, do not forget
to switch off the mode of imitation of the gyrocompass!
7.2 Imitation of Cyclical Turn of the Ship
The second mode which is necessary for simple debugging the connected repeaters – is the imitation
of cyclical turn of the ship. In this mode DAC-109 emulates a constant turn of the ship to the right
with the speed of 360°/min. Changing of course at the connected repeaters, if they are connected
properly, should occur with a constant speed without jerks or wobble and without changing the
rotational direction.
In order to start the imitation of cyclical turn of the ship, press the key [9]:
In order to switch on this, press the key [F1], in order to switch it off (if it was switched on) – press
the key [F2].
Attention! After debugging the converter and analogue repeaters connected to it, do not forget
to switch off the mode of imitation of cyclical turn of the ship!
Press any key to exit the status display mode of the output channels.
