1DESCRIPTION AND OPERATION OF THE PRODUCT
1.1 DESCRIPTION
The Product displays the vessel‘s course data received in NMEA 0183 standard
sentences (hereinafter referred to as –NMEA) from various digital sources using a card
and LED indicator. The Product rebroadcasts input NMEA data through an RS-422 in-
terface.
The Product is designed for sea- and river-going vessels, and industrial applica-
tion.
The Product’s detailed specifications, environment conditions, overall and instal-
lation dimensions are represented in Technical description of the Product.
1.2 TECHNICAL SPECIFICATIONS
The Product ensures:
display of three NMEA data types: “HDT”, “HDG”, “HDM”;
display of ship’s course data;
equipment interfacing via two asynchronous serial galvanically isolated ports,
RS-422 and RS-232 (with NMEA standard support);
input data retransmission to external ship systems from the selected ports;
the Repeater is controlled using the relevant buttons on the front panel (menu
access / exit, screen backlight brightness adjustment, switching of data sources);
manual adjustment (using control buttons on the front panel) of backlight bright-
ness level (14 levels totally).
1.3 OPERATION OF THE PRODUCT
The Product’s operation (processing of input ship’s course data) is ensured by the
controller. The receiver transmitters of interfaces RS-422/232 ensure the data reception.
The card display provides a user-friendly data presentation and consists of a card,
stepper motor, encoder and character display for digital data. The card has a built-in LED
display (Gyro, Magnetic, THD), which shows the selected source of course data. Use
three buttons “F”, “▼” and “▲” to control the Product. The functional diagram is repre-
sented in Figure 1.

Figure 1 –Functional diagram of the Product
The Product has two input channels. Each channel can have an individual config-
uration which is carried out using the configuration menu. The main sources of the course
data are gyro compass, magnetic compass and satellite compass.
The Product’s operation can be configured for a certain data source. The settings
in this case include the following:
defining a number of the input channel;
setting NMEA sentence type “HDG”, “HDM”, “HDT”;
switching on (off) a checksum test mode.
The Product receives and processes the input course data according to the selected
settings, represents the data on the character display, which is located in the lower left
corner and then - on the card.
The Product may be used as a repeater (to retransmit data).
The input data are retransmitted via the output channel RS-422.

nel”, see Figure 1 retransmits only input data of the active channel according to the con-
figured parameters of the selected course data source.

Operating manual
Page 14
Caution! Input “СH2”and output “OUTPUT”settings (transmission rate, parity
bit check, a number of stop bits) comply, as one receiver-transmitter unit is used; there-
fore, retransmission occurs under the settings provided for the second input channel
“СH2”in the configuration submenu of the second channel.
2.3.13 “SYNC”mode to synchronize the compass card
“SYNC”mode allows for synchronizing the data of compass card and character
display in case of their mismatch.
Access the submenu “SYNC”to carry out synchronization. Compass card will be
set to the specific position. Wait until the compass card stops. The character display will
show the previous saved synchronization value. If the readings of character display and
compass card mismatch, set the current value of the compass card using “▲” and “▼”
buttons. Press “F”button. The synchronizing value will be recorded to the non-volatile
memory; The Product will exit the synchronization mode.
Description of the controls in the “SYNC”mode:
“F”–to save the selected values and exit the synchro menu;
“▲” and “▼” –to set the present position (degrees).
2.3.14 “TEST”simulation mode
“TEST”simulation mode ensures emulation of the Product’s operation mode with
no input data. During emulation the character display and compass card represent the
periodic course value. The current mode ensures periodic 1 Hz frequency data transmis-
sion in format:
“$HEHDT, xxx.x, T*hh<CR><LF>”,
where
xxx.x –is the current course value in the simulation mode;
hh –checksum CRC;
“<CR><LF>” – end of line (carriage return and line feed).
Parameters of the output channel “OUTPUT”which provides transmission com-
ply with the settings of the input channel “CH2”.
Select “TEST”in the main menu to switch the simulation mode on and then press
“F”.
Press “F”again to exit the simulation mode.

2.3.15 Light alarm
2.3.15.1 Emergency operation mode
Once the input data are invalid or not compliant with the configured format or
data are no longer received, the Product switches to the emergency mode.
2.3.15.2 Light signaling
When the emergency is detected, the Product operates in the emergency mode.
Compass card backlight starts flashing; character display shows “----”, see Figure 4.
Figure 4 –Data are absent
Press any button to deactivate the backlight flashing.
After deactivating the Product will still operate in the emergency mode with the
character display showing “----”.
2.3.16 Recovery
To return the Product to normal operation, choose one of the following solutions:
1) fix the equipment which caused the stop in data transmission; restore transmis-
sion of the course data;
2) change the settings in case the current Repeater parameters and data format are
not compliant;
3) switch to the backup data source using “F”button .
Once the emergency is eliminated, the Repeater switches to the course display
mode.
