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.

1.5 MARKING AND SEALING
The nameplates, where the user can find a serial number, date of manufacturing,
weight, protection degree, input voltage and power consumption are located on the Prod-
uct’s casing.
The sealing of the Product and package is not provided.
1.6 PACKAGING
The Product is packed in a corrugated board box and inner packaging ensuring its
transportation and storage at the warehouse.
Transport packaging is also used as a returnable packaging for transportation of
the Product to the repair location and back.

2USAGE OF THE PRODUCT
2.1 OPERATIONAL CONSTRAINTS
The Product shall have proper grounding; all cables shall be insulated; non-insu-
lated / bare ends shall be absent.
2.2 USAGE PREPARATIONS OF THE PRODUCT
2.2.1 Safety features
While preparing the Product for usage observe it visually and check the absence
of mechanical damage.
Before the operation a user shall:
–train staff to use the Product and checkout equipment, as well as occupational
safety applicable in the field;
–check proper grounding;
–only use fuses recommended by the Manufacturer;
–switch the power off before disconnecting cables and replacing fuses;

2.3.1 Synchronization of compass card and character display readings
Synchronize a card and character display in case of readings mismatch; select
“SYNC”in the main menu and provide an adjustment of readings.
2.3.2 Settings of input and output channels
Select “CH1”in the main menu to set the parameters for the first input channel
and provide the settings of transmission rate, parity bit and number of stop bits.
Select “СH2”in the main menu to set the parameters for the second input channel
and an output channel and provide the settings of transmission rate, parity bit and number
of stop bits.
2.3.3 Settings of data sources
Select “SOUR”in the main menu to provide settings of data sources (Gyro, Mag-
netic, THD).
Individual settings can be provided for every data source: the user can detect input
channel number, set a NMEA sentence type (“HDG”, “HDM”, “HDT”), as well as switch
on / off checksum test mode.
2.3.4 Backlight brightness adjustment
Backlight brightness of card, character and LED displays in the course display
mode (Gyro, Magnetic, THT) is adjusted using “▼” and “▲” buttons. To increase bright-
ness press “▲” button; to decrease it - press “▼”.
Caution! The Product sets the last used level of brightness after powering on.
2.3.5 Selection of input data source
The current data source is displayed on the LED display located in the upper right
part of the Product. Use “F”button to switch to another source of input data in the main
menu mode.
Use the menu to provide settings of every data source.
Caution! The Repeater saves the last selected data source in case of powering off
(on).
2.3.6 Operating mode
The Product can have several operating modes:
1) course display mode is the main one for the Product;

Operating manual

2) use the menu operation mode of the Product to set the operating parameters.
When the Product operates in the second (2) mode, data retransmission and dis-
play of course data on a compass card and LED display stops. The backlight brightness
of character display and data source display (Gyro, Magnetic, THD) is set to the maxi-
mum. As soon as the user exits this mode, the brightness and operability are put into
normal status;
3) emergency operation mode to detect emergencies;
4) emulation (test) mode is used to check the Repeater’s system operability.
Once the Product is switched on it immediately transfers to the course display
mode. If the data transmission stops the Product switches over to the emergency mode.
To access the menu use “F”button.
Caution! Once the Product is switched on, it represents the last saved user set-
tings, backlight brightness level and selected source of course data downloaded from the
non-volatile memory.
2.3.7 Course display mode
In the course display mode the Product displays the input data on the card, repeats
these data on the built-in LED and retransmits them via an output channel
RS-232/422.
2.3.8 Main menu mode
The Product’s settings are carried out in the main menu.
To access the menu press and hold “F”button for 3 seconds, until you see “CH1”
