Data conversion and distribution devices

NMEA buffer, amplifier, distributor and multiplexor

MDU-102 / МДУ-102

NMEA buffer, amplifier, distributor and multiplexor

The MDU-102 is designed for the multiplication of NMEA 0183 signals, version 1-3 (IEC 61162-1, 61162-2) or other serial data transmissions via RS-232 and RS-422/485 interfaces from one or two sources. The unit provides a checksum test for data received on the first channel.

NMEA 0183 signal multiplicator

ADU-202 / АДУ-202

NMEA 0183 signal multiplicator

The ADU-202 is designed for the amplification and multiplication of NMEA 0183 signals, version 1 and 2, or other serial data transmissions via RS-232 and RS-422/485 interfaces. An integrated summarizer combines the input NMEA 0183 sentences and transmits the results to one or two output groups, depending on the jumpers’ position on the printed circuit board.

Bidirectional RS-232/422 converter

RS-104 / КИ-104

Bidirectional RS-232/422 converter

The RS-104 interface converter is designed for the signal conversion between two standards: RS-232 and RS-422. It is the solution to combine equipment operating with RS-232 or RS-422 signals on river- and sea-going vessels.

Data combiner (4 outputs, 8 inputs, USB)

NC-117 / СД-117

Data combiner (4 outputs, 8 inputs, USB)

The NC-117 receives NMEA 0183 messages via eight RS- 232/422 inputs and 1 USB port. It combines the received messages according to the customer settings and repeats them via four RS-232/422 outputs and 1 USB port.
The unit will combine sentences of standards, starting with $ or ! or # and ending with and («carriage return» (CR) and “line feed” (LF) symbols).

Data combiner (4 inputs, 12 outputs, 2 iputs/outputs, USB)

NC-217 / СД-217

Data combiner (4 inputs, 12 outputs, 2 iputs/outputs, USB)

The NC-217 receives NMEA 0183 messages via four RS-232/422 inputs, combines them according to the customer settings and repeats them via twelve RS-232/422 outputs. Two additional bidirectional service ports and 1 USB are provided.

Multipurpose data converter

DFR-118 / УКД-118

Multipurpose data converter

The DFR-118 data converter is designed to process received NMEA data and repeat them to units connected to the converter output port. Depending on the software used, the unit is capable to filter and change baud and frequency rate of the data stream, adjust letter and digit of the NMEA sentences and add a checksum.
