Model: NM-251A
NMEA Buffer Splitter |
NM-251A is a two channel input/five channel output NMEA-0183 multiplier with input priority encoding. It enables data distribution from two NM-0183 sources (primary and secondary with priority encoding) to all NMEA-0183 instruments through four or five talker ports and PC connection through the RS-232 port.

Model: NM-251A-MUX
NMEA Buffer Splitter with dual input multiplexer |
NM-251A-MUX is a two input channel multiplexer with five output channels NMEA-0183 data multiplier. It enables combining and multiplying of NM-0183 sources to all navigational instruments through five talker ports and PC connection through RS-232.

Speed Log Interface |
NM-251B is a Speed Log ppm output to NMEA-0183 converter that enables connection of every speed log that uses the “closing” contact interface with digital systems and instruments that comply with the NMEA-0183 standards. The NM-251B is capable of converting the speed log contact closures to a standard NMEA $VWVHW string with checksum error control and output at TTL, RS-422 and RS-232 signal levels.

NMEA Baud Rate converter |
NM-251BRC is a baud rate converter that allows interconnection of talkers and listeners with different baud rates
NM-251BRC has five general purpose output ports that are able of transmitting NMEA sentences in both RS422 and TTL signal levels, depending on the connection topology and each one can fan out one instrument. Certificates |
