Tiny Case Design
All circuitry is contained within a robust standard D-type 9 pin connector for the optimal design size and cost.
Galvanic OPTO-Isolated NMEA 0183 Input
Isolates the NMEA 'talking' device supplying the data from the attached equipment's receiver (computer or radar etc.). This prevents the potentially damaging voltage or current spikes present in the electrically noisy environment of the vessel's wiring network from reaching the attached equipment's receiver, and also stops any problematic ground loops.
Alternators, motors etc. can induce or conduct very large voltage and current spikes into the vessel's cables; computer ports (serial, USB etc.) are only designed to handle low voltage and low current signals.
TransZorb Protected RS232 Input
Prevents static spikes from the NMEA 0183 network damaging the attached equipment's transmitter (computer or radar etc).
Fast Data Baud Rate
Capable of data transfer rates up to 56k Baud.
Full Duplex (two-way) Communication
Using a full 4-wire interface, the attached equipment can receive the NMEA 0183 data transmitted by the NMEA 'talker' device (e.g. depth sounder, NMEA multiplexer etc.), and also send NMEA 0183 data back to the same NMEA device.
Fully NMEA 0183 Compliant
Complies with all aspects of the NMEA 0183 standard communications protocol.
The adapter cable's internal circuitry is self-powered from the RS232 (PC) serial port - no additional power supply connection is required.
Twisted Pair Cable
1.5 metres (5 feet) of high quality 4-core cable for noise interference cancellation / rejection.
