NMEA 0183 wiring
HDS-5 & HDS-7 Data Cable
To exchange NMEA 0183 data, the HDS-5 and HDS-7 units have a NMEA 0183 version 2.0 (RS-422) communication port. Serial Communications Port one can be used to transmit or receive NMEA format data. The five wires for the serial communications ports (Data cable) are combined with the Power cable to form the Power/Data cable.
HDS-8 & HDS-10 Data Cable
To exchange NMEA 0183 data, the HDS-8 and HDS-10 units have either one NMEA0183 version 2.0 (RS-422) communication port, or two NMEA 0183 (RS-232) communication ports. The five wires for the serial communications ports (Data cable) are combined with the Power cable to form the Power/Data cable.
