Lowrance electronic LCX-20C manual Nmea 0183 Wiring Data cable

NMEA 0183 Wiring (Data cable)

To exchange NMEA 0183 data, this unit has one NMEA 0183 version

2.0communication port. Com port one (Com-1) can be used to receive NMEA format GPS data. The com port can also transmit NMEA format GPS data to another device.

The four wires for the com port are combined with the Power Supply cable and NMEA 2000 Power cable to form the power/data cable (shown earlier). Com-1 uses the yellow wire to transmit, the orange wire to receive and the shield wire for signal ground. Your unit does not use the blue wire.
