Data cable wiring diagram: HDS-8 & HDS-10 units

NMEA 0183 wiring (data cable)

To exchange NMEA 0183 data, the HDS-8 and HDS-10 units have a NMEA 0183
version 2.0 (RS-422) communication port. Serial Communications Port one (Com
1) can be used to transmit or receive NMEA format data. Two RS-232 ports (Com 1
and Com 2) also are available via software selection. These ports transmit or receive
NMEA data.
The five wires for the serial communications ports (Data cable) are combined with
the Power cable to form the Power/Data cable.
• Com 1 (RS-422) uses the yellow and blue wires to transmit, the
orange and green wires to receive and the shield (bare) wire for
signal ground.
