The wiring harness connects the device to power and NMEA^® 0183 devices. 6-inch devices can also use these wires to share user data, such as waypoints and routes.

If you are not connecting NMEA 0183 devices or another chartplotter to share data, disregard the blue and brown wires.

The device has one internal NMEA 0183 port that is used to connect to NMEA 0183 compliant devices.

If it is necessary to extend the power and ground wires, you must use 0.82 mm² (18 AWG) or larger wire.

If it is necessary to extend the NMEA 0183 or alarm wires, you must use .33 mm² (22 AWG) wire.
