Wiring Additional NMEA 0183 Devices

The NMEA 0183 data cable included with the GPSMAP 6000/7000 series chartplotter supports the NMEA 0183 standard, which is used to wire various NMEA 0183-compliant devices, such as VHF radios, NMEA instruments, autopilots, or a computer.

Basic NMEA 0183 Wiring

These diagrams illustrate basic NMEA 0183 wiring used to connect your GPSMAP 6000/7000 series chartplotter to NMEA 0183-compliant devices such as an AIS or DSC device. For more-complete information on the NMEA 0183 capabilities of the GPSMAP 6000/7000 series chartplotter, see the “Advanced NMEA 0183 Wiring” section (page 13).

Wiring to a Single-ended NMEA 0183-compliant Device

Notes:

•If the NMEA 0183-compliant device has only one receiving wire (no A, B, +, or -), leave the pink wire unconnected.

•If the NMEA 0183-compliant device has only one transmitting wire (no A, B, +, or -), connect the orange/white wire to ground.

•Consult the installation instructions of your NMEA 0183-compliant device to identify the Transmit A(+) and B(-) wires and Receive A(+) and B(-) wires.

•Use 28 AWG, shielded, twisted-pair wiring for extended runs of wire.

•Solder all connections and seal them with heat-shrink tubing.
