Connecting the GMI 10 through NMEA 0183

The GMI 10 can receive NMEA 0183 data from one device. The GMI 10 displays the received data, but cannot transmit the data to another NMEA 0183 device or transmit the data to a NMEA 2000 network.

Use the diagrams to wire a NMEA 0183 device to your GMI 10. Use 22 AWG, shielded, twisted-pair wiring for extended runs of wire. Solder all connections and seal them with heat-shrink tubing.

Wiring the GMI 10 to a Standard NMEA 0183 Device

Notes:

•Consult the instructions for your NMEA 0183-compliant device to identify the Tx/A(+) and Tx/ B(-) wires.

•When connecting NMEA 0183 devices with two transmitting and two receiving lines, it is not necessary for the NMEA 2000 bus and the NMEA 0183 device to connect to a common ground.

•The yellow (accessory on) wire and the black (accessory ground) wire are used only when wiring the GMI 10 to a Garmin GPS 17/17x antenna.
