Basic NMEA 0183 Connections
These diagrams illustrate basic NMEA® 0183 wiring used to connect your device to NMEA 0183-compliant devices. For more information on the NMEA 0183 capabilities of the device, see Advanced NMEA 0183 Connections.

-
If the NMEA 0183-compliant device has only one input (RX) wire (no A, B, +, or -), leave the pink wire unconnected.
-
If the NMEA 0183-compliant device has only one output (TX) 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 output A(+) and B(-) wires and input 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.
