NMEA 0183 Connection Diagrams
These wiring diagrams are examples of different situations you
may encounter when connecting your NMEA 0183 device to the
helm control.
NMEA 0183 Connection Considerations
• The installation instructions provided with your NMEA 0183
compatible device should contain the information you need to
identify the transmitting (Tx) and receiving (Rx) A (+) and B
(-) wires.
• When connecting NMEA 0183 devices with two transmitting
and two receiving wires, it is not necessary for the NMEA
2000 bus and the NMEA 0183 device to connect to a
common ground.
• When connecting a NMEA 0183 device with only one
transmitting (Tx) wire or with only one receiving (Rx) wire, the
NMEA 2000 bus and the NMEA 0183 device must be
connected to a common ground.

NMEA 2000 bus and the NMEA 0183 device to connect to a
common ground.
Only One Receiving Wire
If your NMEA 0183-compatible device has only one receiving
wire (Rx), it must be connected to the blue wire (Tx/A) from the
helm control, and the white wire (Tx/B) from the helm control
must remain unconnected.

Only One Transmitting Wire
If your NMEA 0183-compatible device has only one transmitting
wire (Tx), it must be connected to the brown wire (Rx/A) from the
helm control, and the green wire (Rx/B) from the helm control
must be connected to NMEA 0183 ground.
