Only One Receiving Wire
If your NMEA 0183 compatible device has only one receiving
wire (Rx), you must connect it to the blue wire (Tx/A) from the
helm control, and leave the white wire (Tx/B) from the helm
control unconnected.

NOTE: When connecting a NMEA 0183 device with only one
receiving (Rx) line, you must connect the NMEA 2000 bus and
the NMEA 0183 device to a common ground.
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.
