NOTE: When connecting a NMEA 0183 device 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.
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.
