NOTE: 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.

If your NMEA 0183-compatible device has only one receiving wire

(Rx), connect it to the blue wire (Tx/A) from the GHC 20, and leave the

white wire (Tx/B) from the GHC 20 unconnected.
