Quick Start Manual
14 GHP 20 Installation Instructions
The following three connection diagrams are examples of different
situations you may encounter when connecting your NMEA 0183
device to the GHC 10.

➏
Green - Rx/B (-) Tx/B (-)
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 10, and leave the
white wire (Tx/B) from the GHC 10 unconnected.

NOTE: When connecting a NMEA 0183 device with only one
receiving (Rx) line, the NMEA 2000 bus and the NMEA 0183 device
must be connected to a common ground.
If your NMEA 0183-compatible device has only one transmitting
wire (Tx), connect it to the brown wire (Rx/A) from the GHC 10, and
connect the green wire (Rx/B) from the GHC 10 to NMEA ground.
