GHP 12 Installation Instructions

Example two of three - only one Receiving Wire

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.

Example three of three - only one transmitting Wire

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.
