NMEA 0183 connection
The display can transmit and receive NMEA 0183 data when using a compatible NMEA 2000 to NMEA 0183 converter, such as the Actisense® NGW-1 converter (part number: A80721), connected to the same NMEA 2000 / SeaTalk NG network as the display.
Ensure all devices are powered off before making connections.
Connect the converter to your NMEA 2000 or SeaTalk NG network, using either a DeviceNet to SeaTalk NG adaptor cable, or a DeviceNet cable as appropriate. Then, connect the converter’s NMEA 0183 bare wires to the relevant wires on your NMEA 0183 device, and crimp and insulate the wires.
The details below are provided as an example of how to connect a device using the Actisense® NGW-1 converter (A80721). Depending on your NMEA 0183 device, you may require a different converter. The converter and device wire colors may also vary from those shown. Refer to the instructions supplied with your NMEA 0183 device and your converter to identify correct signal connections.

If your NMEA 0183 device is a version 1 device (i.e.: it only has 3 NMEA 0183 wires), the connection will differ from that described above. Please see below for alternative wiring:
