AIS 300 Wiring Layout: AIS 300 Connected to a Garmin Chartplotter
through NMEA 0183
AIS 300 receiver box
* The AIS 300 does not need to be installed alongside a VHF radio, but they can share the same VHF antenna if they are both installed
on your boat.
** The listed wire colors are for the NMEA 0183 Port 1 input on a Garmin GPSMAP 4000/5000 or GPSMAP 6000/7000 series chartplotter.
Refer to the installation instructions provided with your Garmin chartplotter if you want to connect the AIS 300 to a different model of
Garmin chartplotter or to a different NMEA 0183 port on a GPSMAP 4000/5000 or GPSMAP 6000/7000 series chartplotter.
If you are connecting the AIS 300 to a non-garmin chartplotter, see page 5 for detailed wiring assignments.
