NN3D doesn't offer AIS via NMEA 2000. It works via network or NMEA 0183. Don't think that will ever change. It is possible to use the IF-NMEA2k2 to take a NMEA 2000 AIS unit into your 0183 NMEA port. The NMEA 2000 port Monitor tool will normally show items it sees on the network, but that doesn't mean it will accept the data it supplies. Sorry guys.
