NMEA Translations

The WatchMate Vision, XB-8000 and XB-6000 AIS transponders support translations from NMEA 2000 into 0183 and vice versa. Not all sentences are supported though. To-date we have added the sentences that are most useful for navigation purposes and that compliment the transponder's safety features. This summary does not include all the AIS NMEA 2000 PGNs that are also transmit from the transponder.
