The Actisense NGW-1 is a great device for converting NMEA 0183 to NMEA 2000 (and vice versa).
The NGW-1 Conversion Lists below detail all of the conversions that can be performed by the NGW-1 and just as importantly those that cannot.
Notice there are two conversion lists, one for the standard firmware, and one for the AIS firmware. The first one shown is for the standard version of NGW-1 firmware.
