@q2g2000cwa.googlegroups.com:

I know that there
are many models of gps/ploters that are AIS enabled,

That all sounds good until you look at what comes out of the AIS at
38,800 baud RS-232 level data....then look at the GPS/Plotters plodding
along on RS-422 (NMEA-0183 isn't RS-232C compatible) at 4800 baud.....

You need to get your facts straight! A Raymarine C/E series chartplotter
runs at 38400 baud when in AIS mode. Most likely others do that too....

Oh and besides that, there is also something called NMEA0183-HS which IS
38400 at RS422.
