a new AIS blackbox, I'd
like to get AIS information on the Garm292 apart from ofcause to be
able to control the Gram292 from the PC for up/downloading.


Look carefully at the AIS black box manual. Notice how it says it runs at
ONLY 38,800 baud (bits/second)? NMEA is 4800 baud and won't go 38,800
baud. The Noland multiplexer has an OUTPUT you can get 38,800 baud OUT of,
but no INPUT to feed the 38,800 baud AIS black box INTO. Why AIS boxes
meant to be plugged into a BOAT, 99% of which are running 4800 baud
NMEA0183 V2 or 3, doesn't run 4800 Baud NMEA data output probably isn't a
mystery. NMEA wants big LICENSING FEES for their turf and the Chinese AIS
manufacturers didn't pony up.

I'm staring at how to interface it all on Lionheart with AIS. It sucks.
