Anibody can tell me the diferences betwen V3.1 and V2.0? Or better,
who have the NMEA 183 specs can send me a copy? I read somewhere that
the V 3.1 alows for more than one talker: this is true?

I am interested specifically in the RMB, RMC, BWC, XTE, DSC, DSE, to
interface autopiots and VHF/DSC radios.

Thanks
