Nice writeup scotte! It clarifies some things I was unaware of....thanks.

I just wanted to add that with a NMEA 0183 multiplexer you can take two or more sources that generate NMEA 0183 data and send that data to a single display unit. In that sense, it is possible to combine two NMEA data streams into one steam. This of course means one direction only.

I have heard that NMEA 0183 is an ASCII sentence but with a higher voltage...is this true scotte?
