A quick over view http://en.wikipedia.org/wiki/NMEA_0183
more details http://gpsinformation.org/dale/nmea.htm Because NMEA is plain ascii text you can send it to a text file and read it to see what you are getting . Devices do not send all posable sentences they send a subset or maybe 8 or 12 or less every second. Many devices allow you to program the subset that is actually sent. I once owned a sailboat that had a dozen NMEA compatible devices. It took some effort to find a common subset. GPS, wind sensors, water speed sensors, radars and autopilots all use NMEA Another good source of information is the manufacturer's web sites. Not just GPS makers but any marine electronics that uses NMEA, the data will be in some apendix of a user manual On Tue, Nov 30, 2010 at 5:29 PM, Jim Conley <[email protected]> wrote: > I have a copy of NMEA 0183 Versions 2.30 and 3.00. > > I will send any specific information on a sentence or sentence structure, > however I will not copy a complete page.
