Isn't NMEA 0183 going to be the same for both the GPS and the Flux Gate..

I have the Serial port set at 4800, 8 bit, no parity and one stop bit. That
works fine with any of the three GPS I have available..

I leave these setting and connect the port to the Flux Gate Compass and get
nothing.. In the absence of info otherwise, I would have to assume that it's
output would be this standard output for NMEA 0183..

It appears (or I haven't found) any control over these out put setting from
the Flux Compass. The only NMEA 0183 info in the manual has to do with the
two data lines on the DIN connector: SIGNAL and RETURN Data Output.

In the specifications it states: DATA OUTPUT-- NMEA 0183: HCHDM(heading),
HCBOD(course), HCXTR(deviation).

Still wondering ??
