Then, this being the case, then this input to the radar it should be ok
since the compass sensor input is designated as DATA- H and DATA-C.

BTW. Would this NMEA level (0V and 5V) be compatable with your
multiplexors?? I kinda assumed so..

Hi Steve, I was just preparing an answer to your e-mail.

You mentioned a CLOCK-H and a CLOCK-C too, didn't you? That would make me
think that the heading sensor input expects something proprietary, since
NMEA does not use a clock. Can you, just for a test, connect the fluxgate to
the NMEA data input instead of the GPS?

My multiplexer inputs are NMEA compatible, effectively 'eating' anything
between 2V and 30V.
