Well i had some success today. I downloaded some free
GPS software that was not much use for
navigation as far as i could see - but it did hellp me identify which COMM port was in use, and see
NMEA sentences. It turned out to be port 6. So I loaded up Ray tech 4.1 (using Windows 7) selected COMM port 6, messed with baud rate (set it to 4800), and it worked. I can now see all my instruments except
radar. I am not sure if my plotter puts
radar data on
seatalk or not, so will have to do a bit more
research on that - or try moving from the
dock and see if that makes a difference, as it was saying it could not find my heading. Anyway, seems like significant progress.
