hmmm. tried a print screen
to show you the GPS window but nothing appeared when I tried to paste here.
in GPS window I got to chose port (COM4) and Baud rate (4800). When I start the GPS there are just streams of lines that circle up the page
in the OpenCPN window Im asked to filter NMEA
course and filter period (1)
under properties i chose serial
and port and priority (1).
then I can accept "checksum" or use garmin
. I chose checksum
finally I can accept only sentences or ignore sentences
Does this help. Or do you know how I can cut and paste into this message
