hello cruisers forum... gps qnd open cpn wont communicate

[honeybee616]

;;;ive been reading as many historical threads as possible on this issue:::but of course im still stuck!.... can anyone please help?

globalsat gps receiver bu 353 S4 connected to laptop via usb
open cpn 4.0.0
windows 7.0 os
iridium sat phone connected via usb also

when i check the gps receiver the very first thing is that it defaults to the sat phone com port when i open it ... i cant find a way to save the option to default it to the gps receiver com port

next when i change this option to the gps receiver com port and click start gps...it seems to be functioning correctly ....the satellites are being found and data is running. (when i check in device manager - ports - i see that the device is installed correctly and working correctly)

in open cpn i have added the connection - this is what the screen reports - com10 (same as in device manager- ports); baud rate 4800; connection input; filters In None; Out None (is this part of the problem??)

also nmea debug window is blank with just legend displayed

i will stop for now but if any more information is needed please ask away .....any help or assistance from this group is very much appreciated

1. Disconnect the sat-phone for now. Get OpenCPN running correctly first, and then add the phone back into the mix.

2. The Globalsat BU353 needs no additional user program to run with OpenCPN. It needs just the driver which it seems that you have.
So, whatever program you are running to do this:

quote:
"when i check the gps receiver the very first thing is that it defaults to the sat phone com port when i open it"

.and this:
"next when i change this option to the gps receiver com port and click start gps."

is not required for OpenCPN, and in fact interferes with OpenCPN.

What program is that?
