Hi UH,

The key is knowing that the Cambridge GPS-NAV only sends data out the 9-pin
serial port if the attached device tells it to start sending data. The SN10
doesn't do that. Therefore, you must connect the SN10 to the GPS-NAV's
6-pin DATA port. That port always sends the GPS data at 4800 baud. The
transmit and ground wire connections are detailed in the GPS-NAV manual.

I'm trying to get Model 20 to communicate with SN-10B.
We know we have connection cable right.
Logger is on- 2 different 20's tried.
We get "No GPS input" and "No message received from GPS" messages.
NMEA input is selected.
Any help appreciated.
Thanks
UH
