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.

It was not in the wiring. The problem was not finding info to guide us to the required menu page in the SN10 to set the baud rate. Dave's guidance led us to fiddle until we found the setup page.
This was a case where RAS was very prompt and useful to get through a problem.
Thx
