Listers,
I've tried sending two different sources of NMEA 0183 data at 4800/9600/19200/38400/57600 baud rates to my Garmin GTX-327 on both serial input ports 1 (db25 Pin 2) and port 2 (db25 pin 19), and configured for "GPS" input. But I don't get anything on the GTX-327 serial input test display. I have been successful at getting AirData Z-format from the GRT EFIS at 9600 baud into either of the GTX-327 serial ports, so the ports are good. The NMEA 0183 data registers correctly on other devices reading it so the GPS serial output seem fine. The GTX-327 just won't seem to see the GPS data for some reason.
Am I doing something wrong? Has anyone else tried this successfully?
Thanks!

Hi Matt,
Don't do it in "test" mode. It should be 4800 (IIRC) from the GRT, and then
setup the input on the GTX RS232 port. If you turn both on in normal mode
you should see the PressAlt on the GTX327. It's worked for us hundreds of
times!
Cheers,
Stein
