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!

I'm not positive of this, but I think most Garmin stuff

will not work with NMEA 0183, only Aviation format. It

makes working with some things a bit tough.  So the

GTX-327 probably just doesn't understand it.

 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.
