Does anyone know if there is any way to get serial altitude data from G3X for Trigg transponder. It uses the normal Icarus etc..

 

[Brantel]

The normal link the G3X uses to talk to the Garmin xponders is dedicated and a hardcoded proprietary format. Not sure what that format is without sniffing the port and reverse engineering it.

I doubt it would work but you can ask G3Xpert to be sure.

And because the 23ES costs less than the Trig, it just doesn't make much sense to run a trig with the G3X.

The 23ES is a TSO'd unit, no different then the trig in that regard

I am using the King KT74, which is basically the TT31 trig manufactured for King. The install manual is the same as the TT31. The KT74/TT31 will not recognize the Garmin G3X output format. I tried using various settings to no avail. I ended up using the encoder output of the Dynon D6 I use as a backup instrument. This works fine, and coupled with the 403W ADS-B+ output passes all the ADS-B parameters.
I would really like to use the air data output from the G3X, but I see no way with the Garmin proprietary format.
