Anybody out there using a Garmin GTX 327 and showing a squawk code on the top bar of the Skyview Screen. Both Skyview manuals indicate the GTX can provide status. The GTX pin 20 (RS-22 out1) is connected to Dynon pin 3 Serial Port 1 RX. I have configured both Dynon and The GTX for this. I am getting the big red "X" covering the entire transponder status area. Any input would be great. Have been dealing with this issue to long.
