Can anyone tell me if the Pressure Altitude display on the GTX-327 should change as I change the altimeter setting on my GRT HS? I have the GRT wired from pin 1 to pin 19 on the GTX-327 as per the manuals. I also have the GRT set to 9600 baud and Fuel/Air Z format for Serial port 6. On the GTX-327 I have it set to FADEC w/ ALT on RS232 Input Ch 1. Altitude is displayed on the transponder but does not change as I change the altimeter setting.
