Hi all,
I have a GARMIN GTX 335 with integrated GPS and GARMIN GAE12. The GPS and the GAE12 are working fine. The transponder is not working at all.
Directly after power-on I got the following message: "TRANSPONDER FAILED"
Pressing the buttons "ALT", "SBY", "VFR" has no effect.
Under "MESSAGES" there is only the following entry:
"1090ES ADS-B OUT FAILED"
An aviation engineer successfully checked the antenna (RAMI AV-74) and the antenna cable. He also reviewed the wiring. Unfortunately he did not found an error.
The GTX335 device was also tested outside the airplane with another antenna and another power source. The failure still exists.
hardware p/n and versions:
XPDR: p/n 006-B1607-09, version 2.12
GPS: p/n 006-B1827-00, version 6.0
ALT: p/n 3T6005914
pin assignment (P3251):
configuration:
Has anyone an idea?
Thank you!
Pascal
