7.4.4.2 Transponder Interface Check
If the GTN is interfaced to a GTX 32/33 remote transponder or a GTX 327/328/330 configured as a remote
transponder, the following checks must be completed.
1. With the GTN unit running in normal mode and the transponder powered on, go to the Home page
and ensure there is no red ‘X’ over the transponder data field on the screen.
2. Ensure that a code can be entered into the code field. Enter a code using the keypad and then touch
the Enter key. Ensure the code that was entered is displayed in the transponder data field.
3. If dual transponders are installed, select Transponder 2 and perform steps 1 and 2 for the second
transponder as well. Also pull the Transponder 1 circuit breaker and ensure the Transponder 1 data
field is red ‘X’d rather than the Transponder 2 data field to verify that the wiring is not crossed.
(i.e. Transponder 1 is incorrectly connected to the GTN.)
Repeat the steps 1 through 3 for the second GTN.
