Transponder Control

Post by stubenflieger »

Hello,

I tried to find offsets for the transponder (Squawk, Mode, Traffic etc.)

Is there any value? I did not find anything in the documentation and offset list.

Thank you

best regards markus

The soft uses the squawkbox/vpilot offsets.

I tried but was not successful.
I can set the transponder code via offset 0354 from hardware to fsuipc but if is not updated in the MCDU if I call TCAS page. When I set the code via MCDU it updates the offset value (in FSUIPC & MCDU).

Next problem is the TX Mode (offset 7B91) I can set it through MCDU but when I want to change the value via hardware it always immediately jumps back to the MCDU's setting.

Additionally I did not find any offset for traffic and mode on squwkbox, but I fear it will be similar behaviour.

Did I do something wrong? Is there any setting I missed?

Thank you

Br Markus
