Alencoder choice for XPDR Becker 6401

[innovair]

which message format 1 to 4 to choose on the EFIS function ALTENCOD to communicate with a transpondeur BECKER 6401
and how to setup the Becker 6401 to communicate with the Dynon (10 choice)

thank you for your help

It's most likely 4, but, their documentation does not specify the format, so it's hard to promise that that's correct. It looks like the becker can report the altitude it is receiving on the display, so, when you see the flight level on the display, you know you've found the right one.

I try most of the 10 becker mode mode but does work I will check again the wiring
