Encodeing from modual/transponder EFIS D100.

[hoursaway1]

I have a Narco 50A transponder wired to Dynon encoder modual to EFIS D100, is there anything I need to change, or turn on inside the D100 to enable the encoder feature, Lansing Aproach states no alt. reporting from my transponder. Thanks, David

The EFIS needs to be sending out altitude information in the right format for the encoder converter. Check that SETUP > ALTENC is set to Format 1.
