Activate aux com on HDX

[DY691]

Hello everyone,
I have installed a traffic detector called Superneurone in my aircraft.
In order to receive audio warnings, I need to activate the auxiliary audio input. My aircraft is equipped with Dynon HDX, which includes a Trig radio.
I haven't been able to find how to activate the auxiliary audio input on the various pages...
If anyone can tell me how to do this,
I'd be very grateful.
Guy

You don't say what model Trig VHF you have, But I will assume a TY91 or a TY96

On a TY91, connect your alert audio HI to pin 20 of the main unit connector.

If it is a TY96, then connect to Pin 14

Thank you, GKC Aviation, for your help.
I have successfully connected the superneuron to pin 20 on my radio, but there is no sound in the headset.
I am trying to find out how to activate or adjust the volume of the auxiliary input as indicated on the following page via the HDX.
