Fellow pilots,
This is going to be the thread for HS34 wiring questions. Please understand that the product is not shipping yet and we cannot support all configurations. We'll do our best to answer what we can here.
DO NOT call our tech support line about the HS34 wiring yet. They are not trained on how it connects and don't have any additional info. This thread is supported by the engineer designing the HS34, so you should get some pretty solid answers
So here we go:
The HS34 has two D25 connectors on it. The upper one is male on the HS34 and is power, DSAB, etc. The lower one is female on the HS34 and is the ARINC and analog resolver interface.
Upper D25, male on HS34, female connector.
