Blacksheep,
Actually I have asked because I found in Mode `S` transponder Installation Manual(Allied Signal) that both mode `S` trpdr`s are connected to ADC`s by Arinc 429 and also connected to encoding altimeters by Gillham connection ?
I already asked Allied Signal (Honeyweel) representative about this but steel don`t have answer. That`s a question.
