Initially , on my IFD 440, the shop wired pins 37,38 from p1001 to my audio panel. I got nothing. After some research , it was rewired using pins 52, 53. The callouts / audio are working now. What are pins 37, 38 used for? The Installation manual shows as audio hi and audio low. I currently do not have ads-b /in hard wired to IFD 440, but that’s about to change. Once ads-b /in is to the IFD 440, will I get audio traffic alert outputs thru pins 52, and 53?
