To clarify: This voltage (12V) tip to shield , indicates the processor port is an "output"
If so it will not serve my purpose which was simply "to trigger on the video hqv processor" from my AVR.
Again.....Epson told me this was an "in" not out but I think they are wrong.
It is unusual (in this industry), but Epson could be correct. It is possible that the sense of things is inverted and that grounding a pin with voltage is interpreted as “true” input. While I haven’t seen it in this industry, I certainly have not experienced all possible products.
Bottom line, one can only be sure if one has proper documentation.
It’s a cruel world and Mother Nature holds all of the high cards.
