I just purchased a new 9200 hd and I installed the Illumi 8psk board.My question is the board came with a short cable ( like the cable coming out of the wall ). The board has a inlet connector which I screwed in. What actually inputs into that connector. Does the short cable connect to it and to what on the back of the 9200. I would think that sat in would go there ,but have no directions.Can anyone help.
