I used that and another image that Elite Screens sent. It shows that the first two wires in the RJ-45 connector are the 12v and ground...as does that image pin layout. What I did was take a standard Cat5 (RJ-45) cable and used the two wires that provide the 12v and Ground. At the projector (20 feet away) I've tried soldering a mono tip on the 2 wires from the Cat 5 and could not get it to work. I also took another mono 3' cable and cut one end off and twisted the wires together for testing. Neither were successful.
When I place a 9v battery on the wires the screen lowers as expected and when I remove the battery the screen retracts as well. But when I use a 3.5mm cable into the projector, it doesn't do anything on power up/down. I have it set as Power ON - Output. So it should be sending a 12v charge down into that trigger port.
Since the screen functions via the 9v battery I'm going to assume everything is correct on the screens end and it's something else on the projector side.
Any ideas or suggestions?

That is what I used. It shows the brown and brown/white wires as being the ground and 12v. That is what I used it functions properly if I use a 9 volt battery, but hooked up to the Projector...nada.
