This past weekend I put up my new Grandview 106 tab tension screen. It looks great!! The only issue is that it doesn't have an input for the projector 12v remote.

From what I can tell this screen, and most electric screens out there, have 3 wires. 1 common and two live ones, if 110vac power is applied to common + wire A the screen goes down. If power is applied to common + wire B the screen goes up.

So I'm thinking that to make the projector control the screen all I need is a 12v relay right?. Elite sells a controller for a mere $100 but I think a relay would probably cost me a few dollars.

Has anyone made this connection and if so how?

Thanks
