I have an Elunevision Tab Tensioned Motorized screen with a Panasonic projector. I connected the remote trigger to a femal to male mono mini plug extension cable and plugged that into the projector. It works flawlessly. The projector has a built in delay that doesn't send the 'down' signal until it has warmed up, about 45 seconds or so. When shutting off it sends the 'up' signal immediately.
