FYI if you have purchased an Elite projection screen (https://smile.amazon.com/gp /product/B01MQYTSGW/ ) and you want it to go up and down when you turn the projector on and off, this cable is half the answer, it connects to the screen. The other half, which connects to the projector's "trigger out" is a 3.5mm 1/8 mono audio jack (e.g. https://smile.amazon.com/gp/product /B075SV1RHT), and you cut the cables and connect them together.
