Da-Lite Radio Frequency/RS-232 Screen Control Accessory

This is the interface that puts a Da-Lite motorized screen on a control system. It adapts the screen's low-voltage control line to RS-232, so a Crestron, Extron or AMX processor - or anything else that can open a serial port - drops the screen when the projector fires and takes it up at the end of the meeting, with no separate wall switch in the sequence.

Da-Lite lists it for Wireline (120 V), Studio and Arena screens, and the cables and adapters needed to make the connection are in the box. It sits in the same accessory family as the radio-frequency single-channel wall switch, the dry contact interface and the RF range extender, which are the pieces you add when a room needs handheld or contact-closure control alongside the serial link. Da-Lite part number 29243.
