■ Control (RS-232C), USB, or network port

■ Trigger out port
This port outputs a 12-volt DC signal when the projector
is turned on. This lets a central control system monitor
whether the projector is on or off, and can be used to raise
or lower your projection screen automatically when the
projector is in use.
Connect a 3.5-mm mini jack to the port, as shown.
Installing the Cable Cover
Once you’ve connected all the cables, you can install the cover to conceal them from view.
1. Turn the projector upside-down.
2. Press the cover firmly into place, as shown.
3. Tighten the thumbscrews on the cover, then
return the projector to its upright position.
Note: If the projector is to be ceiling-mounted, you can change the direction of the EPSON logo
plate. Use the eraser-end of a pencil or similar tool to push in on the side of the plate closer to the
ventilation slots. Rotate the plate as needed, then press it back into place.
