Making Other Connections

Connect the power cable and other cables described below, depending on how you plan to use the projector.

■Plug the power cable into the projector and a grounded electrical outlet.

■The Trigger out 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. To enable the port, turn on the Trigger Out setting (see page 47).

■To use an AV controller with the projector, connect a 9-pin null modem serial cable to the RS-232Cport. Refer to the table of ESC/VP21 command codes on page 69.
