Setting Up the Projector 21
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.
Use the Trigger Out setting to enable the port (see
page 47).
■To use an AV controller with the projector, connect a 9-pin null modem serial cable to
the RS-232C port. Refer to the table of ESC/VP21 command codes on page70.
