20 Setting Up the Projector
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. On the Pro Cinema 9700 UB, it can also
be used to operate a motorized anamorphic lens.
Connect a 3.5-mm mini jack to the port, as shown.
Use the
Trigger Out setting to enable the port (see
page 48).
■ 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 page 69.
