20 Setting Up the Projector
■
The
Trigger out
port(s) output 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.
Depending on the setting you select (see page 45), it
can also be used to operate an anamorphic lens.
Connect a 3.5-mm mini jack to the port, as shown.
■
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 74.
Installing Batteries in the Remote Control
The remote control uses two AA manganese or alkaline batteries.
Warning: Keep batteries away from children. If a battery is swallowed, contact your doctor
immediately.
1. Release the tab and lift open the cover.
2. Insert two new AA batteries as shown.
3. Insert the tab on the cover and press it down until it
clicks into place.
Aim the remote control at the screen, or at the front or
back of the projector. Make sure you are within 30 feet
of the projector.
If you suspect the batteries are weak, press the
illumination button. If the buttons do not glow,
replace the batteries.
