Installing the projector 51
TIP: As an alternative, you can loop a cable or bracket around the projector handle to secure
the projector in place.
Controlling an external accessory
If your projector has a 12-volt trigger output port, the projector can automatically control one or
more accessories. Certain types of accessories can use a 12-volt signal to trigger their actions,
such as a motorized screen lowering and raising the screen. The output provides a 12-volt dc
signal whenever the projector is on (200 mA maximum current output).
Requires:
• Two-wire cable with 3.5-mm × 1.3-mm barrel connector (12 V on inner contact)
