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).
