Application 2: Controlling Projectors that Require Power Off Confirmation

Some projectors controlled via IR require the Power Off button on the hand-held remote control to be pressed twice to turn off the projector. These projectors usually present

a prompt (similar to the one shown below) on the image, instructing you to press the Power Off button again to confirm your intent to power off the projector. (If the projector is controlled via RS-232, this prompt is usually not displayed.)

Turn Power OFF?
