________ In addition to the basic function of each of the panel buttons described
here, there are also setup procedures that use many of the same buttons
and controls. Each of the Input and Display buttons is capable of
“learning” an IR command. The Display Power button must learn both
power on and power off for the projector. The setup procedures are
described later in this section.
Front Panel Controls and Indicators
On power up, all of the LEDs light and then go off, except for the Power
LED and the LED for the input last selected. On the rear panel, the LED
for the selected input format will be lit.

Power and Room
Power LED – Indicates when the System 5 has power.
Room Button and LED – These work with the relay contact connections
provided on the rear panel of the System 5. The button can activate/
deactivate a room condition, such as turn lights on/off and raise/lower a
viewing screen. The LED indicates that the condition is active. Exactly
how the feature is used depends upon the user-defined application and
what is connected to the “Relay” connector on the rear panel.
Figure 3-1a. Front Panel Buttons and Indicators
The Room button can be set to operate in either of two ways: latching
(press on, press off) or momentary (press on, off after time-out). The time-
out value can only be set through the Windows® Control Program.
_______ For example, pressing the Room button once could lower a screen and
turn room lights off and the LED will remain lit. Press the button again to
turn the room lights on, raise the viewing screen and the LED goes out.

Display – (customized for the projector being used)
________ These buttons only function after being programmed, either by “learning”,
or by loading the projector’s commands from Extron’s IR library. Learning
is described in the Setup Mode procedures later in this chapter.
Power – After this button has been programmed for the projector’s IR
remote commands, it will toggle power to the display device on or off.
Because there is a warm up delay and a cool down delay for many
projectors, the Display Power LED will blink fast during projector
power up and will blink slowly during projector power down. The
blinking time is generated within the System 5; it does not come from
the projector. Its duration can be programmed through RS-232.
Mute – After this button has been programmed for the projector’s video
mute signal, it will function as the Display Mute on/off switch.
Mode – Effective on display devices that do not automatically detect the
type of video signal, this button can be programmed to change the
mode of the display device between computer-video, composite video
and S-video. This can duplicate the single-button (step) mode function
found on some projector remote controls.
