________ As stated earlier, each input button can be programmed to “learn” an
associated IR command. For example, selecting the PC1 input could also
send a signal to the projector to switch to its computer input mode, and
selecting VID1 could cause the projector to switch to S-video mode, etc.

PC Input Selection Buttons and Indicators:
• PC1 – Input select button for computer video and audio. This selects the
input from the VGA and Audio connectors on the System 5 front panel.
• PC2 – Input select button for an RGBS or RGBHV source (and audio)
from the PC2 section of the rear panel. This could be from a computer,
through a computer-video interface.
• PC3 – Same as PC2 but input is from the PC3 section of the rear panel.
4
Composite or S-video inputs (VCR, DVD, etc.):
VID1 – 1st input select button for Composite Video or S-video with audio.
VID2 – 2nd input select button for Composite Video or S-video with audio.
5
Audio Gain (Volume) Control knob for amplified output.
Max LED (red) – lights when the audio output level control has reached its
maximum point. This does not indicate the audio level.
Clip LED – lights when the output level is beginning to overdrive (peak).
This indicator is used to set the audio attenuation for the inputs.
Min LED – lights when the output level control has reached its minimum
point. This does not indicate the audio level.
_______ When all audio inputs are at the same level coming into the System 5cr,
the Volume knob functions as the master volume control for both audio
outputs. (See Setup Mode procedures later in this chapter.)
6
PC1 Input connectors – Audio and Computer VGA connectors selected
by the PC1 button. Connect a VGA cable to the 15-pin HD connector.
Plug the computer’s audio output to the audio jack.
_______ Each of the controls described above are duplicated on the IR 40 remote
control, on the optional SCP 100 panels, and on the Windows® control
software. The operation is the same, including associated IR commands.

IR Function LEDs and Infrared Receiver/Learner Port – In addition to
each LED having its function, in combinations they indicate other things.
TX LED (green) – lights when System 5 is transmitting infrared signals.
Flashes with Config and Retry LEDs to indicate a time-out condition
for the configuration mode.
Config LED (amber) – When steady on the System 5 is in setup mode and
is ready to be configured. See the Setup Mode procedures for ways in
which this indicator is used in combination with other LEDs.
Retry LED (red) – Indicates the System 5 has failed to recognize a command
in the infrared learning process.
IR Remote – window receives signals from the IR 40 for normal operation, as
well as from other remote control sources when learning commands.
