 (SCP/AAP A only) — Press this

button once to select the specific input designated via the SCP/
AAP A’s rear panel DIP switch.  The LED next to the Show Me
button lights when that input is selected.  The switcher’s
corresponding LED also lights.

 — The

settings of the display control functions are customized for each
projector.  These buttons function only after they have been
programmed on the System 7SC or System 5cr Plus.

 — Pressing this button

turns the projector’s power on/off.  It may also be tied to a
Room function (System 7SC only) if programmed to do so.

The LED lights when projector power is on, and it blinks
during projector power-up/power-down.  The power-up/
down delay times are set via the Windows-based control
software that is included with the switcher.

 —  Press this button to turn the

projector’s “mute” function on or off (to turn off/on the
displayed image) once the Mute button has been
programmed for use with the projector.

 — For the System 5cr Plus, this button can be

programmed to switch the mode of the projector between
computer-video (RGB), S-video, and composite video.
For the System 7SC, this button can be programmed to
execute any RS-232 or IR command.

 — Turn this knob to adjust the

audio volume.  For the System 7SC this affects the Variable
(preamp) audio output, not the fixed output.  There is no
physical limit to this knob’s rotation.  The LED blinks when the
knob has reached its functional minimum or maximum limit.

 — This allows for IR control of the

switcher.  Like the IR signal pickup device on the switcher, this
receives commands from the IR 401 or IR 701 remote control and
sends them to the switcher.   Infrared signals from other devices
are not passed on through the switcher.  The IR remote must be
within 50 feet (15.2 meters) of and pointed directly at this device
for best results.

 — Room buttons control the

switcher’s Relay ports, which control “room” functions–items
such as room lighting, window coverings, and display screens–
via momentary or latching contact.  The Room 1 button can be
used for both the System 5cr Plus and the System 7SC, the
Room 2 button is used only with the System 7SC.

These contacts may be used to control any equipment as long as
the contact specifications of a total of 24 volts at 1 ampere are
not exceeded.  The Room buttons light while the room functions
are active (on).

Refer to the System 5cr Plus User’s Manual and the System 7SC
User’s Manual for information on the room function/Relay
ports).

 — These buttons correspond

to the input selection buttons on the front of the switcher.  See
page B-13 in this manual for an example of how the SCP 250’s
input selections buttons are assigned depending on the model of
switcher the SCP is connected to.
