User Mode
The User Mode screen,
shown here, includes
the most frequently
used controls: input
selection, projector and
room controls, variable
output volume control,
audio/video
breakaway, freeze, and
executive mode
toggling.
Special features
Freeze — Activating Freeze causes the output image to be still (frozen). This
applies only to scaled outputs (non-RGB inputs).
Disable Front Panel — Enabling this feature locks the switcher’s entire front panel
so no changes can be made at the switcher. It does not affect the SCP control
pads. Input selection and display/projector control can be performed from
the IR 701 or via RS-232; adjustments can be done only through RS-232
control when Disable Front Panel is on.
Disable Image Controls — This is feature is identical to Executive Mode, which is
enabled by pressing the Color and Detail buttons at the same time. Disable
Image Controls locks the picture adjustment and centering controls, but not
the volume, input selection, and display controls.
I/O Configuration
The I/O Configuration
screen, shown at left,
allows you to select
video input formats,
scaler and sync output
options, and RGB
delay (Triple-Action
switching delay time)
settings. These
settings are described
in “Menus,
Configuration, and
Adjustments” in
chapter three.
