defined buttons. IR commands may be
learned through the System 7SC’s user-
friendly IR learning capabilities, which make
it compatible with almost every type of IR-
controllable display device. For RS-232
commands, Extron’s Simple Instruction Set™
is provided for RS-232 control via Extron’s
Windows®-based control program or third-
party control.
Trigger signals to control room lighting,
screen settings, and other device controller
functions may be controlled through the
System 7SC’s room function, using internal
relays. Relays may be controlled from the
front panel, included IR 70 remote
(included), or RS-232 control.
System switcher control is provided via
front panel operation, IR 70, or RS-232. The
front panel buttons control video and audio
input selection; picture adjustments; display
functions such as power, mute, video modes;
and internal relays for room controls, such as
lowering or raising a display screen or
powering lights on or off. Picture controls
include horizontal and vertical shift, color,
tint, brightness, contrast, detail (image
sharpness), and top & bottom vertical
blanking. Variable vertical blanking
adjustments allow a user to mask noise that
occasionally appears at the top and bottom
of a processed image or to crop unneeded
portions of an image. The IR 70 duplicates
the front panel functions for normal
operation. For mobile control from any part
of the room—useful for a presenter or
meeting facilitator—the IR 70 provides
infrared remote control. All functions are also
available through RS-232.
ETC.
With a video bandwidth of 350 MHz
(-3dB), the System 7SC maintains origional
