System 7SC • Operation and Configuration 3-2
Control features
1 Display buttons: Display Power, Display Mute, Mode — Each of these three
buttons can be configured/programmed to perform or send either an
infrared (IR) command or an RS-232 command. Display Power and Display
Mute each have two memory blocks that can store 256 bytes of information
apiece.
The settings of the display buttons are customized for each projector. These
buttons function only after they have been programmed, either by “learning”
IR commands or by loading projector commands (drivers) from the Extron
IR library. When a display button is pressed or activated by RS-232, one of the
following messages is displayed on the LCD screen:
Operation and Configuration
System 7SC can be set up and operated by using:
• The front panel controls.
• A computer, a touch screen panel, or any other device that can send and receive
the serial communications through the RS-232 port. Extron’s Simple
Instruction Set™ (SIS™) is a set of simple keystroke commands that can be
used with any such devices, and Extron’s control software for Windows
provides a graphical interface for controlling the switcher from a computer.
• A contact closure device.
• Extron control pads, such as the SCP 250, SCP 200, or SCP/AAP A.
• An optional IR 701 remote control, which can perform the front panel functions.
Some settings can be adjusted only through a host computer. For details on serial
communications control via the RS-232 port, see chapter 4, “Serial Communication”.

When the System 7 powers up, all of the front panel LEDs light while the
control buttons and then the input selection buttons light briefly in sequence,
then the LEDs turn off.
Each of the front panel buttons can have an RS-232 command and/or an
IR command associated with it. If the button is set up via the Windows-based
control program, pressing an input selection button could select that input and
have the System 7 send an RS-232 command and/or an IR command.
