Extron electronic System 7SC manual Controlling the switcher and an A/V system

Page 9

The System 7SC scales composite video, S-video, and component video up to computer-video (RGBHV/RGBS/RGsB), which can be output to two display devices via individually buffered BNC and 15-pin HD ports. The System 7SC offers one fixed level (preamp) stereo audio output and one variable level stereo audio output.

Rear panel ports allow connection of remote control keypads, the IR Emitter and/ or the optional IR Broadcaster, an optional display power sensor, hardwired projector control, and an RS-232 controller. The System 7SC also has a power port to provide power for accessories such as SCP control pads.

Controlling the switcher and an A/V system

The System 7SC can be controlled using one or more of these items:

•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.

•The optional IR 701 remote control, which can perform all of the front panel functions.

For the System 7SC switcher to control a projector, it must be programmed. The switcher can be programmed by having it learn projector IR commands, or Extron’s IR/RS-232 library of commands can be loaded into the switcher’s memory. The IR/RS-232 library and the latest control software are available on the Extron Web site at http://www.extron.com.

The System 7SC learns new projector control commands from infrared (IR) signals it receives via its front panel IR port or from commands input via an RS-232 device. These commands are stored in the switcher’s memory and assigned to the front panel control (Display Power, Display Mute, Mode, Room 1, Room 2) and input buttons. When a button is pressed, the switcher transmits the stored signals to the projector via the IR comm port or the projector control RS-232 port. The IR 701, optional control pads, and/or an RS-232 control system can also be used to execute these stored commands.
