1-5CrossPoint Plus Matrix Switchers • Introduction
Operational flexibility — Operations such as input/output selection, setting of
presets, and adjustment of audio levels can be performed on the front panel
or over the RS-232/RS-422 link. The RS-232/RS-422 link allows remote
control via a PC, RS-232 capable PDA, or control system.
• QuickSwitch Front Panel Controller (QS-FPC™) — The CrossPoint Plus
series QS-FPC feature supports touch-of-a-button input and output selection,
preset creation and selection, and audio gain and attenuation control.
• Windows-based control program — Extron’s Windows-based control
program provides a versatile range of operational options with its graphical
interface and drag-and-drop/point-and-click operation. The Windows-based
control program also has an emulation mode that lets you create a switcher
configuration file at the home office and then download it for use by the
switcher on site.
• Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s
SIS for easy programming and operation.
Audio gain/attenuation — Users can set the input level of audio gain or
attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front
panel. Individual input audio levels can be adjusted so there are no
noticeable volume differences between sources (figure 1-3).
