SW DVI Plus Series • Introduction 2
Features
• Auto-input switching — The SW DVI Plus Series can be congured to automatically
switch to the active input when the switcher detects a signal. If multiple input signals are
present, the switcher switches to the highest numbered active input.
• Signal detection LEDs — Each input is represented by an LED on the front panel. Each
LED lights if a signal is present for its input.
• Independent input equalization — High or low equalization levels for each input can
be selected via the Input EQ DIP switches on the front panel. This reduces the need for
additional signal conditioning equipment to compensate for a degraded or poor quality
signal.
• EDID Minder — EDID (Extended Display Identication Data) consists of the resolution,
refresh rate, and pixel clock information of a display device. The EDID Minder manages
this information between the digital output device and all the input sources. By
maintaining continuous EDID communication with all input sources, the EDID Minder
ensures that all DVI sources power up properly and maintain their video outputs,
whether or not an active signal is displayed.
Either of the following EDID modes can be selected by SIS commands:
• Automatic, in which the SW DVI Plus reads the EDID data when a display is
connected and stores the data in memory (default mode)
• User-assigned, in which you can assign one of 15 factory-provided les of EDID
information to each input. The EDID does not change if a different display device is
connected. This mode is useful for trouble-shooting purposes.
Each time power is applied to the output device or the display is replaced, the SW DVI
Plus either reads the EDID information from the display or reloads the user-assigned
EDID information. It then writes the information to non-volatile memory on the inputs.
The input devices can read this information as they reboot (see “EDID Modes” in the
“Operation” section for more information).
• Power supply — An external 12 VDC power supply with a 2-pole captive screw
connector accepts 100 to 240 VAC.
• Rack and furniture mounting — The SW DVI Plus Series can be mounted on a rack
shelf or under a desk or podium with an optional mounting kit.
• RS-232 control — The switcher can be controlled via SIS commands issued through an
RS-232 computer interface.
• IR remote control (optional) — The hand-held IR 102 Remote Control can control the
SW DVI Plus via infrared signals that it sends to the switcher from a distance of up to
30 feet (9 m).
• Front panel security lockout (executive mode) — To prevent unauthorized access
to the switchers, front panel lock mode can be enabled via the front panel or SIS
commands. When the switcher is in lock mode, all front panel controls are disabled
(RS-232 and IR control remain available).
• Universal Switcher Control Program — The Windows
®
-based Extron Universal
Switcher Control Program, which communicates with the switcher via the RS-232 port
(non-audio SW2 and SW4 models) or the Remote/Auto-SW port (all other models),
provides an alternative way to congure and operate the SW DVI Plus switcher. The
program is compatible with Windows 2000, Windows XP, Windows 7, or higher
versions.
