Introduction

About this Manual

This manual describes the Extron SW2 DVI A and SW4 DVI A switchers, and discusses how to install, configure, and operate them. The terms “SW2/SW4” and “switcher” are used interchangeably throughout this manual to refer to either model.

About the SW DVI A Series

The Extron SW DVI A Series switchers are two and four input, one output, single link Digital Visual Interface (DVI) audio and video switchers that select among multiple DVI-D input signals for one compatible display device. They can accept and route computer resolutions up to 1920x1200 or 1080p @ 60 Hz, and have a pixel bandwidth of up to 165 MHz. All DDC (Display Data Channel) and communication signals are switched from the selected source to the output display.

The SW DVI A switchers can be controlled from the front panel, through the RS-232 interface, or using the IR 102 Remote Control. You can select video/audio inputs by pressing the front panel buttons, by enabling autoswitching using a jumper wire, by entering Simple Instruction Set (SIS™) commands via RS-232, or by pressing buttons on the IR 102.

NThe SW DVI A Series switchers are not compatible with HDCP signals.

Features

Autoswitching — The SW DVI A Series can be configured to automatically switch to the active input when the SW2/SW4 detects a signal, thus providing hands-free switching. If multiple input signals are present, the switcher switches to the highest numbered active input.

Audio — The SW DVI A Series supports balanced and unbalanced stereo audio signals.

Enclosure — The SW DVI A Series has a compact 1U high, ½-rack wide, 3.5 inches deep VersaTools® metal enclosure that can be easily placed or mounted in a variety of locations.

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 and 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 by compensating for a degraded/poor quality signal.

EDID Minder — To enhance and simplify integration, the switchers feature the EDID Minder, which manages the EDID (Extended Display Identification Data) information between the digital output device and all the input sources. (EDID is the communications protocol or instruction set that identifies the display device to computers using the DDC transmission standard.)

Each time power is applied or recycled to the output device or the display is replaced, the SW DVI reads the EDID information from the display and writes it to non-volatile memory on each switcher input. The input devices can then read this information after they are rebooted.

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 they are actively connected to the digital display device through the SW2/SW4 output.

Power supply — An external 12 VDC power supply with a two-pin captive screw connector accepts 100 to 240 VAC.

Rack and furniture mounting — The SW DVI A Series can be mounted on a rack shelf or under a desk or podium with an optional mounting kit.

RS-232 control — You can control the switcher by issuing SIS commands via an RS-232 connection.

IR remote control — The hand-held IR 102 Remote Control can control the SW2/SW4 via infrared signals that it sends to the switcher from a distance of up to 30 feet.

Front panel security lockout (executive mode) — To prevent unauthorized access to the switchers, executive mode can be enabled via the front panel or SIS commands. When the switcher is in executive mode, all front panel controls are disabled.
