Introduction This section gives an overview of the Extron SW DVI Plus Series switchers, describes their significant features, and provides examples of application diagrams. The following topics are covered: • About this Guide • About the SW DVI Plus Series • Features • Application Diagrams About this Guide This guide describes the SW DVI Plus Series switchers and discusses how to install, configure, and operate them.
Features • Auto-input switching — The SW DVI Plus Series can be configured 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.
Application Diagrams The following diagrams provide examples of how an SW DVI Plus Series switcher can be connected.

Installation This section gives an overview of the steps to install the SW DVI Plus switchers and detailed instructions for cabling. It also provides a description of the rear panel connectors. The following topics are covered: • Installation Overview • Rear Panel Features • Wiring the Power Connector • Wiring the Audio Connectors (SW DVI A Plus Models) • Wiring for RS-232 Control • Enabling Auto-input Switching Installation Overview To install and set up the SW DVI Plus switcher: 1.

c RS-232 connector (SW2 and SW4 DVI Plus non-audio models only) — For RS-232 control, connect your computer serial port to this 9-pin female D connector. (For more information, see “Wiring for RS-232 Control” on page 9.) d Remote and auto-input switching connector — This 5-pole, 3.5 mm captive screw connector (labeled “Remote/Auto-SW”) can be used for RS-232 communication with the switcher and to enable auto-input switching.
3. Slide the leads into the supplied 2-pole captive screw plug and secure them, using a small screwdriver. CAUTION: Do not tin the stripped power supply leads before attaching the captive screw plug to them. Tinned wires are not as secure in the captive screw connectors and can be easily pulled out. They may also break after being bent several times. 4. To verify the polarity of the power cord before connecting it, plug in the power supply with no load and check the output with a voltmeter.
Audio Output The 5-pole captive screw audio output connector is used for both balanced and unbalanced audio. When the connector is wired for unbalanced audio, the gain is unity.

a Auto Switch Active LED — This LED lights when auto-input switching is enabled. (See “Enabling Auto-input Switching” in the “Installation” section for the procedure to set up auto-input switching.) b IR receiver port — This sensor detects IR signals from the optional IR 102 remote control (see “Using the Optional IR 102 Remote Control” on page 14 for more information). c Input Selection buttons and LEDs — Press these buttons to select inputs 1 through 2, 4, 6, or 8, depending on your model.
Other ways to select an input include using SIS commands (see the Input Selection commands in the Command and Response Table for SIS Commands, “Remote Configuration and Control” section) or the optional IR remote control (see “Using the Optional IR 102 Remote Control”). Front panel input selection is disabled when auto-input switching is in effect.
Enabling Front Panel Lockout (Executive Mode) Front panel lock mode (executive mode) disables all front panel controls. Putting the switcher in this mode enhances security by protecting against inappropriate or accidental changes to settings. When the switcher is in lock mode, RS-232 and IR control remain available. To lock or unlock the front panel, press and hold Input buttons 1 and 2 simultaneously for 3 seconds, then release them.
User-assigned EDID mode In this mode, you can select an EDID file that is stored on the switcher at the factory. The selected EDID is stored at the inputs and is not overwritten; the switcher does not automatically obtain EDID information from the display. You may want to use this mode if there is a problem with automatic communication of the EDID information from the attached display, and you want to ensure that the correct information is stored on the inputs.
Resetting To reset the switcher to its factory default settings: 1. Press and hold the Input 1 button while power is being applied to the unit. 2. Continue holding the Input 1 button until the power-up sequence completes. NOTE: Resetting restores the EDID mode to automatic, with a resolution of 1024x768 @ 60 Hz. If a display is connected at the time of the reset, its EDID information is detected and stored at the inputs.
Remote Configuration and Control This section describes remote operation of the SW DVI Plus series. Topics include: • Using Simple Instruction Set (SIS) Commands • Universal Switcher Control Program • Updating Firmware Using Firmware Loader Using Simple Instruction Set (SIS) Commands The SW DVI Plus can be remotely set up and controlled via a host computer or other device (such as a control system) that is attached to the rear panel Remote/Auto-SW port.
Error Responses If the switcher is unable to execute a command it receives because the command is invalid or contains invalid parameters, the switcher returns an error response to the host.
