Introduction This section gives an overview of the SW HDMI LC switchers. Topics covered include: zz About this Guide zz About the SW HDMI LC Switchers zz Features zz Application Diagram About this Guide This manual describes the Extron SW HDMI LC switchers and discusses how to install, configure, and operate them. In this manual, the term “SW HDMI LC” refers to both the SW2 HDMI LC and the SW4 HDMI LC switchers. “Switcher” and “SW HDMI LC” are used interchangeably to refer to any single unit.
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 (RS-232 and IR control remain available). Power supply — An included external 12 VDC, 1 A power supply with a 2-pin captive screw connector accepts 100 to 240 VAC.
Installation This section describes the installation and setup of the SW HDMI LC switchers, including: zz Installation Overview zz Rear Panel Features zz Wiring the Power Connector (Optional) zz HDMI Video Connectors Pin Assignments zz Wiring for RS-232 Control zz Enabling Auto-input Switching Installation Overview To install and set up the SW HDMI LC switcher: 1 Mount the switcher on a rack shelf or furniture, if desired. See “Mounting the SW HDMI LC” in the “Reference Information” section.

Wiring the Power Connector (Optional) A 12 VDC, 1 A desktop power supply with a 2-pin captive screw connector attached is provided with the SW HDMI LC. If you are using a different external power supply from the provided one, you may need to wire the captive screw connector for your power supply. CAUTIONS: The power supply must not be permanently fixed to the building structure or similar structures. The power supply must not be located within environmental air handling spaces or the wall cavity.
5. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector. The figure below shows how to wire the connector. 7/8” (22 mm) Heat Shrink 1/8” (3 mm) 3/16” (5 mm) Max. Tie Wrap Captive Screw Connector Figure 4. Power Connector Wiring HDMI Video Connector Pin Assignments The pin assignments for the video connectors are shown in the table below. NOTE: Appropriate HDMI to DVI cables or adapters are required for DVI signal input and output.
Wiring for RS-232 Control The 5-pin, 3.5 mm Remote/Auto-SW captive screw connector is used for optional RS-232 communication, such as firmware updates, and to enable auto-input switching between inputs connected to the switcher. Use a female 9-pin, D to bare wire RS-232 cable or a universal control cable (UC 50', UC 100', or UC 200') to connect your computer or control system to the RS-232/Auto-SW connector.
Enabling Auto-input Switching You can set up the SW HDMI LC to automatically select the active, connected input based on detection of an active video signal. If two or more inputs are active, the input with the highest number is selected (for example, input 4 on an SW4 HDMI LC switcher). When auto-input switching is in effect, the green Auto Switch LED on the front panel lights and the front panel input selection buttons are disabled. To enable auto-input switching, 1.
Operation This section describes the operation of the SW HDMI LC switchers, including: zz Front Panel Features zz Operations Front Panel Features 1 2 AUTO SWITCH IR 3 1 2 SIGNAL ACTIVE 1 2 SW2 HDMI LC HDMI SWITCHER 4 Figure 8.

SW4 HDMI LC Front Panel a Auto Switch LED — This LED lights when auto-input switching is in effect.
c Input Selection buttons and LEDs — Press these buttons to select inputs 1 and 2 or 1 through 4, depending on your model. The LED at the right of each button lights when the corresponding input is selected. (These buttons are disabled if autoinput switching is in effect; however, the LEDs continue to light to indicate the input selection.
Using the Optional IR 102 Remote Control The optional hand-held IR 102 Remote Control (part #70-224-10) lets you remotely perform functions that are also available through the front panel buttons and SIS commands. The IR receiver port on the front panel is located to the right of the Auto Switch LED.
Enabling Front Panel Lockout (Executive Mode) Executive mode disables all front panel controls, locking out the user from those functions. Putting the switcher in this mode enhances security by protecting against inappropriate or accidental changes to settings. When the switcher is in executive mode, RS-232 and IR control remain available. To lock or unlock the front panel: 1. Press and hold Input buttons 1 and 2 simultaneously. 2.
Remote Communication and Control This section describes remote control operation of the SW HDMI LC switchers, including: zz Using Simple Instruction Set (SIS) Commands zz Updating Firmware Using Firmware Loader Using Simple Instruction Set (SIS) Commands The SW HDMI LC can be remotely set up and controlled via a host computer or other device (such as a control system), attached to the rear panel Remote/Auto-SW port, using the Extron Simple Instruction Set (SIS) commands.
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.
