Introduction This section gives an overview of the SW HDMI Series switchers. Topics include: • About this Guide • About the SW HDMI Series Switchers • Features • Application Diagrams About this Guide This guide describes the Extron SW HDMI Series switchers and discusses how to install, configure, and operate them. In this guide, the term “SW HDMI Series” refers to the SW2, SW4, SW6, and SW8 HDMI switchers. “Switcher” and “SW HDMI” are used to refer to any single unit.
• Rack and furniture mounting — The SW HDMI Series can be mounted on a rack shelf or under a desk or podium with an optional mounting kit. • Remote configuration and control — The switcher can be configured via an RS-232 or USB connection via SIS commands (see Remote Communication and Control beginning on page 21).

a Power connector — • SW2 and SW4 HDMI: Plug the provided external 12 VDC, 1 A power supply into this 2-pole, 3.5 mm captive screw connector and into an AC power outlet. ATTENTION: Do not connect power to the switcher until you have read the CAUTION and ATTENTION notices on the next page. • b Input connectors — Connect HDMI video input sources to these female Type A single-link HDMI connectors. Data rates of up to 6.75 Gbps are supported.
f Tally Out port — (Optional) Plug one of the provided 5-pole captive screw connectors into this 5-pole captive screw port to indicate which input has been selected. On the SW6 and SW8 HDMI, plug connectors into either or both parts of the dual Tally Out port. Connect an indicator device such as an LED to the attached connector to identify the currently selected input when the front panel buttons are not visible (see Wiring the Tally Out Port to Indicate the Input Selection on page 12).
5. Use the supplied tie wrap to strap the power cord to the extended tail of the connector. Heat Shrink 7/8" (22 mm) 1/8" (3 mm) Captive Screw Connector 3/16" (5 mm) Max. Figure 7. Tie Wrap Wiring the Power Connector Wiring for RS-232 Control Use a female 9-pin D to bare wire RS-232 cable or a universal control cable (UC50' or UC100') to connect your computer or control system to the RS-232 pins of the Remote connector. 1.
Connecting to the USB Port The mini B USB port is located on the SW HDMI front panel. It can be used to configure the switcher via SIS commands. 1. Connect a USB A to mini B cable between the USB Config port on the switcher front panel and the USB port on your computer.

• Select Yes, now and every time I connect a device if you want the computer to automatically connect to Windows Update to search the web every time the switcher is connected to this USB port. • Select No, not this time if you do not want the computer to connect to Windows Update to search the web at this time (for example, if the driver is already on your computer). 3. Click Next.
3. Use a small screwdriver to tighten the two screws above pin slots 4 and 5 of the plug so that the jumper wire ends remain securely in place (see figure 12). 4. Insert the plug into the 5-pole Remote captive screw connector on the rear panel. Figure 12 shows an SW4 HDMI with a jumper connecting pins 4 and 5 to enable auto-input switching.
Wiring the Tally Out Port to Indicate the Input Selection To identify the currently selected input when the front panel buttons are not visible, you can connect an indicator device such as an LED to an input pin and the +V pin of the Tally Out port. When the input you are using is selected, the corresponding tally out pin shorts to ground, which activates the connected indicator. To connect an indicator to the Tally Out port: 1. Plug one of the provided 5-pole connectors into the Tally Out port.

Operations Powering on the Switcher To power on the SW HDMI: 1. Connect all input and output devices to the rear panel connectors on the switcher (see Rear Panel Features on page 5 for the rear panel connections). 2. Power on the display. 3. Power on the SW HDMI: • SW2 and SW4 HDMI: Plug the power supply into the 2-pole captive screw power connector on the switcher rear panel. • SW6 and SW8 HDMI: Plug the provided IEC cord into the rear panel IEC connector and an AC outlet.
Other ways to select an input include using SIS commands (see the Input Selection command on page 24) and optional IR remote control (see “Using the Optional IR 102 Remote Control”). 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.
Locking IR remote access The SW HDMI can be set to lock out users from using the IR 102 Remote Control to control the switcher. Remote access can be enabled and disabled via SIS commands (see the Front Panel IR Receiver Enable and Disable commands on page 25). When remote access is disabled, all switcher controls remain available through the SW HDMI front panel.
User-assigned EDID mode In this mode, you can select an EDID file that is stored on the switcher. The selected EDID is stored in memory for the inputs and is not overwritten. The switcher does not 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.
EDID table EDIDs listed in this table are arranged according to video format: DVI or HDMI. Within each video format grouping, the EDIDs are listed by rate type: PC or HDTV. Within each rate type grouping, the EDIDs are listed in order of resolution.
Footnotes for the EDID table The following footnotes apply to the EDID table on the previous page: Rate type 1 • PC: These are primarily VESA standard computer rates, based on the most commonly used native resolutions. They are designed to be used with computer sources. • HDTV: These are video rates standardized by SMPTE and CEA. They are designed to be used with video and computer sources. Video format 2 DVI: These are 128-byte EDID files, which specify a DVI sink.
Remote Communication and Control This section describes remote operation of the SW HDMI switchers. Topics include: • Using Simple Instruction Set (SIS) Commands • Updating Firmware Using Firmware Loader Using Simple Instruction Set (SIS) Commands The SW HDMI can be remotely set up and controlled via Extron SIS commands that are issued from a host computer or other device, such as a control system.
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.

Updating Firmware Using Firmware Loader Updates to the SW HDMI Series firmware are made available periodically via the Extron website. You can find out what version of firmware is currently loaded on your switcher by entering the SIS Q command via the RS-232 or USB interface (see the Query Firmware Version command on the previous page). Downloading and Installing Firmware Loader Extron recommends using the Firmware Loader software to update the firmware on the SW HDMI.

ATTENTION: Valid firmware files must have the file extension S19. A file with any other extension is not a firmware upgrade for this product and could cause the switcher to stop functioning. NOTE: The original factory-installed firmware is permanently available on the SW HDMI. If the attempted firmware upload fails for any reason, the switcher reverts to the factory version. On the Add Device window, the path to the new firmware file is displayed in the Path field. Figure 24.
