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.
Introduction, cont’d Application Diagram The following diagram provides an example of how an SW DVI A Series switcher may be connected. PCs with DVI Output and Audio RS-232 Control TO TE MO RE TS PU IN UT TP OU - SW / AU 3 UT 2 TP 1 OU 1 4 2 TS PU IN 2 Chapter Two R WE PO X V 12 A MA 0.
Installation Installation Overview To install and set up the SW2/SW4 switcher, Rack mounting For optional rack mounting, do not install the rubber feet. Mount the switcher on any of the following rack shelves: 1 Mount the switcher on a rack shelf or furniture, if desired. • 2 Connect input source(s) to one or more SW2/SW4 video input connectors. RSB 123 1U, 3.5" Deep VersaTools® Basic Rack Shelf (part #60-604-20) • 3 Connect an output device to the SW2/SW4 output connector. RSF 123 1U, 3.
HalfRackVersaToolsStandardShelf Installation, cont’d Mounting on a standard or VersaTools rack shelf 1. If feet were previously attached to the bottom of the SW2/SW4, remove them. Mount the SW DVI A Series switcher on the rack shelf, using two 4-40 x 3/16" screws in opposite (diagonal) corners to secure the unit to the shelf (see the figures below HalfRackVersaToolsShelf and on the next page). 2. Install blank panel(s) or other unit(s) on the rack shelf as desired. 3. Install the shelf in the rack. 4.
Installation, cont’d Furniture mounting To mount the SW DVI A switcher under a desk, table, or podium, use the optional VersaTools MBU 123 Mini Under-Desk Mounting Kit (part #70-212-01), as follows: 1. If rubber feet were previously attached to the bottom of the unit, remove them. 2. Remove the two screws from one side of the SW2/SW4. Retain the screws for possible later reassembly. 3. Attach one bracket to the side of the unit, using the provided machine screws.

Installation, cont’d DVI-I Video Connectors Wiring the Power Connector If using a different external power supply from the one provided with the SW2/SW4, you may need to wire the connector for it. The DVI-I video input and output connectors have the following pin configuration: To wire the power connector, 1. Cut the DC output cord to the length needed. 2. Strip the jacket to expose 3/16" (5 mm) of the conductors.
Installation, cont’d 1. 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. NO GROUND HERE Tip Ring Sleeves Tip Ring b. Connect the orange wire to the second pin, which plugs into the Rx (receive) port. R R Sleeves Tip a. Connect the red wire to the first pin on the left, which plugs into the Tx (transmit) port. L L Tip NO GROUND HERE c.
Installation, cont’d To enable autoswitching, 1. Cut a small piece of wire to use as a jumper. 2. Insert the ends of the wire into pin holes 4 and 5 of the provided 5-pole captive screw plug, connecting pins 4 and 5 together. (See the figure at right.) 3. Use an Extron Tweeker or other small screwdriver to tighten the plug’s two screws above pin slots 4 and 5, so that the jumper wire ends remain securely in place. 4. Insert the plug into the 5-pole captive screw connector on the SW2/SW4 rear panel.
Operation Front Panel Features Operations Powering on the switcher AUTO SWITCH IR 1 INPUT EQ 2 HIGH ACTIVE LOW 1 2 ON 1 2 To power on the SW2/SW4, SIGNAL PRESENCE 1 2 1. Connect all input and output devices to the switcher’s rear panel connectors. (See chapter 2, “Installation,” for information on the rear panel connections.) 2. Power on the display. 3. Plug the power supply into the orange 2-pole captive screw power connector on the rear panel.
Operation, cont’d Using the IR 102 remote control The hand-held IR 102 Remote Control 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 Active LED.
Operation, cont’d Setting equalization for input sources High and low EQ levels for each input can be selected via the Input EQ DIP switches on the front panel. Setting these switches to High (up) compensates for a degraded/poor quality signal, reducing the need for additional signal conditioning equipment. If the input signal is strong, set the switches to Low (down). Resetting 2. Download link for SW DVI A firmware 3.
Operation, cont’d Loading the firmware to the switcher To load a new version of firmware to your SW2/SW4, use the Firmware Loader software. Your computer’s serial port must be connected to the first three pins on the switcher’s Remote/Auto-SW serial port. See chapter 2, “Installation,” for information on connecting to the serial port. 1. If you have not already done so, download the Firmware Loader installer executable file to your computer (see “Downloading the firmware,” earlier in this chapter). 2.
Operation, cont’d 9. On the Choose Firmware File window, double-click on the new firmware file to open it. The Choose Firmware File window closes, and the path to the selected firmware file is displayed in the “Select a firmware file” field on the firmware file selection screen. SW DVI A Series 4 Chapter Four 10. Click the Upload button. A status bar, which shows the progress of the upload, appears in the Firmware Loader window. The firmware upload to the switcher may take several minutes.
SIS Configuration and Control The SW2/SW4 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. See “Wiring the Remote/Autoswitching Connector” in chapter 2, “Installation,” for information on connecting to this port. Host-to-Switcher Communications SIS commands consist of one or more characters per field.
