Introduction This guide describes the function, installation and operation of the Extron MSW 4V rs and MSW 4SV rs mini video switchers. Unless otherwise stated, the terms “MSW” and “switcher” refer to both models. About the MSW 4V rs and MSW 4SV rs Switchers The Extron MSW 4V rs and MSW 4SV rs are four-input, two parallel output, mini video switchers (MSWs).
Auto switching — when enabled, automatically selects the highest numbered input with video sync present Vertical interval switching — ensures glitch-free transitions Compact size — 1U, quarter rack width metal enclosure External power supply — the MSW 4V rs and MSW 4SV rs units are powered by a 12 VDC, 1.
Installation Overview This section provides brief instructions for installing and operating either the MSW 4V rs or the MSW 4SV rs switcher. Users are advised to follow the links to obtain more information, elsewhere in this guide, about each step. Mount the switcher in a suitable location. Connect the composite and S-video (MSW 4SV rs only) inputs to video sources. Connect the composite and S-video (MSW 4SV rs only) outputs to video displays. Connect the power supply (provided).

b RS-232 connector — Connect a cable with a 3.5 mm, 5-pole captive screw connector to this port for bidirectional RS-232 communication. Wire the connectors as shown below. NOTE: The Tx pin on the switcher connects to the Rx connector on the PC; the Rx pin on the switcher connects to the Tx connector on the PC. Rear Panel RS-232 Port Tx Rx Green NOTE: Connect a ground wire between the switcher and the computer or control system.
f Composite video inputs 1 through 4 (MSW 4V rs only) — For each input, connect a composite video source to one of these BNC connectors. g Power connector — Plug the external 12 VDC power supply into this 2-pole, 3.5 mm captive screw connector. The power supply is included with the unit. If power is disconnected from the MSW, the unit retains mode and input settings. CAUTIONS: • Always use a power supply supplied by or specified by Extron.
4. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector. 5. Before connecting the power cord, verify the polarity by plugging it into the power supply with no load and checking the output with a voltmeter. WARNING The two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.
Mode Selection The default method for changing channels is Normal mode (using front panel buttons). To activate auto switch mode: 1. Press and hold the Mode (Input 1) and Auto (Input 3) buttons simultaneously. 2. Release the Mode and Auto buttons simultaneously. The Auto Switch LED turns on, indicating that auto switch is enabled. AUTO SWITCH MODE NORMAL 1 AUTO 2 4 3 A/V SWITCHER Figure 7. Turning on Auto Switch Mode To turn auto switch mode off (Normal mode): 1.
Control Software Universal Switcher Control Program The Windows®-based Extron Universal Switcher Control Program provides an alternative to configuring and operating the switcher through the front panel or SIS commands. The program is compatible with Windows 2000 or later versions of the Windows operating system. Installing the Software The control program can be downloaded from the Extron Website and is on the Extron Software Products DVD. Install the software from the DVD as follows: 1.
Using the Software 1. To run the software, double-click the Universal Switcher Control Program icon on your PC desktop. 2. In the Communication Setup window (see figure 11), select the comm port that is connected to the RS-232 port on the MSW. Click OK. Figure 11. Communication Setup Window 3. The Universal Switcher Control Program window displays the selected input and switching mode (Front Panel or Auto Switch). Figure 12.
4. Select and click the desired input button. Symbols for the state of each LED are shown below: Indicates that the input signal is not present and not selected Indicates that the input signal is selected Supresses the video image When unlit (as shown), the switcher is in normal mode; when lit (green), the switcher is in auto switch mode 5. Click on the Auto Switch tab in the top right corner to reveal the Auto Switch status box. The Auto Switch radio buttons indicate which mode is currently selected. 6.
Downloading and Installing the Firmware Loader Extron recommends using the Firmware Loader software to update the firmware on the MSW 4V rs and MSW 4SV rs. If you do not already have the Firmware Loader software installed on your computer, download it as follows: 1. Go to www.extron.com/download. 2. On the Download Center screen, click Software in the left sidebar menu. 3. On the next Download Center screen, locate and click the Download link for the latest version of Firmware Loader. Figure 13.
3. The Add Device window appears. On the Add Device window, select the appropriate device and connection method. Figure 15. Add Device Window 4. From the remaining drop-down menus, select the appropriate port configuration parameters (obtained from your system administrator). The defaults are 9600 baud rate, no parity, 8 data bits, and one stop bit. 5. Click on the Connect button. The name of the selected device should appear in green text with a check mark next to it. 6.
7. If you will be uploading firmware to multiple MSW switchers, do the following: a. Click Add Next. Your first device is added to the Devices field in Firmware Loader window, and the Add Device window remains open. b. Enter the connection information for the device and click the Connect button. c. Select the appropriate firmware for the device by using the Browse button. d. Repeat steps 7a through 7c until all desired devices have been added to the Firmware Loader window. 8.

SIS Commands This section provides information about the Extron Simple Instruction Set (SIS) commands that are used to configure the switchers: • Introduction to SIS • Symbols Used in this Guide • Error messages • Command and Response table for SIS commands Introduction to SIS The MSW 4V rs and MSW 4SV rs accept SIS commands from a control device connected to the RS-232 5-pole, rear panel captive screw connector (see RS-232 connector).
Symbols Used in this Guide When programming in the field, certain characters are most conveniently represented by their hexadecimal rather than their ASCII values. The table below shows the hexadecimal equivalent of each ASCII character: ASCII to HEX Conversion Table Space . Figure 18.
Command and Response Table for SIS Commands Command ASCII Command (host to unit) Response (unit to host) Additional Description X! ! InX!] Selects input (X! 1 to 4) Request status of all inputs 0S Sig•X@•X@•X@•X@] Each X@ response is the signal status of an input, from input 1 to 4. X@ = 0 (no signal) or 1 (signal detected). Example: 0S Sig•1•0•0•1] Input 1 = signal present; input 2 = no signal present; input 3 = no signal present; input 4 = signal present.
