Introduction About this Manual The Extron MSW 4V rs and MSW 4SV rs are four-input, two parallel output, mini video switchers (MSWs). The MSWs are members of the Extron VersaTools® line of basic distribution amplifiers, switchers, and associated video accessories. The MSW 4V rs switches among up to four NTSC, PAL, or SECAM composite video inputs on female BNC connectors, and outputs two identical buffered composite video outputs on female BNC connectors (figure 1-1).

Installation and Operation Installation The 1U high, quarter rack width, MSW 4V rs and MSW 4SV rs can be mounted on a rack shelf, under a desk, or on a tabletop. Rack mounting For optional rack mounting, mount the MSW on any of the following rack shelves: • RSF 123 1U 3.5" Versatools® Rack Shelf Kit (part #60-190-20) (figure 2-1) • RSB 123 1U 3.

Cut the DC output cord to the length needed. 2. Strip the jacket to expose 0.2” (5 mm) of the conductors for the blue captive screw plug, or 0.3” (7 mm) for the orange plug.
Installation and Operation, cont’d N Stripping the wires to expose less than the recommended amount causes them to slide out of the connector too easily, even if they are tightly pinched by the captive screws. 3. Slide the leads into the supplied captive screw plug and lock them, using an Extron Tweeker (small screwdriver). 4. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector. 5.

Serial Communication Using Simple Instruction Set (SIS) Control Host-to-switcher communications The Extron Simple Instruction Set (SIS) commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the switcher executes the command and sends a response to the host device.

Serial Communication, cont’d Windows-Based Control Program 3. The Universal Switcher Control Program (part #29-031-01), is compatible with Windows 2000 and Windows XP or later, and it provides remote control of input selection and front panel switch mode selection. The Extron Universal Switcher Control Program window (figure 3-4) displays the selected input and panel mode (Front-Panel [normal] or Auto-Switch).
Serial Communication, cont’d Updating the Firmware Extron periodically updates product firmware in conjunction with the release of new software revisions. When updating any Extron software to the latest revision level, please be sure to read the supplied release notes, or contact an Extron Application Engineer to determine if your Extron product requires a firmware update. To find the latest MSW firmware, do the following: 1. Go to www.extron.com and click the Download tab. 2.
Serial Communication, cont’d 8. A status bar, showing the progress of the upload appears in the Firmware Loader window. The firmware upload to the switcher may take several minutes. Once the status bar has progressed fully from left to right across the indicator window, the Firmware Loader utility automatically resets the switcher.
