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).
The MSW 4V rs switches between a maximum of four NTSC, PAL, or SECAM composite
video inputs on female BNC connectors and produces two identical video outputs
on female BNC connectors (see figure 1 on page 2). The video output is a buffered,
composite signal.
The MSW 4SV rs switches four S-video (luminance [Y] and chrominance [C]) inputs on
4-pin mini DIN connectors. The selected S-video input is split, buffered, and output on two
connectors (see figure 2 on page 2):
• One S-video output on a 4-pin mini DIN connector
• One composite video output on a female BNC connector
These mini video switchers can be operated from the front panel or via a contact closure
device connected to the rear panel, such as an Extron CCR 204 Four-Button Contact
Closure Remote or an IR 102 Remote Control Kit. The MSW Series include RS-232
communication, allowing control via the Extron Simple Instruction Set (SIS
™
) or the
Universal Switcher Control Program software.
They also feature a front panel selectable auto switch mode that automatically switches to
the highest numbered input that has an active sync pulse present.
