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).
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 2
connectors (figure 1-2):
• 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 contact closure remote (Extron part
#60-797-02) or an IR 102 Remote Control Kit (part #70-224-01).
The MSW series include RS-232 communication, allowing
control via Extron’s Simple Instruction Set (SIS)
TM
or the
Universal Switcher Control Program software.
They also feature a front panel selectable autoswitch mode that
automatically switches to the highest numbered input with
active sync pulses present.
All units ship with an external 12 VDC power supply.
