Introduction
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 with
active sync pulses present.

Installation and Operation
Mounting
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 inch Deep Rack Shelf Kit
(part #60-190-20, see figure 3 on page 4)
• RSB 123 1U 3.5 inch Deep Basic Rack Shelf
• RSU 126 1U 6 inch Deep Universal Rack Shelf Kit
(part #60-190-10)
• RSB 126 1U 6 inch Deep Basic Rack Shelf (part #60-604-11)

(part #60-190-01, see figure 4 on page 4)
• RSB 129 1U 9.5 inch Deep Basic Rack Shelf
(part #60-604-02)
UL requirements
The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the MSW on a rack.
1.
Elevated operating ambient temperature — If installed in
a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than
room ambient temperature. Therefore, install the MSW in
an environment compatible with the maximum ambient
temperature (TMA) specified by Extron
(TMA = +122 °F, +50 °C).
2. Reduced air flow — Install the equipment in a rack so that
the amount of air flow required for safe operation is not
compromised.
3. Mechanical loading — Mount the equipment in the rack so
that a hazardous condition is not achieved due to uneven
mechanical loading.
4. Circuit overloading — Connect the equipment to the supply
circuit and consider the effect that circuit overloading
might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings
should be used when addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections (for example, the use of
power strips) other than direct connections to the branch
circuit.

To select an input using a contact closure device, such as an
Extron CCR 204 Contact Closure Remote Control or a locally
constructed device, momentarily short the pin for the desired
input number to logic ground (pin 5). To force one of the
inputs to be always selected, leave the short in place. The short
overrides any front panel input selections.
You can also daisy chain multiple MSWs by using the contact
connector. This allows for front panel control of all switchers
(for example, touch the input button on one MSW to switch all
MSWs). Wire pin 1 to pin 1, pin 2 to pin 2, and so on.
