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.

Extron. Use of an unauthorized power supply voids
all regulatory compliance certification and may
cause damage to the supply and the end product.
Unless otherwise stated, the AC/DC adapters
are not suitable for use in air handling spaces or
in wall cavities. The installation must always be
in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 75
and the Canadian Electrical Code part 1, section 16.
The power supply shall not be permanently fixed to
building structure or similar structure.

The length of the exposed (stripped) copper wires is

important. The ideal length is 3/16 inch (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the connector and could be
pulled out.

3. Slide the leads into the supplied captive screw plug and

secure them using a small screwdriver.

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.

C

Do not tin the stripped power supply leads before

installing the captive screw connector. Tinned
wires are not as secure in the captive screw
connectors and can be easily pulled out. They may
also break after being bent several times.

W

The two power cord wires must be kept separate

while the power supply is plugged in. Remove
power before wiring.

Alternately, an Extron PS 124 Universal 12 VDC power supply



(part #60-1022-01) can power up to eight MSWs or other Extron
12 VDC devices using only one AC power connector.

SIS

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. All responses from the
switcher to the host end with a carriage return and a line feed
(CR/LF = ]), which signals the end of the response character
string. A string is one or more characters.

Switcher-initiated messages

When a local event (such as a front panel operation or error
condition) occurs, the switcher responds by sending a message
to the host. The switcher-initiated messages are listed below:

(c) Copyright 2010, Extron Electronics, MSW Series Switchers,
Vx.xx]

The switcher issues the copyright message and the input
selected message when it first powers on. Vx.xx is the firmware
version number.

Inn]
The switcher sends the Inn message whenever the selected

input is changed using the front panel buttons. “n” is the input
number.

Error responses

13

MSW 4V rs and 4SV rs • SIS

When the switcher receives a valid SIS command, it executes
the command and sends a response to the host device. If
the switcher is unable to execute the command because the
command is invalid or it contains invalid parameters, the
switcher returns an error response to the host. The error
response codes are:

E01 – Invalid input channel number (out of range)
E06 – Invalid input channel change (auto switch is active)
E10 – Invalid command
E13 – Invalid parameter

Timeout

Pauses of 10 seconds or longer between command ASCII
characters result in a timeout. The command operation is
aborted with no other indication.

RS-232 communication

Wire the RS-232 connector as shown on page 7. Connect the
MSW to a PC via the RS-232 port. Use a communication utility,
such as Telnet, to send SIS commands (see page 16) and view the
responses.
