Introduction
About this Manual
This manual describes the Extron SW2 DVI A and SW4 DVI A
switchers, and discusses how to install, congure, and operate
them. The terms “SW2/SW4” and “switcher” are used
interchangeably throughout this manual to refer to either model.
About the SW DVI A Series
The Extron SW DVI A Series switchers are two and four input,
one output, single link Digital Visual Interface (DVI) audio and
video switchers that select among multiple DVI-D input signals
for one compatible display device. They can accept and route
computer resolutions up to 1920x1200 or 1080p @ 60 Hz, and
have a pixel bandwidth of up to 165 MHz. All DDC (Display
Data Channel) and communication signals are switched from
the selected source to the output display.
The SW DVI A switchers can be controlled from the front
panel, through the RS-232 interface, or using the IR 102 Remote
Control. You can select video/audio inputs by pressing the
front panel buttons, by enabling autoswitching using a jumper
wire, by entering Simple Instruction Set (SIS™) commands via
RS-232, or by pressing buttons on the IR 102.
N
The SW DVI A Series switchers are not compatible with
HDCP signals.
Features
Autoswitching — The SW DVI A Series can be congured
to automatically switch to the active input when the
SW2/SW4 detects a signal, thus providing hands-free
switching. If multiple input signals are present, the
switcher switches to the highest numbered active input.
Audio — The SW DVI A Series supports balanced and
unbalanced stereo audio signals.
Enclosure — The SW DVI A Series has a compact 1U high,
½-rack wide, 3.5 inches deep VersaTools® metal enclosure
that can be easily placed or mounted in a variety of
locations.
Signal detection LEDs — Each input is represented by an LED
on the front panel. Each LED lights if a signal is present
for its input.
Independent input equalization — High and low equalization
levels for each input can be selected via the Input EQ
DIP switches on the front panel. This reduces the
need for additional signal conditioning equipment by
compensating for a degraded/poor quality signal.
EDID Minder — To enhance and simplify integration, the
switchers feature the EDID Minder, which manages
the EDID (Extended Display Identication Data)
information between the digital output device and all
the input sources. (EDID is the communications protocol
or instruction set that identies the display device to
computers using the DDC transmission standard.)
Each time power is applied or recycled to the output
device or the display is replaced, the SW DVI reads
the EDID information from the display and writes it to
non-volatile memory on each switcher input. The input
devices can then read this information after they are
rebooted.
By maintaining continuous EDID communication with
all input sources, the EDID Minder ensures that all DVI
sources power up properly and maintain their video
outputs, whether or not they are actively connected to the
digital display device through the SW2/SW4 output.
Power supply — An external 12 VDC power supply with a
two-pin captive screw connector accepts 100 to 240 VAC.
Rack and furniture mounting — The SW DVI A Series can be
mounted on a rack shelf or under a desk or podium with
an optional mounting kit.
RS-232 control — You can control the switcher by issuing SIS
commands via an RS-232 connection.
IR remote control — The hand-held IR 102 Remote Control can
control the SW2/SW4 via infrared signals that it sends to
the switcher from a distance of up to 30 feet.
Front panel security lockout (executive mode) — To prevent
unauthorized access to the switchers, executive mode can
be enabled via the front panel or SIS commands. When
the switcher is in executive mode, all front panel controls
are disabled.

UL rack mounting guidelines
The following Underwriters Laboratories (UL) guidelines
pertain to the safe installation of the equipment in a rack.
1. Elevated operating ambient temperature — If the
equipment is 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 equipment in an
environment compatible with the maximum ambient
temperature (Tma = +113 °F, +45 °C) specied by Extron.
2. Reduced air flow — Install the equipment in a rack so that
the amount of air ow required for safe operation of the
equipment 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 other than direct
connections to the branch circuit (e.g., use of power strips).

The gure below shows how to wire the connector.
Exposing more than 3/16” (5 mm) of the copper
wires could allow the stripped wires to touch each
other, causing a short circuit. This could result in
the external DC power supply overheating and/or
burning.
Stripping the wires to expose less than the
recommended amount may cause them to slide out
of the connector too easily, even if they are tightly

Using the IR 102 remote control
The hand-held IR 102 Remote Control lets you remotely perform
functions that are also available through the front panel buttons
and SIS commands.
The IR receiver port on the front panel is located to the right
of the Auto Switch Active LED. It receives signals from the
remote control if they are sent from within a 40 degree arc to the
right or left of direct line of sight between the remote and the
switcher’s receiver, and from no more than 30 feet (9 m) away.
(See the illustration below.)

Locking IR remote access
The SW2/SW4 can be set to lock out users from using the IR 102
Remote Control to control the switcher. Remote access can be
enabled and disabled via SIS commands (see chapter 4, “SIS
Conguration and Control”). When remote access is set to off,
all switcher controls remain available through the SW2/SW4
front panel.
Enabling front panel lockout (executive mode)
Executive mode disables all front panel controls, locking out
the user from those functions. Putting the switcher in this
mode enhances security by protecting against inappropriate
or accidental changes to settings. When the SW2/SW4 is in
executive mode, RS-232 and IR control remain available.
To lock or unlock the front panel, press and hold Input buttons
1 and 2 simultaneously for 3 seconds, then release. The front

Setting equalization for input sources
High and low EQ levels for each input can be selected via
the Input EQ DIP switches on the front panel. Setting these
switches to High (up) compensates for a degraded/poor quality
signal, reducing the need for additional signal conditioning
equipment.
If the input signal is strong, set the switches to Low (down).
Resetting
To reset the switcher to its factory default settings,
1. Press and hold the Input 1 button while power is being
applied to the unit.
2. Continue holding the Input 1 button until the power-up
sequence completes.

The SW2/SW4 can be remotely set up and controlled via a host
computer or other device (such as a control system), attached
to the rear panel Remote/Auto-SW port, using the Extron
Simple Instruction Set (SIS™) commands. See “Wiring the
Remote/Autoswitching Connector” in chapter 2, “Installation,”
for information on connecting to this port.
Host-to-Switcher Communications
SIS commands consist of one or more characters per eld. No
special characters are required to begin or end a command
sequence. You can enter these commands from your
computer using a communication software program such as
HyperTerminal. When the switcher determines that a command
is valid, it executes the command and sends a response to the
host device.
Most responses from the SW2/SW4 to the host computer 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 selection takes place,
the switcher responds by sending a message to the host,
indicating what selection was entered. No response is required
from the host. The following SW2/SW4-initiated message is
displayed:
(C) Copyright 2007, Extron Electronics DVI Switcher Series,
Vx.xx, 60-840-xx
The switcher sends the copyright message when it rst powers
on. Vx.xx is the rmware version number.
N
Error responses
If the switcher is unable to execute a command it receives
because the command is invalid or contains invalid parameters,
the SW2/SW4 returns an error response to the host. Error
response codes and their descriptions are as follows:
E01 – Invalid input channel number (out of range)
E06 – Invalid input selection during autoswitch
E10 – Invalid command
E13 – Invalid value (out of range)
This message is displayed only at power-up.
Using the Command/Response Table
The command/response table on the following pages lists
