Introduction
About this Manual
This manual describes the Extron SW2 USB, SW4 USB,
and SW4 USB Plus switchers, and discusses how to install,
congure, and operate them. The term “SW USB” is used
throughout this manual to refer to all models.
About the SW USB Series
The Extron SW2 USB, SW4 USB, and SW4 USB Plus switchers
enable USB peripheral devices (such as keyboards and mice)
to be collectively switched between multiple host PCs. In
addition, the SW USB Plus model provides host and peripheral
emulation, enabling constant communication to peripheral
devices and hosts.
A number of specialized features help to streamline system
integration, including port status indication, RS-232 passthrough, front panel security lockout, and multiple control
points.
The SW USB Series switchers also have integrated active USB
hubs, allowing multiple USB peripherals to be connected to
the switched PC inputs. Each port is can supply 5V, 500 mA
to attached devices, per USB specication. In addition, the
switchers are USB 2.0 compatible, and are compatible with all
previous USB data rate specications, including low speed
1.5 Mbps, full speed 12 Mbps, and high speed 480 Mbps.
RS-232 pass-through functionality reduces RS-232 control
port requirements by processing SIS™ (Simple Instruction Set)
commands within the SW USB while also passing them through
to other RS-232 controllable Extron audio and A/V switchers.
The SW USB Series are rack and furniture mountable, with
1U, half-rack width enclosures for simplied integration.
All models include an external universal power supply for
worldwide power compatibility.
Features
Outputs — Four female USB type A connectors act as a USB
hub, allowing simultaneous connection to multiple
peripheral devices such as mass storage devices,
keyboards, mice, and other human interface devices
(HIDs). Each output supplies the 500 mA, 5V rating
required in the USB specication.
USB 2.0 compatibility — The SW USB supports 480 Mbps high
speed communications and is backward compatible with
all prior USB versions.
Enclosure — The SW USB Series switchers have compact 1U
high, ½-rack wide, 3.0 inches deep metal enclosures that
can be easily placed or mounted in a variety of locations.
Active USB LEDs — These LEDs provide visual indication of
port status/activity for USB peripherals and all connected
and active host devices.
Host and peripheral emulation — The SW4 USB Plus model
offers increased system reliability by providing an
uninterrupted connection between host and peripheral
devices, such as a standard keyboard and/or mouse. This
means that, when a keyboard or a mouse is connected to
port 3 or 4, and the appropriate rear panel DIP switch is
set to on, the SW USB switches to the connected keyboard
or mouse instantly. See “Host emulation (SW4 USB Plus
only),” in chapter 3, “Operation”, for more information.
RS-232control and pass-through — You can control the
SW USB switcher by issuing SIS commands to it via the
RS-232 interface. In addition, these SIS commands can
be passed through the SW USB’s Pass Thru port to an
RS-232 controllable Extron A/V switcher attached to the
RS-232 Pass Thru port. (See chapter 4, “SIS Conguration
and Control”, for an explanation of the available SIS
commands.)
Contact closure control — Connecting a push-button contact
closure device to the SW USB’s Contact port, or shorting
pin 1, 2, 3, or 4 to the ground (_) pin of the Contact port,
provides an alternative method of input selection on
the SW USB. Commands issued via contact closure can
also be passed through the RS-232 Pass Thru port to
an attached RS-232 controllable Extron switcher. See
“Contact Closure Control”, in chapter 2, “Installation”, for
more information.
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 USB switchers can be
mounted on a rack shelf or under a desk or podium, with
an optional mounting kit.
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.

switches enable host emulation to a keyboard and/or mouse
connected to output ports 3 and 4. Switch 1 enables host
emulation to a mouse; switch 2 enables emulation to a keyboard.
When a keyboard or a mouse is connected to port 3 or 4, and
the appropriate switch is set to on, the SW USB switches to
the connected keyboard or mouse instantly, without the delay
that normally occurs while the computer recognizes a new
peripheral device. See “Host emulation (SW4 USB Plus only),”
in chapter 3, “Operation”, for more information.
Your RS-232 computer or control system should not be
one of the host devices connected to the input ports. Use
a separate computer for RS-232 communication.
Only Extron products can be controlled via this port.
Wiring the Power Connector
If using a different external power supply from the one provided
with the SW USB, you may need to wire the connector for it.
To wire the power connector,
1. Cut the power supply’s DC output cord to the length
needed.
2. Strip the jacket to expose 3/16" (5 mm) of the conductors.

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.
Exposing less than the recommended amount may
cause the wires to slide out of the connector too
easily, even if they are tightly pinched by the captive
screws.

Contact Closure Control
Contact closure provides another method of input selection.
To enable input selection by contact closure, you can connect a
push-button contact closure device (such as Extron’s CCR 2BLB,
CCR 4BLB, or CCR 204) to the SW USB’s Contact port.
Alternatively, you can manually short one of the pins to ground
(the ground [_] pin is pin 3 for SW2 and pin 5 for SW4 models).
Pin 1 selects input 1, pin 2 selects input 2, etc.
Controlling an Extron A/V switcher in Loop 0 mode
For applications in which the SW USB is connected to an Extron
A/V switcher that can be controlled via RS-232, input selection
on both switchers can be done by contact closure (as well as
by the SW USB front panel buttons and the RS-232 interface).
To select inputs on the A/V switcher via contact closure, the
SW USB must be in Loop 0 mode (in other words, the SIS
command ELOOP0
If the SW USB is in Loop 0 mode and an Extron A/V switcher
is connected to the RS-232 Pass Thru port, an input selection
command issued via contact closure selects the same input on
both the SW USB and the connected switcher.

Operations
Powering on the switcher
To power on the SW USB,
1. Connect all input and output devices to the switcher’s rear
panel connectors and, if desired, connect a host PC to the
RS-232 port. (See chapter 2, “Installation,” for information
on the rear panel connections.)
2. Plug the power supply into the two-pole captive screw
power connector on the rear panel.
The unit performs a self-test, during which the Exec Mode
LED and the front panel Input LEDs each blink once in
sequence from left to right. If the self-test completes with
no errors, the LED for the most recently selected input
remains lit.
3. Select input 1, and power up the PC connected to input 1.
4. Repeat step 3 for all remaining inputs to which PCs are
connected.
Selecting an input
SW USB inputs can be selected by using:
• The front panel buttons
• Contact closure
• SIS commands
Selecting an input from the front panel
To select an input from the front panel, press the desired input’s
button. The LED corresponding to the selected input button
lights.
After an input is selected, the LED remains lit until a new input

Selecting an input using contact closure
Use one of the following methods to select an input via contact
closure:
•Using a contact closure device: If a two- or four-button
contact closure device is connected to the SW USB’s
Contact port, press the button on the device that
corresponds to the SW USB input that you want to select
(the rst button on the left selects input 1, the second
button selects input 2, etc.).
•Using a jumper wire: On the Contact port, insert one end
of a small piece of wire into the ground (_) port and the
other end into the port with the desired input number (1, 2,
3, or 4).
•Using an IR 102: Refer to your IR 102 User’s Manual for
this procedure.
Selecting an input using SIS commands
You can also select an input via an RS-232 connection, using SIS
commands. See chapter 4, “SIS Conguration and Control,” for
a list of available SIS commands and their explanations.
If an Extron A/V switcher is connected to the RS-232 Pass
Thru port, the SIS commands that you enter can also be passed
through to the connected switcher, even if the connected
switcher has more inputs than the SW USB (see the next section).
Issuing commands to an Extron A/V switcher via
the RS-232 Pass Thru port
You can congure the SW USB to pass commands through
the RS-232 Pass Thru port to a connected A/V switcher in the
following modes:
•Loop 1 mode: SIS commands that are issued to the
SW USB via an RS-232 interface (such as HyperTerminal)
on a computer or control system connected to the
SW USB’s RS-232 port can be passed through to an A/V
switcher connected to the RS-232 Pass Thru port.
Loop 1 mode is the default mode. If you need to switch
(where X! is the input number) can be issued to the
SW USB and the connected A/V switcher via the buttons
on the SW USB front panel, contact closure, or the RS-232
interface.
To enable Loop 0 mode, enter the SIS command

SIS command processing in Loop 1 mode
When an A/V switcher is connected to the RS-232 Pass Thru
port and Loop 1 mode is enabled, the available SIS commands
are processed in one of the following ways:
•Passed through to the A/V switcher without being acted
on by the SW USB
•Performed by the SW USB and not passed through to the
A/V switcher
•Performed by the SW USB and passed to the A/V switcher,
which also performs them. This applies only to the input
selection command X! !.

Sending commands to an A/V switcher using contact
closure
In Loop 0 mode, you can select an input on the SW USB by
shorting the equivalent pin on the Contact port to ground (either
by pressing a button on a connected contact closure device or by
connecting a jumper between pin 1, 2, 3, or 4 and _ [ground]).
Shorting the pin to ground issues an input selection command to
the SW USB, which passes the SIS command through its RS-232
Pass Thru port to the A/V switcher. The switcher then switches
to the equivalent input.
For example, if you wanted to select input 1 on the
A/V switcher, you would short pin 1 to ground on the
SW USB Contact port. The SW USB switches to input 1 and,
simultaneously, the RS-232 Pass Thru port passes the SIS
command 1! to the A/V switcher, which also switches to input 1.
The following table shows the SIS commands that are issued
when inputs are selected by contact closure:

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 SW USB is in executive
mode, RS-232 and contact closure remain available.
To lock the front panel, press and hold Input buttons 1 and
2 simultaneously for 5 seconds, then release them. The red

Resetting
To reset the switcher to its factory default settings from the front
panel,
1. Disconnect power from the SW USB.
2. Press and hold the Input 1 button while applying power to
the unit.
The Input LEDs blink three times to indicate that a reset
has occurred. The input selection defaults to input 1, and
the Input 1 LED lights.
Host emulation (SW4 USB Plus only)
The SW4 USB Plus model provides host emulation to peripheral
devices on the output of the switcher. If a keyboard and/
or a mouse is connected to output port 3 or 4, and the Host
Emulation DIP switch(es) are set to on, the SW USB emulates
a host PC to the connected peripheral device. The keyboard/
mouse connected to the switcher’s port 3 or 4 still responds as if
it were attached directly to the computer on the selected input.
Host emulation allows instant communication of the emulated
ports when the SW USB switches to another input, by
eliminating the delay that normally occurs when a computer
recognizes a new device.
Setting up for host emulation
Host emulation is enabled via the Host Emulation DIP switches
on the rear panel. To enable host emulation,
1. Connect a keyboard, a mouse, or both to output port 3
and/or 4. The SW4 USB Plus can emulate a keyboard
and a mouse simultaneously. Either type of device can be
connected to either or both of the two emulation ports (3
and 4).

The SW4 USB Plus can emulate a host only to a standard
keyboard and a standard mouse. The emulation feature is
not supported with non-standard keyboards or mice, such as
devices that require additional drivers.
USB devices other than standard keyboards and mice can be
connected to output ports 3 and 4, but are not supported by
the emulation feature. If you plan to use such devices, set the
Host Emulation DIP switches to off. Examples of non-standard
keyboards or mice include media keyboards or ve-button mice.
Operation, cont’d
Troubleshooting
If the SW USB detects a non-standard keyboard and/or mouse,
an error condition may occur in which the Exec Mode LED
blinks and the SW USB reboots in a repeating cycle. If this
happens, set the host emulation DIP switch(es) to off, and wait
for the switcher to reboot.
You will not be able to use host emulation with that keyboard or
mouse.
Peripheral emulation (SW4 USB Plus only)
In addition, the SW4 USB Plus emulates a mouse and keyboard
to the computer or other input device that is connected to
the selected input port. This emulation of peripheral devices
is constant, whether or not a keyboard or mouse is actually
connected to these ports, facilitating problem-free boot-up.
Keyboard and mouse emulation is always present on the inputs
of the switcher.

The SW USB can be remotely set up and controlled via a host
computer or other device (such as a control system) that is
attached to the rear panel RS-232 port. (See “Wiring for RS-232
Communication” in chapter 2, “Installation,” for information
on connecting to this port.) You can issue Simple Instruction
Set (SIS) commands to the switcher from your computer using
using the RS-232 interface with a communication software
program such as DataViewer or HyperTerminal.
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. 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 SW USB 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 SW USB-initiated message is displayed:
(C) Copyright 2008, Extron Electronics SWn USB Switcher
Series, Vx.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 SW USB returns an error response to the host. Error
response codes and their descriptions are:
E01 – Invalid input channel number (out of range)
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
valid ASCII and hexadecimal command codes, the switcher’s
responses to the host, and a description of the command’s
function or the results of executing the command.
The ASCII to HEX conversion table below is for use with the
command/response table.

Loading the firmware to the SW USB using the
Firmware Loader
To load a new version of rmware from your computer to your
SW USB using the Extron Firmware Loader software, your
computer’s serial port must be connected to the switcher ’s
RS-232 serial port. See “Rear Panel Features,” in chapter 2,
“Installation,” for information on connecting to the serial port.
1. If you have not already done so, download and install the
Firmware Loader executable installer le to your computer
(see “Downloading and installing the Firmware Loader,”
earlier in this chapter).
2. If necessary, download the latest SW USB rmware version
and install it on your computer (see “Downloading and
installing the rmware,” on the previous page).
3. Open the Firmware Loader via your desktop Start menu
by making the following selections: Start > All Programs >
5. On the rst screen that appears, select the RS-232 tab.
6. From the drop-down menus on the RS-232 screen, select
your model name (SW2 USB, SW4 USB, or SW4 USB Plus),
the appropriate COM port number, and 9600 for the baud
rate.
7. Click OK. The rmware selection screen appears.
8. Click Browse to open the Choose Firmware File window,
and locate the rmware le that you downloaded. (By
default, the le is placed at
c:\Program Files\Extron\Firmware when downloaded

message “Transfer Complete!” is displayed, and the new
rmware version number appears in the Current Unit
Information eld.
Problem solving
If you inadvertently load an incorrect version of rmware to
the SW USB (e.g., version 1.01 instead of 1.02), you can load the
desired version, which overwrites the previous one.
If the rmware that you attempt to load is corrupt, the switcher
reverts to the most recently loaded version that was functional.
To load the new rmware, obtain another copy of the desired
version and perform the upload procedure again.
Click Exit to close the Firmware Loader.
