Introduction

About this Manual

This manual describes the Extron SW2 USB, SW4 USB, and SW4 USB Plus switchers, and discusses how to install, congure, 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 specication. In addition, the switchers are USB 2.0 compatible, and are compatible with all previous USB data rate specications, 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 simplied 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 specication.
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-232 control 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 Conguration 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.

Installation Overview

To install and set up the SW USB switcher,
Mount the switcher on a rack shelf or furniture, if desired.
Connect host device(s) to one or more SW USB input
connectors, using USB cable lengths of up to 15' (4.5 m).
Connect one or more peripheral USB devices to the SW USB Output Hub ports, using USB cable lengths of up to 15' (4.5 m).
If desired, connect an RS-232 cable to the SW USB’s RS-232
port and to a host computer or control system. (See “Wiring for RS-232 Communication,” later in this chapter.)
N
Your RS-232 computer or control system should
not be one of the host devices connected to any of the input ports. Use a separate computer for RS-232 communication.
If desired, connect an external Extron A/V switcher to
the RS-232 Pass Thru port. This switcher can then be controlled via commands sent through this port.
If desired, wire one of the provided three-pole captive
screw plugs to a 2-button or 4-button contact closure device, and connect the device to the SW USB’s Contact port. (See “Contact Closure Control,” later in this chapter.”)
If using a different power supply from the one that was
provided, wire the provided two-pin captive screw connector to the external power supply. (See “Wiring the Power Connector,” later in this chapter.)
(SW4 USB Plus only) If desired, attach a keyboard and/or
mouse to output port 3 and/or 4, and set the appropriate DIP switch(es) for host emulation. (See “Host emulation (SW4 USB Plus only),” in chapter 3, “Operation.”

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 = +122 °F, +50 °C) specied 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 — When mounting the equipment in
the rack, ensure that uneven mechanical loading does not cause a hazardous condition.

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.
C
3. Slide the exposed leads into a two-pin captive screw plug
4. To verify the power cord’s polarity before connecting
5. Use the supplied tie-wrap to strap the power cord to the
The gure below shows how to wire the power 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.
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.

Wiring for RS-232 Communication

RS-232 port

The three-pin, 3.5 mm captive screw connector labeled “RS-232” is used for optional RS-232 communication between the SW USB and a PC or control system. The control system plugged into this port can issue commands to the SW USB, which can pass the commands through to an Extron A/V switcher that is plugged into the RS-232 Pass Thru port.
N
To connect your computer or control system to the RS-232 connector, use a male 9-pin, D-to-bare-wire RS-232 cable. One end of the UC cable is terminated with a female 9-pin D connector, and the other end is unterminated.
1. Wire the unterminated end of the RS-232 cable to one of

RS-232 Pass Thru port

The RS-232 Pass Thru port allows you to loop through the Transmit line of the RS-232 control port from the SW USB. This enables you to send SIS commands to another Extron A/V switcher. See chapter 4, “SIS Conguration and Control”, for explanations of these SIS commands.

The SW USB sends SIS commands to the A/V switcher in the following loop-through modes:
Loop 1 mode (default) — In this mode, SIS commands
To enable Loop 1 mode, issue the E 1LOOP} command.
Loop 0 mode — In this mode, the input selection SIS

command X! ! can be issued to the SW USB via contact closure, the SW USB front panel buttons, or the RS-232 interface. The SW USB subsequently passes the command through to a connected A/V switcher.
In Loop 0 mode, you can still issue commands to the
SW USB using the front panel buttons, RS-232, or contact closure in both loop modes. The loop mode selection affects only commands coming through the RS-232 Pass Thru port.

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.
Using the SW USB with a contact closure device and an A/V 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 is selected.

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 Conguration 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 congure 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
the SW USB to this mode, enter the SIS command
E
1LOOP
Loop 0 mode: The input selection SIS command X! !
(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

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:
Contact closure selection
Pin 1 to _ Pin 2 to _ Pin 3 to _ Pin 4 to _
N
When the SW USB is operating in Loop 0 mode,
SIS command sent via RS-232 Pass Thru
1! Select input 1
2! Select input 2
3! Select input 3
4! Select input 4
pressing one of its front panel input buttons or issuing the SIS command X! ! also selects the same input on the A/V switcher.

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 Exec Mode LED on the front panel lights, indicating that executive mode is enabled.

Setting executive mode
To exit executive mode, repeat the procedure described on the previous page. When the SW USB is no longer in executive mode, the red LED turns off.

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).

Emulation
Off (down) Off (down) No emulation
On (up) Off (down) Emulate mouse only
Off (down) On (up) Emulate keyboard only
On (up) On (up) Emulate keyboard and
mouse
Example: In the illustration at right, emulation
is enabled for both a mouse and a keyboard.
If two standard mice or keyboards are connected to output ports 3 and 4, and the appropriate emulation DIP switch is set to on (up), the SW4 USB Plus emulates a host to both ports.
N
When one or both DIP switches are set to on (up), host
emulation follows the attached peripheral device:
When the Mouse DIP switch (switch 1) is set to on
(up), the switcher emulates a host to any standard mouse that is connected to either of the emulation output ports (3 or 4).
When the Keyboard DIP switch (switch 2) is set to
on, the switcher emulates a host to any standard keyboard that is connected to an emulation port.
When both DIP switches are set to on, the switcher
emulates a host to any connected standard mouse and/or keyboard that is connected to port 3 or 4.
Supported peripheral devices
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.

SW USB Series • Operation
SIS Configuration and Control
ASCII to HEX Conversion Table
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.
