Introduction
This section gives an overview of the Extron SW USB Pro Series switchers. Topics include:
• About this Guide
• The SW USB Pro Series Switchers
• Features
• USB System Architecture
• Application Diagrams
About this Guide
This guide provides instructions on installing, configuring, and operating the Extron SW2
USB Pro and the SW4 USB Pro Series switchers and them. The terms “SW USB Pro” and
“switcher” are used throughout this guide to refer to all models.
The SW USB Pro Series Switchers
The SW USB Pro Series are two- and four-input USB switchers that allow for two or four
host computers to switch among up to four peripheral USB devices (such as mass storage
devices, keyboards, mice, and other human interface devices [HIDs]) with data rates up to
10 Gbps. The switchers act as active USB hubs, supplying power to attached devices. In
addition, the switchers are USB 3.2 compatible, including SuperSpeed USB 5 Gbps and
10 Gbps, and are backward-compatible with all previous USB data rate specifications.
The series consists of four models:
• SW2 USB Pro
• SW4 USB Pro
• SW2 USB Pro Non-LAN
• SW4 USB Pro Non-LAN
The non-LAN models are identical to the standard models except that they do not contain
LAN ports. Ethernet functionality is available via IP over USB (see Ethernet over USB
starting on page18 for more information).
Features
A number of specialized features help to streamline system integration, including port status
indication, front panel security lockout, and multiple control points.
• Outputs — One female USB-C and three female USB Type A connectors.
• SuperSpeed USB 10G compatible — Supports newer USB 3.2 speed devices and is
backwards compatible with all prior USB versions.
• Hot Key, Auto, and manual switching capability — Provides multiple ways to
switch between hosts to ensure easy integration and control for many AV environments.

SW USB Pro Series • Introduction 2
• Four port output hub with USB‑C and Type A connections — Enables
simultaneous connection to multiple peripheral devices with USB-C or Type A
connections such as mass storage devices, keyboards, mice, or other Human Interface
Devices (HIDs).
• Supports selectable Host and Peripheral emulation — Emulates uninterrupted
connection between host, keyboard, and mouse devices. This feature enables devices
to remain functional when switching between inputs.
• Front panel selection buttons and status indicators — Facilitates easy control and
troubleshooting from front panel.
• Built‑in web pages — Enables the use of a standard browser for device monitoring
and troubleshooting over an intuitive web interface.
• Ethernet and RS‑232 control options — Provides multiple control options for pro AV
environments.
• Front panel security lockout — Prevents unauthorized use in non-secure
environments. In lockout mode, a special button combination is required to operate the
switcher from the front panel.
• Rack‑mountable, 1U half rack width metal enclosure
• External Extron Everlast power supply included — Provides worldwide power
compatibility with high-demonstrated reliability and low power consumption.
• Extron Everlast Power Supply is covered by a 7‑year parts and labor warranty
USB System Architecture
A USB system architecture refers to the physical bus topology of USB devices connected
to a host device. USB devices include USB hubs, USB peripheral devices, or compound
devices (devices with a combination of USB hubs and USB peripheral devices built into it).
The system is organized in a tiered star topology to prevent multiple or circular attachments
to the bus. Each tier represents a degree of separation from the host device. Per USB
specifications, there are seven supported tiers, starting with the host device (or root hub)
occupying the first tier.
NOTE: Do not connect more than five daisy-chained hubs to the root hub. The
architecture does not support peripheral devices connected to USB hubs occupying
the seventh tier.

Figure 1. Tiered Star Topology Example for a Computer with Four Monitors
NOTE: Some computers include multiple hubs already connected to each other,
occupying multiple tiers in the topology. For example, many computers with USB
ports on the front and rear panels or computers with a built-in USB hub and a
compound USB peripheral device (such as a touch display) occupy two tiers. For
information about USB hubs used in Extron products, see the USB Hub Usage Chart
at www.extron.com.
To review the USB system architecture, count all the cascading hubs (including USB hubs
enclosed in computers and compound devices) between the host device and the last USB
peripheral device.
NOTE: If the host device runs Windows®or macOS™ operating systems, use the
following programs to view the hierarchical relationships between USB devices:
• Windows: Device Manager
• macOS: System Profiler or System Information

Figure 7. Wiring the Power Connector
ATTENTION:
• Always use a power supply supplied and or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the end product.
• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.
L’utilisation d’une source d’alimentation non autorisée annule toute conformité
réglementaire et peut endommager la source d’alimentation ainsi que le produit
final.
• The two wires must be kept separate while the power supply is plugged in. Remove
power before wiring.
• Les deux cordons d’alimentation doivent être tenus à l’écart l’un de l’autre quand
l’alimentation est branchée. Couper l’alimentation avant de faire l’installation
électrique.
• If not provided with a power supply, this product is intended to be supplied by a
power source marked “Class 2” or “LPS” and rated at 12 VDC and a minimum of
1.6 A.
• Si ce produit ne dispose pas de sa propre source d’alimentation électrique, il doit
être alimenté par une source d’alimentation de classe 2 ou LPS et paramétré à 12 V
et 1.6 A minimum.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
• Cette installation doit toujours être en accord avec les mesures qui s’applique au
National Electrical Code ANSI/NFPA70, article725, et au Canadian Electrical Code,
partie1, section16. La source d’alimentation ne devra pas être fixée de façon
permanente à une structure de bâtiment ou à une structure similaire.

SW USB Pro Series • Installation 9
ATTENTION:
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the unit. The ridges on the side of the cord identify the power
cord negative lead (see figure7 on page8).
• La polarité de la source d’alimentation est primordiale. Une polarité incorrecte
pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté du
cordon permettent de repérer le pôle négatif du cordon d’alimentation (voir figure7
à la page 8).
• To verify the polarity before connection, plug in the power supply with no load and
check the output with a voltmeter.
• Pour vérifier la polarité avant la connexion, brancher l’alimentation hors charge et
mesurer sa sortie avec un voltmètre.
• 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 connectors and could be pulled out.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les
dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont un peu plus longs,
les câbles exposés pourraient se toucher et provoquer un court circuit. S’ils sont un
peu plus courts, ils pourraient sortir, même s’ils sont attachés par les vis captives.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling
spaces or in wall cavities.
• Sauf mention contraire, les adaptateurs AC/DC ne sont pas appropriés pour une
utilisation dans les espaces d’aération ou dans les cavités murales.
Wiring for RS-232 Communication
The 3-pole, 3.5 mm captive screw Remote RS-232 connector enables optional RS-232
communication between the SW USB Pro and a computer or control system. The control
system plugged into this port can issue SIS commands to the SW USB Pro.
To connect your computer or control system to the RS-232 connector, use a female 9-pin
D-to-bare-wire RS-232 cable, such as an Extron UC50 Universal Projector Control cable.
1. Wire the unterminated end of the RS-232 cable to one of the provided 3-pole captive
screw plugs.
2. Plug the wired 3-pole connector into the RS-232 receptacle on the SW USB Pro rear
panel.
Do not tin the wires!

SW USB Pro Series • Operation 12
AExec Mode LED — This green LED lights when front panel lock mode (executive
mode) has been selected, and that input selections cannot be made from the
front panel (see Locking and Unlocking the Front Panel (Executive Mode) on
page14). This can be configured via SIS (see Front Panel Lockout (Executive
Mode) on page22) or PCS (see the SW USB Pro Help File).
BAuto Switch LED — This LED lights when auto-switching is enabled (see
Auto Switching on page14 to set up automatic input selection).
CUSB Config port — Connect a USB cable (USB Type A to USB-C) between a
computer and this female USB-C port to configure and control the switcher via SIS
commands or PCS, and to update the firmware.
NOTE: The USB-C Config port uses Ethernet over USB communication (see
Connecting the Switcher to the Host on page18 for more information).
DInput Selection buttons and LEDs — Press one of these buttons to select an input
(host) to switch to an output (device). The green LED at the right of each button lights
when the corresponding input has been selected.
If Auto Switch is in effect, these input selection buttons are disabled, but the LEDs
continue to light to indicate the selected input. The input buttons are also used to initiate
a system reset and to enable and disable front panel lockout
EHost LEDs — Each of these green LEDs lights when a host is connected to the
corresponding input port, whether or not the input is selected.
FDevice Status LEDs — Each of these green LEDs lights when a peripheral device
is connected to the corresponding output port and has been enabled by the selected
host.
Powering on the System
To power on the SW USB Pro and connected devices:
1. Connect all input and output devices to the rear panel connectors on the switcher (see
Rear Panel Features starting on page6 for more information).
2. If desired, connect a host PC to the RS-232 port (see Wiring for RS‑232
Communication on page9) or to the front panel USB-C Config port.
3. Plug the power supply into the 2-pole captive screw power connector on the rear panel
(see figure4 and figure5, Aon page 6. The unit performs a self-test, during which
the Exec Mode LED and the front panel host LEDs each blink once in succession from
left to right. If the self-test completes with no errors, the LED for the most recently
selected input remains lit.
4. Select each input and power up the host device connected to it (see Selecting an
Input (Host) on the next page).
