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.
