About this Manual

This manual describes the Extron SW2 USB, SW4 USB, and SW4 USB Plus switchers, and discusses how to install, configure, 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 pass- through, 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 specification. In addition, the switchers are USB 2.0 compatible, and are compatible with all previous USB data rate specifications, 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 simplified 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 specification.

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 Configuration 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.
