• About this Guide This guide describes the Extron SW2 USB, SW4 USB, and SW4 USB Plus switchers and provides instructions on installing, configuring, and operating them. The terms “SW USB” and “switcher” are used throughout this guide to refer to all models.
RS-232 control and pass-through — The SW USB switcher can be controlled by • Simple Instruction Set (SIS ) commands received via an RS-232 interface. These SIS ™ commands can be sent to an RS-232 controllable Extron AV switcher attached to the “SIS Programming and Control”...

Emulation DIP switches — (SW4 USB Plus only) These DIP switches enable host emulation to a keyboard and 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 Plus switches to the connected keyboard or mouse instantly, without the delay that normally occurs while the computer recognizes a new peripheral...

Use the supplied tie-wrap to strap the power cord to the extended tail of the connector. The figure below shows how to wire the power connector. Smooth Ridges SECTION A–A Power Supply Output Cord Tie Wrap 3/16” (5 mm) Max. Captive Screw Connector Figure 4.
Wiring for RS-232 Communication RS-232 Port The 3-pole, 3.5 mm captive screw connector labeled “RS-232” is used for optional RS-232 communication between the SW USB and a computer 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 AV switcher that is plugged into the RS-232 Pass Thru port.
RS-232 Pass Thru Port The RS-232 Pass Thru port loops the signal received at the SW USB RS-232 control port, the Contact (closure) port, or the front panel input buttons through the RS-232 Pass Thru port to send SIS commands to another Extron AV switcher. NOTE: Only Extron products can be controlled via this port.

Selecting an input on an AV Switcher via contact closure To make input selections on a connected AV switcher via contact closure, you must place the SW USB in loop 0 mode. When the ground pin of the Contact port is connected to one of its other pins by by one of the methods described on the previous page, the SW USB sends the input selection SIS command X! (where X! is the input number) through...

Example: When a control system issues an SIS input selection command (select input 1), (select input 2), (select input 3), or (select input 4), the SW USB switches to the corresponding input.The SW USB also passes the SIS input selection command through the RS-232 Pass Thru port, causing the same input to be selected on the AV switcher.
Resetting To reset the switcher to its factory default settings from the front panel: Disconnect power from the SW USB. Press and hold the Input 1 button while reapplying 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.
NOTES: • If two mice or two keyboards are connected to output ports 3 and 4, and the appropriate emulation DIP switch is set to On, the switcher emulates a host to only one port. • 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 •...
