Installation Overview
To install and set up the SW USB switcher:
1. (Optional) Mount the switcher to a rack shelf or furniture (see “Mounting the SW USB
Series Switcher” in the “Reference Information” section).
2. Connect host devices to one or more SW USB Switched Input type B connectors, using
cable lengths of up to 15 feet (4.5 m).
3. Connect one or more peripheral USB devices to the SW USB Output Hub type A
connectors, using USB cable lengths of up to 15 feet (4.5 m).
4. (Optional) Connect an RS-232 cable between the SW USB RS-232 port and a host
computer or control system (see “Wiring for RS-232 Communication” on page 8).
NOTE: The computer that you use for RS-232 control should not be one of the
host devices connected to any of the input ports.
5. (Optional) Connect an external Extron AV switcher to the RS-232 Pass Thru port. You
can then control this switcher via commands sent through this port.
6. (Optional) Wire one of the provided 3-pole or 5-pole captive screw plugs to a 2-button
or 4-button contact closure device, and connect the device to the SW USB Contact port
(see “Setting Up Contact Closure Control” on page 9).
7. If using a different power supply from the one that was provided, wire a 2-pole captive
screw plug to the external power supply (see “Wiring the Power Connector” on
page 6).
8. SW4 USB Plus only: If desired, attach a keyboard, a mouse, or both to output ports
3 or 4, and set the appropriate DIP switches for host emulation (see “Host Emulation
[SW4 USB Plus Only]” in the “Operation” section).
