Installation Overview

To install and set up the SW USB switcher,

Mount the switcher on a rack shelf or furniture, if desired.

Connect host device(s) to one or more SW USB input

connectors, using USB cable lengths of up to 15' (4.5 m).

Connect one or more peripheral USB devices to the

SW USB Output Hub ports, using USB cable lengths of up

to 15' (4.5 m).

If desired, connect an RS-232 cable to the SW USB’s RS-232

port and to a host computer or control system. (See

“Wiring for RS-232 Communication,” later in this chapter.)

Your RS-232 computer or control system should

not be one of the host devices connected to any of the

input ports. Use a separate computer for RS-232

communication.

If desired, connect an external Extron A/V switcher to

the RS-232 Pass Thru port. This switcher can then be

controlled via commands sent through this port.

If desired, wire one of the provided three-pole captive

screw plugs to a 2-button or 4-button contact closure

device, and connect the device to the SW USB’s Contact

port. (See “Contact Closure Control,” later in this

chapter.”)

If using a different power supply from the one that was

provided, wire the provided two-pin captive screw

connector to the external power supply. (See “Wiring the

Power Connector,” later in this chapter.)

(SW4 USB Plus only) If desired, attach a keyboard and/or

mouse to output port 3 and/or 4, and set the appropriate

DIP switch(es) for host emulation. (See “Host emulation

(SW4 USB Plus only),” in chapter 3, “Operation.”

Mounting the SW USB Series Switcher

The SW USB Series switcher can be set on a table, mounted on a

rack shelf, or mounted under a desk, podium, or table.

Tabletop use

Four adhesive rubber feet are included with the SW USB

switcher. For tabletop use, attach one foot at each corner on

the bottom of the unit, and place the switcher in the desired

location.

Rack mounting

For optional rack mounting, do not install the rubber feet.

Mount the switcher on any of the following rack shelves:

UL rack mounting guidelines

The following Underwriters Laboratories (UL) guidelines

pertain to the safe installation of the equipment in a rack.

1. Elevated operating ambient temperature — If the

equipment is installed in a closed or multi-unit rack

assembly, the operating ambient temperature of the

rack environment may be greater than room ambient

temperature. Therefore, install the equipment in an

environment compatible with the maximum ambient

temperature (Tma = +122 °F, +50 °C) specied by Extron.

2. Reduced air ﬂow — Install the equipment in a rack so that

the amount of air ow required for safe operation of the

equipment is not compromised.

3. Mechanical loading — When mounting the equipment in

the rack, ensure that uneven mechanical loading does not

cause a hazardous condition.
