Installation Overview

To install and set up the SW USB switcher,

1Mount the switcher on a rack shelf or furniture, if desired.

2Connect host device(s) to one or more SW USB input connectors, using USB cable lengths of up to 15' (4.5 m).

3Connect one or more peripheral USB devices to the

SW USB Output Hub ports, using USB cable lengths of up to 15' (4.5 m).

4If 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.)

NYour 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.

5If 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.

6If 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.”)

7If 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.)

8(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.”

9Power on the USB peripheral devices, if applicable.

10Power on the SW USB switcher.

11Power on the host device(s).

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:

•RSB 123 — 1U, 3.5" Deep VersaTools® Basic Rack Shelf (part #60-604-20)

•RSF 123 — 1U, 3.5" Deep VersaTools Rack Shelf Kit (part #60-190-20)

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) specified by Extron.

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