2
input connectors.
Connect an output device to the SW2/SW4 output
3
connector.
Connect the audio connectors of your input device(s) to
4
the SW2/SW4 audio input 3.5 mm TRS mini jacks.
Wire one of the provided 5-pole captive screw plugs to
5
your audio output cable, and connect your output device's
audio input to the SW2/SW4 captive screw audio output
connector.
Insert the other provided captive screw plug into the
6
Remote/Auto-sw connector on the SW2/SW4 rear panel.
Wire your RS-232 cable to pins 1, 2, and 3 of this plug, and
connect the other end of the cable to your computer. (See
"Wiring for RS-232," later in this chapter.)
If using autoswitching, jumper-connect together pins 4
7
and 5 of the 5-pin captive screw plug that you plugged
into the Remote/Auto-Sw connector in step
"Enabling autoswitching," later in this chapter.)
If necessary, wire the provided 2-pin captive screw
8
connector to the external power supply. (See "Wiring the
Power Connector," later in this chapter.)
Power on the output display.

Mounting the SW DVI A Series
The SW DVI A Series switcher can be set on a table, mounted on
a rack shelf, or mounted under a desk, podium, or table.
Tabletop use
Four self-adhesive rubber feet are included with the SW2/SW4.
For tabletop use, attach one foot at each corner on the bottom of
the unit, and place the switcher in the desired location.

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 = +113 °F, +45 °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 — Mount the equipment in the rack
so that a hazardous condition is not achieved due to
uneven mechanical loading.
4.
Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this
concern.
5.
Reliable earthing (grounding) — Maintain reliable
grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).
