This guide provides basic instructions for setting up and
operating the Extron SW DVI Plus and SW DVI A Plus
Series switchers.

Installation

Step 1 — Mount the unit

Turn off or disconnect all equipment power sources and mount the switcher as required.

Step 2 — Connect video inputs

Connect source devices to one or more DVI video input connectors.
Only single-link DVI-D signals are supported. If necessary, set the
equalization DIP switches for each input to High (up) to compensate
for a weak signal, or to Low (down), if all signals are strong.

Step 3 — Connect video outputs

Connect a DVI-D display device to the DVI-I video output connector.

Step 4 — Connect audio inputs (SW DVI A Plus models

only)

Plug the input devices’ audio connectors into the 3.5 mm TRS audio
input jacks for unbalanced audio. See the wiring diagram at right.

Step 5 — Connect audio outputs (SW DVI A Plus models only)

Connect the switcher’s audio output to a suitable audio device. Wire the 5-pole connector as
shown below.

• 1#, to select normal switch mode

For explanations of all SIS commands, refer to chapter 4
of the SW DVI Plus Series User’s Manual.

All other models:

Step 7 — Connect RS-232

• SW2 and SW4 DVI Plus (non-audio) models: Connect an RS-232 cable
from your computer to this female 9-pin D connector. Protocol for this
port is 9600 baud, 8 data bits, 1 stop bit, no parity. Wire the connector as
follows: pin 2 = Tx, pin 3 = Rx, pin 5 = Gnd.

• All other models:
Connect a bare wire-to-female
9-pin D RS-232 cable to pins 1, 2,
and 3 of one of the 5-pole captive
screw plugs. Insert the plug into
the Remote/Auto-SW shared
connector, and connect the cable to
the computer’s serial port. See the
illustration at right.

Step 8 — Wire power
connector

If using a different 12 V, 1 A external
power supply from the one that is
included (already wired), attach the
provided two-pole captive screw
connector to the power supply as
shown below.
