About this Guide
This guide describes the SW DVI Plus Series switchers and discusses how to install, configure,
and operate them.
In this guide, the term “SW DVI Plus Series” refers to all SW DVI Plus models, with or
without audio. “Switcher” and “SW DVI Plus” are used interchangeably to refer to any
single unit.
The SW DVI Plus Series consists of the following eight models:
SW2 DVI Plus SW2 DVI A Plus
SW4 DVI Plus SW4 DVI A Plus
SW6 DVI Plus SW6 DVI A Plus
SW8 DVI Plus SW8 DVI A Plus
The number following SW indicates the number of inputs; “A” indicates an audio product.
For example, the SW6 DVI A Plus is a six-input switcher with audio.
About the SW DVI Plus Series
The Extron SW DVI Plus Series are two, four, six, and eight input, one output, single-link
Digital Visual Interface (DVI) switchers that select among multiple DVI-D video input signals
to output to a single compatible display device. The SW DVI A Plus switchers additionally
switch audio signals. All switchers accept and route computer resolutions of up to
1920x1200 or 1080p @ 60 Hz and have pixel bandwidths of up to 165 MHz.
The SW DVI Plus switchers can be controlled via the front panel, the RS-232 interface, or the
optional IR 102 Remote Control. You can select inputs by pressing the front panel buttons,
enabling auto-input switching, entering Simple Instruction Set (SIS™) commands via RS-232,
or pressing buttons on the IR 102.
NOTE: The SW DVI Plus Series switchers are not compatible with HDCP (High-bandwidth Digital
Content Protection) signals. If the display device exhibits a flashing black or blue screen, snow,
or other display distortion, it may be receiving an HDCP-encrypted signal.
SW DVI Plus Series • Introduction 1
Features
• Auto-input switching — The SW DVI Plus Series can be congured to automatically
switch to the active input when the switcher detects a signal. If multiple input signals are
present, the switcher switches to the highest numbered active input.
• Signal detection LEDs — Each input is represented by an LED on the front panel. Each
LED lights if a signal is present for its input.
• Independent input equalization — High or low equalization levels for each input can
be selected via the Input EQ DIP switches on the front panel. This reduces the need for
additional signal conditioning equipment to compensate for a degraded or poor quality
signal.
• EDID Minder — EDID (Extended Display Identication Data) consists of the resolution,
refresh rate, and pixel clock information of a display device. The EDID Minder manages
this information between the digital output device and all the input sources. By
maintaining continuous EDID communication with all input sources, the EDID Minder
ensures that all DVI sources power up properly and maintain their video outputs,
whether or not an active signal is displayed.
Either of the following EDID modes can be selected by SIS commands:
• Automatic, in which the SW DVI Plus reads the EDID data when a display is
connected and stores the data in memory (default mode)
• User-assigned, in which you can assign one of 15 factory-provided les of EDID
information to each input. The EDID does not change if a different display device is
connected. This mode is useful for trouble-shooting purposes.
Each time power is applied to the output device or the display is replaced, the SW DVI
Plus either reads the EDID information from the display or reloads the user-assigned
EDID information. It then writes the information to non-volatile memory on the inputs.
The input devices can read this information as they reboot (see “EDID Modes” in the
“Operation” section for more information).
• Power supply — An external 12 VDC power supply with a 2-pole captive screw
connector accepts 100 to 240 VAC.
• Rack and furniture mounting — The SW DVI Plus Series can be mounted on a rack
shelf or under a desk or podium with an optional mounting kit.
• RS-232 control — The switcher can be controlled via SIS commands issued through an
RS-232 computer interface.
• IR remote control (optional) — The hand-held IR 102 Remote Control can control the
SW DVI Plus via infrared signals that it sends to the switcher from a distance of up to
30 feet (9 m).
• Front panel security lockout (executive mode) — To prevent unauthorized access
to the switchers, front panel lock mode can be enabled via the front panel or SIS
commands. When the switcher is in lock mode, all front panel controls are disabled
(RS-232 and IR control remain available).
• Universal Switcher Control Program — The Windows®-based Extron Universal
Switcher Control Program, which communicates with the switcher via the RS-232 port
(non-audio SW2 and SW4 models) or the Remote/Auto-SW port (all other models),
provides an alternative way to congure and operate the SW DVI Plus switcher. The
program is compatible with Windows 2000, Windows XP, Windows 7, or higher
versions.

a Video input connectors — Connect DVI-D video input devices to these female DVI-I
connectors.
NOTES: • The connectors on the switcher rear panel are DVI-I. However, the switcher
accepts only single-link DVI-D signals.
• Appropriate DVI-D to HDMI cables or adapters are required for HDMI
signal input and output.
• The SW DVI Plus Series switchers are not compatible with HDCP signals.
For each of these inputs there is a DIP switch on the front panel to set the equalization
level of the input, which compensates for weak or noisy signals (see “Front Panel
Features” on page 12).
EDID information (display resolution, refresh rate, and pixel clock rate), when read from
the output display or entered by a user, is written to memory on each input, allowing
the source to perform as if connected to the display, even when it is switched away
from it. (For more information on EDID, see “EDID Modes” on page 15.)
NOTE: If power is recycled to the display, or if a new display is connected, the
source may need to be rebooted to read the new EDID.
b Video output connector — Connect a DVI-D output to this female DVI-I connector.
• If automatic EDID mode is enabled, the EDID information is read from the
connected output device via this connector and is written to memory on each input
whenever a display is powered on and connected this port.
• If user-assigned mode is in effect, the information in the assigned EDID le is
loaded into memory when a display is connected and powered on.
NOTE: The EDID information is also read and stored whenever power is recycled to
the connected output device or when the output device is replaced.
SW DVI Plus Series • Installation 6
c RS-232 connector (SW2 and SW4 DVI Plus non-audio models only) — For RS-232
control, connect your computer serial port to this 9-pin female D connector. (For more
information, see “Wiring for RS-232 Control” on page 9.)
d Remote and auto-input switching connector — This 5-pole, 3.5 mm captive screw
connector (labeled “Remote/Auto-SW”) can be used for RS-232 communication with
the switcher and to enable auto-input switching.
• To connect for RS-232 control on all models except the non-audio SW2 and
SW4 DVI Plus, connect the Tx (transmit), Rx (receive) and G (ground) pins to your
computer serial port (see “Wiring for RS-232 Control”).
• To enable auto-input switching, short pins 4 and 5 of this connector together.
In auto-input switch mode, the switcher automatically switches to the highest
numbered active input (see “Enabling Auto-input Switching” on page 10).
NOTE: The SW2 and SW4 DVI Plus non-audio models do not have this
connector. Auto-input switching on those models is enabled and
disabled via an SIS command (see the “Input Selection Mode”
commands in the Command and Response Table for SIS commands,
“Remote Configuration and Control” section).
e Audio output connector (SW DVI A Plus models only) — Connect the audio
cable from your output device to this 5-pole, 3.5 mm captive screw connector for
balanced (+6 dB) or unbalanced (0 dB) audio (see “Wiring the Audio Connectors
(SW DVI A Plus Models)” on page 8).
NOTE: If the output device is wired for unbalanced audio, the gain is unity. If the
f Audio input connectors (SW DVI A Plus models only) — Connect the audio cables
from your input sources to these 3.5 mm TRS mini jacks for unbalanced stereo audio.
g Power connector — Plug the provided external 12 VDC power supply into this 2-pole,
3.5 mm captive screw connector.
Wiring the Power Connector
If using a different external power supply from the one provided with the SW DVI Plus, you
may need to wire the power supply connector as follows:
1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
CAUTIONS: • Exposing more than 3/16 inch (5 mm) of the copper wires could
output is wired for balanced audio, a +6 dB gain is applied.
allow the stripped wires to touch each other, causing a short circuit.
This could result in the external DC power supply overheating and
burning.
• Stripping the wires to expose less than the recommended amount
may cause them to slide out of the connector too easily, even if they
are tightly pinched by the captive screws.

3. Slide the leads into the supplied 2-pole captive screw plug and secure them, using a
small screwdriver.
CAUTION: Do not tin the stripped power supply leads before attaching the captive
screw plug to them. Tinned wires are not as secure in the captive screw
connectors and can be easily pulled out. They may also break after
being bent several times.
4. To verify the polarity of the power cord before connecting it, plug in the power supply
with no load and check the output with a voltmeter.
WARNING: Keep the two power cord wires separate while the power supply is
plugged in. Remove power before wiring.
5. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.
