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
SW4 DVI Plus
SW6 DVI Plus
SW8 DVI Plus
SW2 DVI A Plus
SW4 DVI A Plus
SW6 DVI A 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.

Features
•
Auto-input switching — The SW DVI Plus Series can be configured 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 Identification 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 files 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.
“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 configure 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
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 file 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.

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
output is wired for balanced audio, a +6 dB gain is applied.
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
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.

Enabling Auto-input Switching
You can set up the SW DVI Plus to automatically select the active connected input based on
detection of a video sync signal. If two or more inputs are active, the input with the highest
number is selected (for example, input 8 on an SW8 DVI Plus switcher). When auto-input
switching is in effect, the green Auto Switch LED on the front panel lights and the front
panel input selection buttons are disabled.
NOTE: Audio and video cannot be switched separately when auto-input switching is
enabled.
SW2/SW4 DVI Plus (Non-audio) Models
On the non-audio SW2 and SW4 DVI Plus, auto-input switching is enabled or disabled via
beginning on page 18, for information on using SIS commands).
• 1#selects normal switch mode.
• 2#selects auto-input switch mode.
All Other Models
To enable auto-input switching on the SW2, SW4, SW6, and SW8 DVI A Plus models and on
the SW6 and SW8 DVI Plus non-audio models:
1. Cut a small piece of wire to use as a jumper.
2. Insert the ends of the wire into slots 4 and 5 of the provided 5-pole captive
screw plug, connecting pins 4 and 5 together.
3. Use a small screwdriver to tighten the two screws of the plug above pin
slots 4 and 5, so that the jumper wire ends remain securely in place (see
the illustration at right).
4. Insert the plug into the 5-pole Auto-SW captive screw connector on the
switcher rear panel.

Operations
Powering On the Switcher
Follow these steps to power on the SW DVI Plus:
1. Connect all input devices and the output to the switcher rear panel connectors (see
connections).
2. Power on the output device.
3. Plug the power supply into the 2-pole captive screw power connector on the rear panel.
•
The unit performs a self-test, during which the front panel Auto Switch and Input
LEDs each blink once in sequence from left to right. When the self-test completes,
the LED for the most recently selected input remains lit.
•
The switcher reads the available EDID information from either the connected output
device or the user specifications and writes it to memory on each input.
NOTE: The EDID is also read and stored again whenever power is recycled
to the display device or the device is replaced. You must reboot your
computer and other input devices for them to read the new EDID.
4. Power on the input devices.
Selecting an Input
To switch an input to the output, press the desired input button on the front panel (ensure
that auto-input switching is not enabled). The LED corresponding to the selected input
button lights.
•
To determine the current configuration, check the front panel input LEDs. The one that
is lit indicates the selected input. The LED remains lit until a new input is selected.
•
•
Only one input can be switched to the output at a time.
When only audio is selected for an input via SIS command (audio breakaway), the LED

Other ways to select an input include using SIS commands (see the Input Selection
Configuration and Control” section) or the optional IR remote control (see “Using
the Optional IR 102 Remote Control”). Front panel input selection is disabled when
auto-input switching is in effect.
Using the Optional IR 102 Remote Control
The optional hand-held IR 102 Remote Control (part number 70-224-10) lets you remotely
perform functions that are also available through the front panel buttons and SIS
commands.
The IR receiver sensor on the front panel is located to the right of the Auto Switch Active
LED. It receives signals from the remote control if they are sent from within a 40-degree
arc to the right or left of direct line of sight between the remote control and the switcher
receiver, and from no more than 30 feet (9.1 m) away (see the illustration below).

Enabling Front Panel Lockout (Executive Mode)
Front panel lock mode (executive mode) disables all front panel controls. Putting the
switcher in this mode enhances security by protecting against inappropriate or accidental
changes to settings. When the switcher is in lock mode, RS-232 and IR control remain
available.
To lock or unlock the front panel, press and hold Input buttons 1 and 2 simultaneously for
3 seconds, then release them. The front panel LEDs blink three times, indicating that front
panel lock mode has been enabled or disabled (see the illustration below).

Figure 19. Enabling or Disabling Front Panel Lock Mode
Setting Equalization for Input Sources
The front panel contains a set of Input EQ DIP switches, one for each of the switcher inputs.
High and low equalization levels for each input are selected via these switches. Setting
them to High (up) compensates for a degraded or poor quality signal, reducing the need for
additional signal conditioning equipment.
If the input signal is strong, set the switches to Low (down).
EDID Modes
The SW DVI switchers utilize the EDID Minder, which maintains EDID communication to all
connected source devices, whether or not any of the sources are selected. EDID information
consists of the display resolution, refresh rate, data rate, supported audio formats, and other
features. By factory default, the EDID stored on all inputs contains information for a native
resolution of 1024x768.
The EDID information can be communicated in two modes: automatic and user-assigned.
Automatic mode
In automatic mode, the switcher automatically stores EDID from the connected display and
communicates it to the inputs; no other configuration is required. This is the default mode.
•
Reading and storage process — Each time a display is connected to the DVI output
while the power is connected, the SW DVI Plus reads the EDID from the display device
and stores it at each input. This information is retained after the display is disconnected;
however, it is overwritten if a new display is connected or a user assigned EDID file is
selected.
•
Default EDID — When the switcher is in automatic mode, the default EDID (1024x768
@ 60 Hz) is stored at each input until a display is connected, at which time it is
overwritten.

User-assigned EDID mode
In this mode, you can select an EDID file that is stored on the switcher at the factory.
The selected EDID is stored at the inputs and is not overwritten; the switcher does not
automatically obtain EDID information from the display.
You may want to use this mode if there is a problem with automatic communication of
the EDID information from the attached display, and you want to ensure that the correct
information is stored on the inputs. Also, because this mode disables automatic EDID
reading and storage, you can retain one set of EDID information on the inputs and not have
it changed when another display is connected.
•
Factory-loaded EDID files — You can select from a list of 15 EDID files that are loaded
on the switcher at the factory. Each EDID file contains a unique native resolution. The
table below shows the EDID files that are provided with the switcher.
•
User-loaded EDID file — In addition to the 15 EDID files provided with the switcher, an
empty location (16) is provided, to which you can save the EDID data of the display that
is currently connected to the output port of the switcher. This sixteenth file can then be
selected as one of the available EDID files.
The table below lists the EDIDs that are available to be assigned by the user.

Remote
Configuration and
Control
This section describes remote operation of the SW DVI Plus series. Topics include:
•
•
•
Using Simple Instruction Set (SIS) Commands
The SW DVI Plus can be remotely set up and controlled via a host computer or other device
(such as a control system) that is attached to the rear panel Remote/Auto-SW port. Extron
Simple Instruction Set (SIS) commands are issued from the computer and transmitted to the
information on connecting to this port.)
Host-to-switcher Communications
SIS commands consist of one or more characters per field. No special characters are required
to begin or end a command sequence. Enter these commands on your computer and
send them to the SW DVI Plus using a communication software program such as Extron
DataViewer or HyperTerminal. When the switcher determines that a command is valid, it
executes the command and sends a response back to the host computer.
Most responses from the SW DVI Plus to the host computer end with a carriage return and a
line feed (CR/LF = ]), which signals the end of the response character string. A string is one
or more characters.
Switcher-initiated Messages
When a local event such as a front panel selection takes place, the switcher responds by
sending a message to the host, indicating what selection was entered. No response is
required from the host.
The following switcher-initiated message is sent when the switcher first powers up:
(C)Copyright20nn,ExtronElectronicsSWDVIPlusSeries, Vn.nn, 60-nnn-nn
Vn.nnis the firmware version number; 60-nnn-nnis the part number.
NOTE: This copyright message is displayed only at switcher power-up.

Error Responses
If the switcher is unable to execute a command it receives because the command is invalid
or contains invalid parameters, the switcher returns an error response to the host. Error
response codes and their descriptions are as follows:
E01 – Invalid input channel number (out of range)
E06 – Invalid input selection during auto-input switching
E10 – Invalid command
E13 – Invalid value (out of range)

Mounting the SW DVI Plus Switcher
The SW DVI Plus 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 SW DVI Plus. For tabletop use, attach
one foot at each corner on the bottom of the unit, and place the switcher where desired.
Rack mounting
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.
4. Circuit overloading — When connecting the equipment to the supply circuit, consider
the effect that circuit overloading might have on overcurrent protection and supply
wiring. Consider equipment nameplate ratings 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 (for example, use of power strips).
Rack mounting the SW2 DVI Plus and SW4 DVI Plus
For optional rack mounting of the models with enclosures of 8.75 inches wide by
3 inches deep (two-input and four-input models), use one of the following procedures:
Mounting on a rack shelf
1. If feet were previously attached to the bottom of the unit, remove them.
2. Mount the switcher on the rack shelf, using two 4-40 x 3/16 inch screws in opposite
3. Install blank panels or other units on the rack shelf as desired.
4. Install the shelf in the rack.
