• Application Diagrams

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 congured 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 Identication 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 congure 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.

SW DVI Plus Series • Installation 7

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.

All Other Models (Remote/Auto-SW Connector)

On all models except the non-audio SW2 and SW4 DVI Plus, the 5-pole, 3.5 mm
Remote/Auto-SW captive screw connector is used for optional RS-232 communication and to

enable auto-input switching between inputs connected to the switcher.

Use a female 9-pin D-to-bare wire RS-232 cable or a universal control cable (UC50', UC100',
or UC200') to connect your computer or control system to the RS-232/Auto-SW connector.

1. Wire the unterminated end of the RS-232 cable to the provided 5-pole captive screw

plug as described below. Connect the transmit, receive, and ground wires of the cable to
the first three pins on the connector, starting at the left:

• Connect the transmit wire to pin 1, which plugs into the Tx (transmit) port.

• Connect the receive wire to pin 2, which plugs into the Rx (receive) port.

• Connect the ground wire to pin 3, which plugs into the

_

(ground) port.

2. Plug the 5-pole connector into the Remote/Auto-SW receptacle on the rear panel.

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

the following SIS commands (see the “Remote Configuration and Control” section,
beginning on page 18, for information on using SIS commands).

• 1# selects normal switch mode.

• 2# selects auto-input switch mode.

Operations

a Auto Switch Active LED — This LED lights when auto-input switching is enabled. (See

“Enabling Auto-input Switching” in the “Installation” section for the procedure to
set up auto-input switching.)

b IR receiver port — This sensor detects IR signals from the optional IR 102 remote

control (see “Using the Optional IR 102 Remote Control” on page 14 for more
information).

c Input Selection buttons and LEDs — Press these buttons to select inputs 1 through

2, 4, 6, or 8, depending on your model. The LED at the right of each button lights when

the corresponding input is selected. (These buttons are disabled if auto-input switching

is in effect; however, the LEDs continue to light to indicate the selected input.)

d Input EQ DIP switches — These DIP switches (one for each input) set the equalization

for the corresponding input (see “Setting Equalization for Input Sources” on
page 15 for more information).

e Signal Presence LEDs — Each of these LEDs lights when a signal is present on the

corresponding input.

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

“Rear Panel Features” in the “Installation” section for information on the rear panel
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.

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 conguration, 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

for the selected input blinks (see the “Select audio input only” command in the
Command and Response Table for SIS commands,”Remote Configuration and Control”
section).

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.

SW DVI Plus Series • Operation 13 13

Other ways to select an input include using SIS commands (see the Input Selection

IR 102 Remote Control

commands in the Command and Response Table for SIS Commands, “Remote

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).

or 3 seconds.

LEDs blink 3 times.

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 le 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.

SW DVI Plus Series • Operation 15 15

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 les that are loaded

on the switcher at the factory. Each EDID le contains a unique native resolution. The
table below shows the EDID les that are provided with the switcher.

• User-loaded EDID file — In addition to the 15 EDID les 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 les.

The table below lists the EDIDs that are available to be assigned by the user.

Changing the EDID mode

EDID modes can be switched only by SIS command. By default, the SW DVI Plus is in
automatic EDID mode. To change between automatic and user-assigned modes, enter the

following SIS command:

E

where X% is 0 (automatic mode) or the number of the EDID file that you want to select
(1 through 16). (See the “Remote Configuration and Control” section, beginning on
page 18, for instructions for entering SIS commands via RS-232.)

NOTE: The switcher remains in the selected EDID mode after power is recycled. If the

A * X% EDID }

unit is reset to factory defaults, it reverts to automatic mode.

SW DVI Plus Series • Operation 16 16

Resetting

To reset the switcher to its factory default settings:

1. Press and hold the Input 1 button while power is being applied to the unit.

2. Continue holding the Input 1 button until the power-up sequence completes.

NOTE: Resetting restores the EDID mode to automatic, with a resolution of

1024x768 @ 60 Hz. If a display is connected at the time of the reset, its EDID

information is detected and stored at the inputs.

SW DVI Plus Series • Operation 17 17

Remote Configuration and Control

This section describes remote operation of the SW DVI Plus series. Topics include:

• Using Simple Instruction Set (SIS) Commands

• Universal Switcher Control Program

• Updating Firmware Using Firmware Loader

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
SW DVI Plus via RS-232. (See “Wiring for RS-232 Control” in the “Installation” section for
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) Copyright 20nn, Extron Electronics SW DVI Plus Series, Vn.nn, 60-nnn-nn
Vn.nn is the firmware version number; 60-nnn-nn is the part number.

NOTE: This copyright message is displayed only at switcher power-up.

SW DVI Plus Series • Remote Configuration and Control 1818

Error Responses

Space

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) specied 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

(diagonal) corners to secure the unit to the shelf (see figure 34 on the next page).

3. Install blank panels or other units on the rack shelf as desired.

4. Install the shelf in the rack.
