• Features

• Application Diagram

About this Guide

This guide describes the Extron SW HDMI Series switchers and discusses how to install,

configure, and operate them.

In this guide, the term “SW HDMI Series” refers to both the SW2 HDMI and the
SW4 HDMI switchers. “Switcher” and “SW HDMI” are used interchangeably to refer to

any single unit.

About the SW HDMI Series Switchers

The Extron SW HDMI Series are two and four input, one output, High-definition
Multimedia Interface (HDMI) switchers. They allow multiple HDMI signals, including digital

video, 3D signals, and embedded multi-channel digital audio, to be switched to one

compatible display. These switchers support all standard single-link HDMI (up to 225 MHz)
and DVI 1.0 signal formats. They are compatible at 60 Hz with all HDTV resolutions up

to 1080p and PC resolutions up to 1920x1200, with 12-bit color, and are fully compliant

with High-bandwidth Digital Content Protection (HDCP).
The SW HDMI 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.

Features

• HDCP authentication — The SW HDMI switchers check the sources and the display

individually for HDCP compliance. HDCP LEDs for each input and the output indicate
successful HDCP authentication.

• Auto-input switching — The SW HDMI Series can be configured to automatically

switch to the highest-numbered active input when the switcher detects a signal.

• Signal detection LEDs — Each input and the output are represented by front panel

LEDs, which light if a signal is present for the input or output and there is activity on

the Transition Minimized Differential Signaling (TMDS) lines.

• Rack and furniture mounting — The SW HDMI Series can be mounted on a rack

shelf or under a desk or podium with an optional mounting kit.

SW HDMI Series • Introduction 1

• Remote configuration and control — The switcher can be configured via an RS-232

or USB connection via SIS commands (see “Using Simple Instruction Set (SIS)

Commands” in the “Remote Communication and Control” section).

• EDID Minder — A proprietary EDID (Extended Display Identification Data) management

process from Extron, the EDID Minder manages the EDID between a digital display
device and one or more input sources. By maintaining continuous EDID communication
with all sources, EDID Minder ensures that digital sources power up properly and

maintain their video output, whether or not they are actively connected to the digital
display device.

• EDID modes — Either of the following EDID modes can be selected by SIS commands:

• Automatic, in which the SW HDMI 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 46 factory-provided files of EDID

information to each input. Four undefined slots are also provided, to which you can

save the EDID of connected displays as additional EDID files. The assigned EDID does

not change if a different display device is connected. This mode is useful for trouble­shooting purposes.

Each time power is applied to the output device or the display is replaced, the SW HDMI
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).

• Output compatibility correction — The SW HDMI monitors the EDID on the

connected output device to ensure it is compatible with the currently selected input
signal. The following corrections are made to the signal as necessary each time an input
is selected:

• Interface format: If the connected output device is DVI and the selected source is

HDMI, the signal is reformatted for DVI. If the output device is an HDMI device, no
reformatting is necessary because HDMI is backwards compatible with DVI.

• Video color bit depth: If the connected output device does not support the color

bit depth of the selected source signal, it is truncated to the next level down that is

supported; for example, 12-bit >10-bit > 8-bit. Bit depth truncation can be forced

via SIS commands to always downgrade to 8-bit, disabling deep color.

• IR remote control (optional) — The hand-held IR 102 Remote Control can control

the SW HDMI 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, the front panel controls can be locked via the front panel buttons or SIS

commands (RS-232, USB, and IR control remain available).

• Input cable equalization — Automatic input cable equalization compensates for signal

loss when long cable assemblies are used.

• Power supply — An external 12 VDC, 1 A power supply with a 2-pole captive screw

connector accepts 100 to 240 VAC.

d Remote and auto-input switching connector — This 5-pole, 3.5 mm captive

screw connector (labeled “Remote”) can be used for RS-232 communication with the
switcher, including firmware updates, and to enable auto-input switching.

• To enable RS-232 control, connect the Tx (transmit), Rx (receive) and G (ground)

pins to the serial port of your computer (see “Wiring for RS-232 Control” on
page 7).

• 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).

Wiring the Power Connector (Optional)

A 12 VDC, 1 A desktop power supply is provided with the SW HDMI. Should it become
necessary to attach a 2-pole captive screw connector to your Extron power supply, follow

these instructions:

CAUTIONS: • The power supply must not be permanently fixed to the building structure

or similar structures.

• The power supply must not be located within environmental air

handling spaces or the wall cavity.

• The installation must be in accordance with the applicable provisions

of the National Electrical Code ANSI/NFPA 70, Article 725 and the
Canadian Electrical Code, Part 1, Section 16.

• The power supply must be located in the same vicinity as the Extron

AV processing equipment in an ordinary location, Pollution Degree 2,

secured to a podium, a desk, or an equipment rack within a dedicated
closet.

• Always use a power supply specified for the SW HDMI by Extron.

Use of an unauthorized power supply voids all regulatory compliance

certification and may cause damage to the supply and the switcher.

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.

• 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.

3. Slide the leads into the supplied 2-pole captive screw plug and secure them, using a

small screwdriver.

WARNING: The two power cord wires must be kept separate while the power

supply is plugged in. Remove power before wiring.

Enabling Auto-input Switching

You can set up the SW HDMI to automatically select the active, connected input based

on detection of an active video signal. If two or more inputs are active, the input with

the highest number is selected (for example, input 4 on an SW4 HDMI 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.

To enable auto-input switching:

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 above pin slots 4 and

5 of the plug, 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

rear panel.

NOTE: Auto-input switching utilizes the +5 V signal (pin 18 of the HDMI input

connector) to detect an active source (see figure 5 on page 7). This

+5 V signal should be present only when the input source is powered
on. However, some sources may also provide this signal while in standby

mode.

Figure 9 shows an SW4 HDMI with a jumper connecting pins 4 and 5 to enable auto-input

switching.

The input buttons are also used for enabling front panel lockout (executive mode) and
to initiate a system reset (see “Locking and Unlocking the Front Panel (Executive

Mode)” on page 15 and “Resetting” on the next page).

d Signal status LEDs —

• Inputs: Each input has a corresponding numbered Signal LED, which illuminates

when a source is connected to the input connector and TMDS clock activity is
detected on it.

NOTE: If the source device connected to the selected input is HDCP

encrypted (requires HDCP authentication), the corresponding signal
LED may not light unless HDCP has been authenticated.

• Output: The Output Signal LED lights when a TMDS signal is being transmitted to

the connected output device.

e HDCP status LEDs —

• Inputs: Each input has a corresponding numbered HDCP LED. If the connected

source requires HDCP, the corresponding LED illuminates when authentication is

successful.

NOTE: HDCP is pre-authenticated on each input regardless of the currently

selected source.

• Output: The Output HDCP LED lights if the currently selected input requires HDCP

and the connected output device has been successfully authenticated.

NOTE: HDCP is re-authenticated on the output whenever a new input is

selected.

f Config port — Connect a USB cable (USB A to mini B) between your computer and

this female USB mini B port to configure and control the switcher via SIS commands or
the Universal Switcher Control Program and to update the firmware.

Powering on the Switcher

To power on the SW HDMI:

1. Connect all input and output devices to the rear panel connectors on the switcher (see

“Rear Panel Features” on page 5 for the rear panel connections).

2. Power on the display.

3. Plug the power supply into the 2-pole captive screw power connector on the rear

panel. After approximately 4 seconds, the following takes place:

• The unit performs a self-test, during which the front panel Auto Switch, Input,

Signal, and HDCP LEDs each blink once in sequence from left to right. If the
self-test completes with no errors, the LED for the most recently selected input

remains lit.

• The switcher reads the available EDID information from the connected output

device and writes it to memory on each input. When power is removed, these

settings remain in memory and are in effect when power is reapplied.

NOTE: If EDID Minder is in automatic mode, the settings revert to the default

EDID unless a display is connected to the HDMI output (see “EDID

Modes” on page 15).

4. Power on the input devices.

Selecting an Input

To switch (tie) 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.

Other ways to select an input include using SIS commands (see the Input Selection
commands in the “Remote Communication and Control” section) or optional IR remote
control (see “Using the Optional IR 102 Remote Control” on the next page).

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.

SW HDMI Series • Operation 13

Using the Optional IR 102 Remote Control

The optional hand-held IR 102 Remote Control (part #70-224-10) lets you remotely
perform functions that are also available through the front panel buttons and SIS
commands.

The IR receiver port on the front panel is located to the right of the Auto Switch 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 m) away (see figure 12).

Figure 13. Enabling or Disabling Executive Mode

EDID Modes

The SW HDMI switchers utilize the EDID Minder, which maintains EDID communication to
all connected sources, 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 720p @ 60 Hz, 2-channel audio.

EDID Minder can be configured in two modes: automatic and user-assigned.

Automatic EDID 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 HDMI

output while the power is connected, the SW HDMI 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

(720p @ 60 Hz) is stored at each input until a display is connected, at which time it is

overwritten.

SW HDMI Series • Operation 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 46 EDID files that are

loaded on the switcher at the factory. Each EDID file contains a unique native

resolution and audio support (if applicable). The EDID table on the next page shows

the EDID files that are provided with the switcher.

• User-loaded EDID file — In addition to the 46 EDID files provided with the switcher,

four empty locations (47 through 50) are provided. To these slots you can save the

EDID of the display that is currently connected to the output port of the switcher. Any
of these four files can then be selected as one of the user-assigned EDID files.

Changing the EDID mode

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

following SIS command:

E

A * X% EDID }

where X% is 0 (automatic mode) or the number of the user-assigned EDID file that you
want to select (1 through 50) (see the “Remote Communication and Control” section

for instructions for entering SIS commands via RS-232 or USB).

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

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

See the table on the next page for a list of supported EDIDs.

Remote
Communication
and Control

This section describes remote operation of the SW HDMI switchers. Topics include:

• Using Simple Instruction Set (SIS) Commands

• Updating Firmware Using Firmware Loader

Using Simple Instruction Set (SIS) Commands

The SW HDMI can be remotely set up and controlled via Extron SIS commands that are

issued from a host computer or other device, such as a control system. SIS commands can
be issued via RS-232 from the computer serial port to the rear panel Remote port, or via

USB from the computer USB port to the front panel Config port. (See “Wiring for RS-232

Control” on page 7 or “Connecting to the USB Port” on page 8 to connect to these

ports.)

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. You can enter these commands from

your computer 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 to the host device.

Most responses from the SW HDMI 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 or a change in signal status 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 displayed:

(C) Copyright 20nn, Extron Electronics HDMI Switcher Series, Vn.nn,
60-641-nn

The switcher sends the copyright message when it first powers on. Vn.nn is the firmware
version number; 60-641-nn is the switcher part number.

NOTE: This message is displayed only at power-up with an RS-232 connection.

SW HDMI Series • Remote Communication and Control

19

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. The
following error response codes can be sent:

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)

Using the Command and Response Table

The command and response table, starting on page 21, lists valid ASCII and
hexadecimal command codes, the switcher responses to the host, and a description of the
command function or the results of executing the command.

Mounting the SW HDMI

The SW HDMI 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 HDMI. 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 procedures

See the Accessories table on page 30 for the available rack shelf kits and their part
numbers.

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 23 on the next page).

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

4. Install the shelf in the rack.
