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 the SW2, SW4, SW6, and SW8 HDMI
switchers. “Switcher” and “SW HDMI” are used to refer to any single unit.

About the SW HDMI Series Switchers

Features

The SW HDMI Series are two, four, six, and eight input, one output, High-definition
Multimedia Interface (HDMI) switchers. They allow multiple HDMI input signals, including
digital video, 3D signals, and embedded multi-channel digital audio to be switched to
one compatible output display. These switchers support all standard single-link HDMI (up
to 2.25 Gbps) and Digital Video Interface (DVI) 1.0 signal formats. They are compatible
at 60 Hz with all HDTV resolutions up to 1080p and PC resolutions up to 2048x1080,
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, USB,
contact closure, or the optional IR 102 Remote Control. You can select inputs by pressing
the front panel buttons, pressing buttons on the IR 102, enabling auto-input switching,
attaching a jumper or a contact closure device to the Contact port, or entering Simple
Instruction Set (SIS) commands via RS-232 or USB.

• 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.

• Contact closure — The Contact port enables inputs to be selected by contact

closure, with or without a contact closure device.

• Tally output port — Can be used in conjunction with the Contact port to indicate

the selected switcher input.

SW HDMI Series • Introduction 1

• 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.

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

or USB connection via SIS commands (see Remote Communication and Control
beginning on page 21).

• 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 using 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 48 factory-provided EDID files

to each input. Four undefined memory 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 when the display is replaced, the
SW HDMI either reads the EDID information from the display or reloads the user­assigned 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 on
page 17 for more information).

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

connected output device to ensure that 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 depth, 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 —

• SW2 and SW4 HDMI: An energy-efficient, external 12 VDC, 1 A universal power

supply with a 2-pole captive screw connector accepts 100 to 240 VAC.

• SW6 and SW8 HDMI: An 50-60 Hz, internal universal power supply with a

standard IEC connector accepts 100 to 240 VAC.

CAUTION and ATTENTION notices on the next page.

• SW6 and SW8 HDMI: Plug the provided AC power cord into this male IEC

connector and into an AC power outlet.

b Input connectors — Connect HDMI video input sources to these female Type A

single-link HDMI connectors. Data rates of up to 6.75 Gbps are supported.

• LockIt brackets: LockIt cable lacing brackets, one for each HDMI input and the

output connector, are provided with the SW HDMI. These brackets secure the
HDMI cables to the rear panel connectors and reduce stress on the connectors,
preventing signal loss due to loose cable connections. For information on
attaching the LockIt brackets, see the LockIt HDMI Cable Lacing Bracket
Installation Guide, available at www.extron.com.

• EDID information: By default, EDID is read from the output device and written

to switcher memory for each input, allowing each source to see the EDID
information for the output device even when the SW HDMI is switching between
sources.

c Output connector — Connect an HDMI display device to this female Type A HDMI

connector.
The EDID information is read from the connected output device via this connector and
is written to memory on each input whenever the output device is connected to this
port 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.

d Contact port — Plug one of the provided 5-pole captive screw connectors into this

5-pole, 3.5 mm captive screw port. On the SW6 and SW8 HDMI, plug connectors
into either or both parts of the dual Contact port. You can use this port to switch
inputs by:

• Shorting the ground pin to any of the other four pins in the connector (see

Contact Closure under “Selecting an Input” on page 15).

• Connecting a push-button contact closure device to the port (see Wiring for

Input Selection by Contact Closure on page 11).

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

screw connector (labeled “RS-232 Auto”) 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 8).

• 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).

SW HDMI Series • Installation 6

f Tally Out port — (Optional) Plug one of the provided 5-pole captive screw

connectors into this 5-pole captive screw port to indicate which input has been
selected. On the SW6 and SW8 HDMI, plug connectors into either or both parts of
the dual Tally Out port.
Connect an indicator device such as an LED to the attached connector to identify the
currently selected input when the front panel buttons are not visible (see Wiring the

Tally Out Port to Indicate the Input Selection on page 12).

Wiring the Power Connector — SW2 and SW4 HDMI Only (Optional)

A 12 VDC, 1 A power supply is provided with the SW2 and SW4 HDMI. Should it be
necessary to attach a 2-pole captive screw connector to your power supply, follow these
instructions:

CAUTION: Risk of electric shock. The two power cord wires must be kept

separate while the power supply is plugged in. Remove power before wiring.

ATTENTION:

• 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.

ATTENTION:

• 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.

4. To verify the power cord polarity before connecting the plug, connect the power

supply with no load and check the output with a voltmeter.

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. Power on the SW HDMI:

• SW2 and SW4 HDMI: Plug the power supply into the 2-pole captive screw

power connector on the switcher rear panel.

• SW6 and SW8 HDMI: Plug the provided IEC cord into the rear panel IEC

connector and an AC outlet.

After approximately 4 seconds, the following happens:

• 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. When the
self-test completes, 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 port (see EDID

Modes on page 17).

4. Power on the input devices.

Selecting an Input

To switch (tie) an input to the output, you have the following options:

• Front panel buttons: 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.

• The appropriate front panel input LED lights to indicate 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.

• Contact closure: Plug one of the provided 5-pole captive screw connectors into the

rear panel Contact port. Wire either of the following to the port:

• Contact closure device: If a push-button contact closure device is attached to

the Contact port, press the button that is connected to the slot that corresponds
to the desired input.

• Jumper wire: On the connector attached to the Contact port, momentarily short

one of the input pins (1 through 8, depending on your model) to the ground pin
(pin G) using a jumper wire. For example, shorting pin 1 to pin G selects input 1.
Input is switched immediately when the jumper contacts both pins.

NOTE: If an input pin is latched permanently to the ground pin, input

switching by any other method is disabled while those pins are connected.

See Wiring for Input Selection by Contact Closure on page 11 for more
information.

SW HDMI Series • Operation 15

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

(see the Front Panel IR Receiver Enable and Disable commands on page 25). When
remote access is disabled, all switcher controls remain available through the SW HDMI
front panel.

Locking and Unlocking the Front Panel (Executive Mode)

Front panel lock mode disables all front panel controls, locking out users from those
functions (RS-232, USB, and IR control remain available). Putting the switcher in lock
mode enhances security by protecting against inappropriate or accidental changes to
settings. If a front panel button is pressed during lock mode, all front panel LEDs blink
once.

To lock or unlock the front panel, press and hold Input buttons 1 and 2 simultaneously for
3 seconds, then release. The front panel LEDs blink three times, indicating that executive

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 parameters. 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 in memory for 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, 2-channel audio) is stored at each input until a display is connected,
at which time it is overwritten.

SW HDMI Series • Operation 17

User-assigned EDID mode

In this mode, you can select an EDID file that is stored on the switcher. The selected EDID
is stored in memory for the inputs and is not overwritten. The switcher does not 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 48 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 48 EDID files provided with the switcher,

four empty memory locations (50 through 53) are provided. You can use these
memory locations to save the EDID of the display that is currently connected to the
output port of the switcher. Any of these four EDID 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 49 (auto mode) or the number of the user-assigned EDID file that you want to
select (1 through 53) (see the Remote Communication and Control section, beginning
on page 21, 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 8 or Connecting to the USB Port on page 9 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 change
has occurred. No response is required from the host.

The switcher sends the following message when it is first powered on:

(C) Copyright 20nn, Extron Electronics HDMI Switcher Series, Vn.nn,
60-841-nn

20nn

is the year in which the copyright for the firmware was registered, Vn.nn is the

firmware version number, and 60-841-nn is the switcher part number.

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

SW HDMI Series • Remote Communication and Control

21

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 24, lists valid ASCII and

Reference Information

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

The SW2 and SW4 HDMI models can be mounted on a 9.5-inch, 6-inch, or 3.5-inch
deep rack shelf. They can also be mounted vertically to the front or back rack support.
The SW6 and SW8 HDMI models can be mounted directly to the rack using the provided
mounting brackets. For mounting procedures, see the instructions provided with the
mounting option.

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).

Furniture Mounting—SW2 and SW4 HDMI Only

The SW2 and SW4 HDMI switchers can be mounted under a desk, table, or podium
using an under-desk mounting kit (see the mounting instructions provided with the kit).
