About this Guide
This guide describes the SW HD 4K Series switchers and discusses how to install,
configure, and operate them.
In this guide, the terms “SW HD 4K Series” and “SW HD 4K” refer to the SW2 HD 4K and
SW4 HD 4K switchers.
About the SW HD 4K Series Switchers
The SW HD 4K Series are two and four input HDMI switchers for 4K video signals. They
switch 4K signals from multiple HDMI source devices to a single display. The switchers
support computer and video resolutions up to 4K and 1080p/60 with Deep Color, as well
as data rates up to 10.2 Gbps, 3D, Lip Sync, and HD lossless audio formats. All models
feature EDID Minder, which maintains continuous EDID communication with connected
devices and ensures that the HDMI sources power up properly and maintain correct video
output. The switchers provide automatic input cable equalization up to 50 feet (15 meters)
on Extron HDMI Pro Series cable. The SW HD 4K Series offers front panel, RS-232, IR,
contact closure, and auto-input switching control options for integration into various
environments.
The SW HD 4K 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.

• Supports computer and video resolutions up to 4K, including 1080p/60 Deep
Color — Resolutions up to 4096x2160/30 with 4:4:4 chroma sampling at 8 bits
of color.
• EDID Minder automatically manages EDID communication between
connected devices — EDID Minder ensures that all sources power up
properly and reliably output content for display.

SW HD 4K Series • Introduction 2
• Automatic input cable equalization to 50 feet (15 meters) when used with
Extron HDMI Pro Series cable — Actively conditions incoming HDMI signals
to compensate for signal loss when using long HDMI cables, low quality HDMI
cables, and source devices with poor HDMI signal output.
• HDCP compliant — Ensures display of content‑protected media and
interoperability with other HDCP‑compliant devices.
• User‑selectable HDCP authorization — Allows individual inputs to appear
HDCP compliant or non‑HDCP compliant to the connected source, which is
beneficial if the source automatically encrypts all content when connected
to an HDCPcompliant device. Protected material is not passed in non‑HDCP
mode.
• HDCP authentication and signal presence LED indicators
• Automatic color bit depth management — The switcher automatically adjusts
color bit depth based on the display EDID, preventing color compatibility
conflicts between source and display.
• Provides +5 VDC, 250 mA power on the output for external peripheral devices
• Easy setup and commissioning with the Extron Product Configuration
Software — Conveniently configure multiple products using a single software
application.
• Multiple control options including front panel, RS‑232, USB, IR, contact closure,

the corresponding Tally Out pin (T) shorts to ground, activating the connected
indicator (see Wiring the Tally Out Port to Indicate the Input Selection on
page 10 for more information).
E+V connectors — These pins constantly output +5 VDC with 200 mA total (shared
between pins). Use these pins when power is needed for external Tally LEDs, such as
with Extron “Show Me” cables.
FRS‑232 (3‑pole) and auto‑input switching (2‑pole) connector — Use this 3-pole,
3.5 mm captive screw connector for RS-232 communication with the switcher
(including firmware updates) and this 2-pole, 3.5 mm captive screw connector 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
and Auto Switching on page 7).
• To enable auto‑input switching, short the two pins 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 9).
Wiring the Power Connector
A 12 VDC, 1 A power supply is provided with the SW HD 4K. Follow the following
instructions to wire the 2-pole captive screw connector to your power supply:
CAUTION: The wires must be kept separate while the power supply is plugged in.
Remove power before wiring.
ATTENTION : Les deux cordons d’alimentation doivent être tenus à l’écart l’un de

Figure 3. Wiring the Power Connector
ATTENTION:
• Always use a power supply supplied and or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the end product.
• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.
L’utilisation d’une source d’alimentation non autorisée annule toute conformité
réglementaire et peut endommager la source d’alimentation ainsi que le produit
final.
• If not provided with a power supply, this product is intended to be supplied by a
power source marked “Class 2” or “LPS” and rated at 12 VDC and a minimum of
1.0 A.
• Si ce produit ne dispose pas de sa propre source d’alimentation électrique, il doit
être alimenté par une source d’alimentation de classe 2 ou LPS et paramétré à
12 V et 1.0 A minimum.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
• Cette installation doit toujours être en accord avec les mesures qui s’applique
au National Electrical Code ANSI/NFPA70, article725, et au Canadian Electrical
Code, partie1, section16. La source d’alimentation ne devra pas être fixée de
façon permanente à une structure de bâtiment ou à une structure similaire.
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the
power supply and the unit. The ridges on the side of the cord (see figure 3 on the
next page) identify the power cord negative lead.
• La polarité de la source d’alimentation est primordiale. Une polarité incorrecte
pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté du
cordon permettent de repérer le pôle négatif du cordon d’alimentation.
• To verify the polarity before connection, plug in the power supply with no load
and check the output with a voltmeter.
• Pour vérifier la polarité avant la connexion, brancher l’alimentation hors charge et
mesurer sa sortie avec un voltmètre.
• The length of the exposed (stripped) copper wires is important.
The ideal length is 3/16 inch (5 mm). Longer bare wires can short together.
Shorter wires are not as secure in the connectors and could be pulled out.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les
dénuder. La longueur idéale est de 5mm (3/16inches). S’ils sont un peu
plus longs, les câbles exposés pourraient se toucher et provoquer un court
circuit. S’ils sont un peu plus courts, ils pourraient sortir, même s’ils sont attachés
par les vis captives.

SW HD 4K Series • Installation 7
ATTENTION:
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities.
• Sauf mention contraire, les adaptateurs AC/DC ne sont pas appropriés pour une
utilisation dans les espaces d’aération ou dans les cavités murales.
Wiring for RS-232 Control and Auto Switching

Your computer locates the driver needed for it to communicate with the SW HD 4K
via the USB port and loads it to the computer hard drive.
4. When the Completed screen appears, click Finish to close the wizard.
NOTE: This wizard appears only the first time you connect the SW HD 4K to each
USB port. You do not see the wizard again unless you connect the switcher to a
different USB port on your computer.
5. Configure the switcher as desired using SIS commands (see the Remote
Communication and Control section, beginning on page 17 for information on
available commands).
Enabling Auto-Input Switching
The SW HD 4K can automatically select the active, connected input based on detection
of an active video signal (TMDS clock activity). If two or more inputs are active, the
highest-numbered input port with an active signal is selected (for example, input 4 on
an SW4 HD 4K switcher). When auto-input switching is in effect, the green Auto Switch
LED on the front panel lights and the front panel input 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 the Auto slots (slot 4 and 5) of the provided 2-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 figure 4 on page 7).
4. Insert the plug into the 2-pole Auto captive screw connector on the rear panel (see
figures 1 and 2 on page 4).

SW HD 4K Series • Installation 10
The figure to the right shows an SW4 HD 4K with a jumper connecting pins 4
and 5 to enable auto-input switching.
Auto-input switching remains in effect as long as the jumper wire connects the
two Auto pins of the 2-pole captive screw Auto port.
Wiring the Contact Closure Connectors
To enable input switching via contact closure, connect a push-button contact
closure device to a Contact In/Tally Out connector (see figure 4 on page 4).
NOTE: The number of the Contact In/Tally Out port must match the number of the
HDMI In port.
1. Wire and plug one of the provided 3-pole connectors into a Contact In/Tally Out
connector representing the desired input number on the SW HD 4K (1 or 2 for SW2
models; 1, 2, 3, or 4 for SW4 models).
• Pin 1 = Contact closure input (C)
• Pin 2 = Contact and Tally Ground (G)
• Pin 3 = Tally output (T)
2. Insert the ground wire of the contact device into the Ground slot of the Contact/Tally
connector (pin 2).
3. Press the button on the contact closure device to switch the connected input to the
output.
Wiring the Tally Out Port to Indicate the Input Selection
To identify the currently selected input when the front panel buttons are not visible,
connect a device such as an LED to the Contact In/Tally Out connector (see Don
page 4) and +V connector (see Eon page 5). When the input you are using is selected,
the corresponding Tally Out pin shorts to ground, activating the connected indicator.
1. Wire and plug one of the provided 3-pole connectors into a Contact In/Tally Out
connector (see image at right).
• Pin 1 = Contact closure input (C)
• Pin 2 = Contact and Tally Ground (G)
• Pin 3 = Tally output (T)
2. Insert the power wire for the contact indicator device
into the +V connector.

LockIt HDMI Cable Lacing Bracket Installation Guide
The Extron LockIt lacing bracket makes it possible to simply and universally secure a standard
HDMI®cable to most HDMI devices.
NOTE: The HDMI device must have an HDMI connection mounting screw for this
bracket to be used.
To securely fasten an HDMI cable to a device:
1. Plug the HDMI cable into the panel
connection.
2. Loosen the HDMI connection mounting
screw from the panel enough to allow the
LockIt lacing bracket to be placed over it.
The screw does not have to be removed.
3. Place the LockIt lacing bracket on the
screw and against the HDMI connector,
then tighten the screw to secure the
bracket.
ATTENTION:
• Do not overtighten the connector
mounting screw. The shield it
fastens to is very thin and can
easily be stripped.
• Ne serrez pas trop la vis de
montage du connecteur. Le
blindage auquel elle est attachée
est très fin et peut facilement être
dénudé.
4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing
bracket as shown.
5. While holding the connector securely against the lacing bracket, tighten the tie wrap,
then remove any excess length.

selected.
Operations
Powering on the Switcher
To power on the SW HD 4K:
1. Connect all input and output devices to the rear panel connectors on the switcher
(see Rear Panel Features on page 4 for the rear panel connections).
2. Power on the display.
3. Power on the SW HD 4K: Plug the power supply into the 2-pole captive screw
power connector on the switcher rear panel.
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.
ATTENTION:
• Do not connect any external power supplies until you have read the Attention
notifications on page 6.
• Ne branchez pas de sources d’alimentation externes avant d’avoir lu les mises en
garde sur la page 6.
4. Power on the input devices.

SW HD 4K Series • Operation 14
Selecting an Input
To switch 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.
NOTE: Buttons are disabled in auto-switch mode.
• Contact closure — Plug one of the provided 3-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 a Contact In/Tally Out port,
momentarily short one of the Contact Closure pins (C) to the ground pin (G) using
a jumper wire. 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 the Contact Closure Connectors on page 10 for more information.
Other ways to select an input include using SIS commands (see the Input Selection
command on page 20) and optional IR remote control (see Using the Optional IR 102
Remote Control below).
Resetting
To reset the switcher to its factory default settings:
1. Press and hold the Input 1 button while powering on the unit.
2. Continue holding the Input 1 button until the power-up sequence completes.
Using the Optional IR 102 Remote Control
The optional hand-held IR 102 Remote Control 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 the IR receiver sensor, and from no more than 30 feet (9 m) away (see
figure 10 on the next page).

inputs, effectively muting the output.
Locking IR remote access
The SW HD 4K switchers can be set to lock out users from
using the IR 102 to control the switcher. Remote access can
be enabled and disabled via SIS commands (see the Front
Panel IR Receiver Enable and Disable commands on page 22). When remote access
is disabled, all switcher controls remain available through the SW HD 4K 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). Locking the switcher 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
mode has been enabled or disabled (see figure 11).
