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
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.
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.
• 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 2
• 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 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 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.

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.
cOutput 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.
dContact 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

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.

Your computer locates the driver needed for it to communicate with the SW HDMI 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 HDMI 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 21 for information on
available commands).
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 (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 HDMI 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 slots 4 and 5 of the provided 5-pole captive screw
plug, connecting pins 4 and 5 together.

SW HDMI Series • Installation 11
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 12).
4. Insert the plug into the 5-pole Remote captive screw connector on the rear panel.
Figure 12 shows an SW4 HDMI with a jumper connecting pins 4 and 5 to enable
auto-input switching.

Wiring for Input Selection by Contact Closure
The Contact port provides an alternative method of input selection. Connect a
push-button contact closure device to this port to switch the desired input to the output
as follows:
1. Plug one of the provided 5-pole connectors into the Contact port. On the SW6 and
SW8 HDMI, plug connectors into either or both parts of the dual Contact port.
2. Insert the signal wire of the contact closure device into the slot representing the
desired input number on the SW HDMI Contact port.
Pin 1 = Input 1 contact
Pin 2 = Input 2 contact
Pin 3 = Input 3 contact (SW4, SW6, and SW8 HDMI only)
Pin 4 = Input 4 contact (SW4, SW6, and SW8 HDMI only)
Pin 5 (G) = Contact ground
Pin 6 = Input 5 contact (SW6 and SW8 HDMI only)
Pin 7 = Input 6 contact (SW6 and SW8 HDMI only)
Pin 8 = Input 7 contact (SW8 HDMI only)
Pin 9 = Input 8 contact (SW8 HDMI only)
Pin 10 (G) = Contact ground (SW6 and SW8 HDMI only)
3. Insert the ground wire of the contact device into the G slot of the Contact port (pin 5
or 10).
After wiring the connector, press the button on the contact 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, you
can connect an indicator device such as an LED to an input pin and the +V pin of the Tally
Out port. When the input you are using is selected, the corresponding tally out pin shorts
to ground, which activates the connected indicator.
To connect an indicator to the Tally Out port:
1. Plug one of the provided 5-pole
connectors into the Tally Out port. On the
SW6 and SW8 HDMI, plug connectors
into either or both parts of the dual Tally
Out port.
2. Insert the power wire for the contact
indicator device into the +V slot of the
Tally Out connector (pin 5).
3. Insert the ground wire for the indicator into the slot on the Tally Out port that
represents the input that you want to monitor.
Pin 1 = Input 1 tally ground
Pin 2 = Input 2 tally ground
Pin 3 = Input 3 tally ground (SW4, SW6, and SW8 HDMI only)
Pin 4 = Input 4 tally ground (SW4, SW6, and SW8 HDMI only)
Pin 5 = +5 V
Pin 6 = Input 5 tally ground (SW6 and SW8 HDMI only)
Pin 7 = Input 6 tally ground (SW6 and SW8 HDMI only)
Pin 8 = Input 7 tally ground (SW8 HDMI only)
Pin 9 = Input 8 tally ground (SW8 HDMI only)
Pin 10 = +5 V (SW6 and SW8 HDMI only)
Example: One way to use this port is to connect it to a contact closure device with an
LED. Connect the contact device to the Contact port as well. When you use the contact
device to switch the input you are using, the LED lights.
