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 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 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,
pressing buttons on the IR 102, enabling auto-input switching, or entering Simple
Instruction Set (SIS™) commands via RS-232.
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” on page 19).
• 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 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 trouble-shooting 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” on page 15
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 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 — 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 the Extron power supply, follow
these instructions:
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 specied 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.
WARNING: Risk of electric shock. The two power cord wires must be kept separate
while the power supply is plugged in. Remove power before wiring.
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.
