The 2U frame has 4 single board slots, the 3U frame has 6 board slots, the 4U frame has
8 slots, and the 5U frame has 10 slots. Each slot supports power and control connections
to the I/O boards. When a board is installed into a slot it may use more than one slot. For
example, the SMX 1616 VGA board uses four slots. The slots that a board covers are not
available for other I/O board installation until that multi-slot board has been removed (see
Installing the I/O Boards on page 10 for details).
NOTE: To customize the SMX unit, use the SMX Configurator program, available at
www.extron.com, or contact Extron Customer Support (see back cover for contact
numbers).
SMX System MultiMatrix Switcher • Introduction 2
Definitions
The following terms are used throughout this guide:
Tie — An input-to-output connection
Set of ties — An input tied to two or more outputs. An output can never be tied to more
than one input
Configuration — One or more ties or one or more sets of ties
Current configuration — The configuration that is currently active in the switcher (also
called configuration 0)
Plane — A board or set of boards that will be switched together. Plane numbers are set by
a rotary switch on each board.
Global memory preset — An I/O configuration that has been stored (all planes). Up to 32
global memory presets can be stored. Preset locations are assigned to the input buttons
and output buttons and can be selected from the front panel, serial port, or Ethernet control
for either saving or retrieving. When a preset is recalled from memory, it becomes the
current configuration.
Plane memory preset — A plane configuration that has been stored. Up to 10 plane
presets per switching plane can be saved and recalled without affecting the other I/O plane
connections.
EDID — Extended Display Identification Data. A communications protocol or instruction set
developed by VESA (Video Electronics Standards Association) for the identification of display
devices to computers using the DDC (Display Data Channel) transmission standard
HDCP — High-bandwidth Digital Content Protection. An encryption method developed
®
by Intel
that protects copyrighted digital entertainment material that uses the Digital Video
Interface (DVI) and High Definition Multimedia Interface (HDMI)
DVI — Digital Visual Interface. The digital video connectivity standard developed by DDWG
(Digital Display Work Group). This connection standard offers two different connectors:
one with 24 pins that handles digital video signals only, and one with 29 pins that handles
both digital and analog video. DVI standard uses TDMS (Transition Minimized Differential
Signal) from Silicon Image and DDC (Display Data Channel) from VESA (Video Electronics
Standards Association). DVI-D supports digital signal transfer only, and DVI-I supports both
digital and analog signal transfer.
HDMI® — High Definition Multimedia Interface. A specification developed by the HDMI
Working Group that combines video, multi-channel audio, and control signals into a single
digital interface for use with DVD players, digital television, and other audiovisual devices
SDI — Serial Digital Interface. This standard is based on a 270 Mbps transfer rate. It is a
10-bit, scrambled, polarity independent interface with common scrambling for both
component ITU-R 601 and composite digital video and four channels of embedded digital
audio.
HD-SDI — High-definition version of SDI specified in SMPTE-292M. This standard
transmits audio and video over a single coaxial cable with a data rate of 1.485 Gbit/second.
USB — Universal Serial Bus. Developed by PC and telecom industry leaders, USB was
designed for easy plug-and-play expansion outside the device, requiring no additional circuit
cards. USB devices can be attached or detached without removing computer power.
SMX System MultiMatrix Switcher • Introduction 3
Features
Hot swappable input/output boards and SFP modules — Any board or SFP module
can be added or replaced without taking the unit out of service or removing the power.
Channel to channel isolation — Each I/O board provides isolation between channels and
extremely low electrostatic emissions.
Quick-Switch Front Panel Controller (QS-FPC™) — The QuickSwitch FPC allows for
touch-of-a-button input and output selection and switching.
Presets — This time-saving feature allows the setup and recall of recurring I/O
configurations using either the front panel, RS-232 or RS-422, or Ethernet.
Global: Up to 32 individual I/O configurations may be saved and recalled.
Plane: Up to 10 presets per switching plane can be saved and recalled without
affecting the other I/O plane connections.
RS-232 and RS-422 control — A rear panel RS-232/RS-422 control port provides
connection to control software via a control system or PC.
Front panel control configuration port — A front panel 2.5 mm mini jack is available
for setup and configuration the SMX without having to access the rear of the unit while it is
installed within a rack system.
Simple Instruction Set (SIS) — The remote control protocol uses SIS commands for easy
programming and operation.
Control and configuration software — For RS-232, RS-422, and Ethernet control from
a PC, the Extron control software that runs on Windows operation systems is supplied with
every matrix switcher. This icon-driven software uses a graphical, drag-and-drop interface
to make input and output configuration and other customization functions simple and
convenient. The software also offers an emulation mode for configuration of an off-site
matrix switcher; the input and output configuration can then be saved for future
downloading to the SMX.
IP control (Ethernet) via the LAN port — This port allows the switcher to be controlled
through an Ethernet local area network (LAN) or wide area network (WAN) using standard IP
internet protocols. This ability provides flexible connectivity for off-site control and
password-protection of the switcher.
Web hosting — Users can upload customized web pages into the switcher.
™
Digital Sync Validation Processing (DSVP
) — In critical environments or unmanned,
remote locations, it may be vital to know that sources are active and switching. Extron
DSVP confirms that input sources are active by scanning all sync inputs for active signals.
DSVP provides instant frequency feedback for composite sync or separate horizontal
and vertical sync signals via the RS232/RS422 port or the Ethernet port.
Virtual plane grouping — Switching planes can be grouped together to make a single,
virtual switching plane. Plane grouping allows several signal planes to act as a single unit
with a single control command affecting all planes
Audio input gain and attenuation — Users can set the input level of audio gain or
attenuation (-18 dB to +24 dB) via the RS232/RS422 port, an Ethernet link, or the front
panel. Individual input audio levels can be adjusted so there are no noticeable volume
differences between sources.
Audio output volume (audio I/O boards) — The audio volume of each output can be
displayed and adjusted through a range from full output to completely silent using the front
panel, or through serial port or Ethernet control.
RGB delay (VGA and RGBHV) — This allows the delay of the output of the signal by a
specified time (the delay time), enabling video and audio signals to be kept in sync. RGB
delay can be set via the front panel, RS-232 or RS-422, or LAN connection.
SMX System MultiMatrix Switcher • Introduction 4
Three front panel security lockout modes (executive modes) — If a matrix switcher is
installed in an area where operation by unauthorized personnel may be a problem, either of
two security lockout modes can be implemented (the third mode is unlocked). When a front
panel locked mode is enabled, a special button combination or SIS command is required to
unlock the front panel controller and make the front panel operational.
Upgradeable firmware — The firmware that controls all switcher operation can be
upgraded on location through the serial port or the Ethernet port, without taking the
switcher out of service. Firmware upgrades are available for download on the Extron
website, www.extron.com, and they can be installed using the Windows-based control
program or the built-in HTML pages.
Button labeling — The Extron button label software lets you create labels to place in
the front panel I/O buttons, with names, alphanumeric characters, or color bitmaps.
Alternatively, labels can be made with any Brother® P-Touch® or comparable labeler.
Operational flexibility — Operations such as input and output selection, setting of
presets, and adjustment of audio levels can be performed on the front panel or via the
Ethernet or serial link. The serial links allow remote control via a PC or control system. The
Ethernet link allows multiple remote links with two levels of password-protection.
• Front panel controls — The front panel controls support input and output selection
and grouping, preset creation and selection, RGB delay, audio gain and attenuation,
and volume control (audio models).
• Windows-based control program — Via serial port or Ethernet remote control, the
Windows-based control software provides a graphical interface and drag-and-drop or
point-and-click operation.
• Simple Instruction Set (SIS) — SIS commands provides easy programming and
operation.
Switching flexibility — The SMX provides individually buffered, independent matrix
switched outputs with audio follow and audio breakaway for audio models:
• Tie any input to any or all outputs
• Quick multiple tie — Multiple inputs can be switched to multiple outputs
simultaneously. This allows all displays (outputs) to change from source to source at the
same time.
• Audio follow — Audio can be switched with its corresponding video input via front
panel control, under Ethernet, RS-232 or RS-422 control, or by giving the video and
audio boards the same plane address.
• Audio breakaway — Audio can be broken away from its corresponding video signal.
This feature allows any audio signal to be selected with any video signal simultaneously
to one or all outputs in any combination. Audio breakaway switching can be done via
Ethernet, RS-232 or RS-422 control, or by giving the video and audio boards different
plane addresses.

transmission as the devices communicate.
NOTE: Do not use standard telephone cables, as they do not support Ethernet or fast
Ethernet. Do not stretch or bend cables. Transmission errors can occur.
Choosing a network cable
Ethernet links use Category (CAT) 3, 4, 5, 5e, 6, or CAT 7 unshielded twisted pair (UTP) or
shielded twisted pair (STP) cables, terminated with RJ-45 connectors. Ethernet cables are
limited to 328 feet (100 m).
The cable used depends on the network speed. The SMX supports both 10 Mbps
(10Base-T — Ethernet) and 100 Mbps (100Base-T — fast Ethernet), half-duplex and
full-duplex, Ethernet connections.
• 10Base-T Ethernet requires, at a minimum, CAT 3 UTP or STP cable.
• 100Base-T fast Ethernet requires, at minimum, CAT 5 UTP or STP cable.

Connect audio devices, such as an audio amplifier or powered speakers to the eight
sets of 3.5 mm, 5-pole captive screw connectors marked “Outputs.” The connectors
output the selected unamplified, line level audio (see Wiring the Audio Connectors on
page 12 to properly wire an output connector).
By default, audio and video use different boards, so that audio breakaway is switched
separately. This is done via the front panel, Ethernet, or the RS-232 or RS-422 link,
allowing selection from any of the audio input sources (see Operation on page 13,
SIS Configuration and Control on page 34, SMX Control Software on page 59, or

SMX 84 USB
Connect host devices (such as a PC) to any of the USB Type B Hosts ports (inputs).
Connect suitable USB devices (such as a mouse or keyboard) to any of the USB Type A
Device Hubs ports (outputs).
NOTES:
• There are 3 USB hubs in series within the USB boards. Per USB specifications, up to
• USB boards cannot be cascaded.
• Appropriate USB Type A to USB Type B cables or adapters may be required for USB
Features of SMX USB boards:
Peripheral emulation — Constantly emulates an HID (Human Interface Device) compliant
mouse and keyboard to any connected host without necessitating any ties to an output
device. This feature facilitates a problem-free boot up and is evident in the device manager
of the host PC as it constantly reports a mouse and keyboard are connected to it.
Host emulation — Emulates a host to multiple standard keyboards and mice. Connected
keyboards and mice operate as one unit.
The default setting for host emulation is Off. To enable or disable host emulation (see the
USB Board SIS commands on page 52 or USB Settings/Status on page 67).
5 USB hubs can be used in a system.

NOTES:
• When host emulation is enabled, Device Hubs ports continually provide power to
attached peripherals. However, they will not function until ties are made to a host.
• Host emulation is valid through a hub or USB extender.
• If non-HID devices are connected to the Device Hubs ports, host emulation is
disabled.
Hot key switching — Routes or makes a tie between a specific input using a specific
combination of key presses on an attached keyboard and an output. To make a tie, press
<Ctrl> + <Shift> + <desired input to be tied>.
NOTES: Hot key switching can be executed only under the following conditions:
• Host emulation is enabled for the desired output.
• The output has a “standard” keyboard (it cannot require special USB drivers) to
execute the button combination for hot key switching.
KVM application — The USB and video board must be set to the same plane address in
order to switch the keyboard, video, and mouse together during ties.
SMX Frame and I/O Board Installation
If the SMX is to be rack mounted, it is important to mount it before cabling it (see Mounting
the Switcher on page 115).
Installing the I/O Boards
The I/O boards on any unit may vary with each installation, depending on desired
configuration and use. Each board has input and output connectors that are clearly marked,
and a 16-position rotary switch used to set the I/O plane address.
SMX System MultiMatrix Switcher • Installation and Cabling 10
NOTES:
• The boards are hot-swappable: they can be installed or removed without turning
off or disconnecting the power. However, turning the power off prior to installing or
removing boards is recommended.
• Use ESD precautions when installing a board to avoid damaging it. Keep the
board in the anti-static bag until needed. Use proper grounding techniques during
installation.
See Frames and I/O Boards on page 114 for a full list of available boards for the SMX.
Installing new boards into an empty SMX frame
1. Remove as many of the blanks plates from the rear of the unit as needed.
2. When ready, remove the board from the anti-static bag, taking care not to touch any
of the components on the board. Slide the board into the open rear slot (see figure 4),
carefully aligning it with the plastic slides in the frame. Push the board firmly into place.

the change or recalls the preset, and the Enter button and any lit input and output
buttons extinguish (see Front Panel Operation on page 16).
Preset button — The Preset button gives access to recall or save up to 32 global
presets (using I/O buttons 1 through 16), and 10 plane presets (using input buttons 1
through 10). The button lights red when pressed. Upon recalling or saving the preset,
the button and all input and output buttons (lit red) are extinguished (see Front Panel
Operation on page 16 and Saving and Recalling I/O Presets on page 22).
NOTE: Global presets save and recall the configuration for all planes. Plane presets
save and recall the configurations for a specific plane without affecting the other
plane connections.
View (<) button — This button, when pressed and released, lights red and allows
quick viewing of existing input and output ties. When the button is lit, after selecting
a plane and an associated input, muted outputs flash and untied outputs light the
appropriate signal color (red, green, or amber). Tied outputs remain unlit.
NOTE: Use this button to decrease settings for RGB delay, input audio level, and
output audio volume. This button also mutes and unmutes outputs (see Muting or

Powering Up
When power is applied to the SMX, it undergoes a start-up self testing sequence:
1. All buttons flash green, red, and then amber, before extinguishing.
NOTE: The order in which the colors are displayed may vary.
2. The two LEDs light green to indicate power is present to the main unit and I/O boards.
NOTE: This sequence also occurs when the unit restarts after firmware uploads.
Front Panel Operation
This section covers basic setup and configuration of the SMX using the front panel.
Ties — General Information
• During any operation of front panel buttons, any active input, output, and control
buttons stay lit or blink for 30 seconds. If, during that 30 seconds, no button is pressed,
a time-out occurs and all buttons go out. The operation must be restarted.
• To enable any selected input signal to be viewed on a display device, the input must be
tied to an output on the same plane.
• An output can be tied to one input only, but an input can have multiple outputs.
• If an input with no existing tie is selected, only that input button lights when pressed. No
output buttons light.
• When a plane and an input are selected, the associated output buttons flash the
appropriate color to indicate tentative ties. Buttons for outputs to the selected input light
steadily in the appropriate color.
• If a tie is made between an input and an output and the selected output was previously
tied to another input, the older tie is broken when the Enter button is pressed.

NOTE: A global preset saves and recalls configurations for all planes. A plane preset
saves and recalls the configurations for a specific plane without affecting the other plane
connections.
Each global preset can be saved and recalled using the front panel input and output
buttons, with presets 1 through 16 assigned to the input buttons and presets 17 through 32
assigned to the output buttons. Likewise, plane presets are saved to and recalled from input
buttons 1 through 10. Any current tie configuration can be saved to any one of the preset
locations, in any order. Saving the current configuration to an existing preset overwrites the
existing preset with the new configuration.
