SMX System MultiMatrix Switcher • Introduction 4
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.
