Dear Customer,
Thank you for choosing Lightware UMX4x4-Pro2 matrix switcher. It is able to switch 4
inputs to 4 outputs in a non-blocking crosspoint configuration.
The UMX4x4-Pro2, the all-round universal matrix switcher, is the perfect solution for ever-
changing environments such as small board rooms and classrooms. UMX (Universal
MatriX) technology was developed by Lightware to support various analog and digital
audio visual formats. VGA, YUV, digital DVI, HDMI with HDCP, stereo analog and S/PDIF
digital audio signals are all supported.
2. General description
2.1. Box contents
UMX4x4-Pro2 matrix switcher

LAN UTP crosslink cable, CAT5e type, 3m length
RS-232 straight serial cable (9 pole D-sub Male to Female)
VGA to DVI-D adapter cable (4 pcs.)
User's manual (this document)
2.2. Features
Advanced EDID Management –The user can emulate any EDID on the switcher's
inputs independently, read out and store any attached monitor's EDID
in the internal memory locations, upload and download EDID files
using Lightware Device Controller.
Non-blocking cross point matrix architecture –The router allows any input to be
switched to any output or more outputs simultaneously.
2.25 Gb/s channel transmission –Routes any DVI single link or HDMI signal between
25 and 225 MHz pixel clock frequency conforming to DVI 1.0 and
HDMI1.3 standards.
Supports all HDTV resolutions –720p, 1080i, 1080p 2K etc. HDTV signals up to 225
MHz pixel clock frequency regardless of the actual resolution passed
through the router.
Control by front panel buttons –4 source select, 4 destination select, Video layer,
Audio layer, Take, Load preset, Save preset, EDID function, Signal
present, Control Lock, Output Lock.
Reconfigurable buttons –Each button has a removable flat cap and a translucent label
that can be inserted under the cap to identify sources and
destinations.
RS-232 control –Simple ASCII based RS-232 protocol is used for switching, preset
calling, status request, etc.
Ethernet control –TCP/IP Ethernet 10Base-T or 100Base-TX (Auto- Sensing).
Built-in WEB site –Easy access from a WEB browser to control and configure the
switcher.

Page 10 / 136 Section 2. General description
Universal power supply –UMX4x4-Pro2 matrices accept AC voltages from 100 to 240
Volts with 50 or 60 Hz line frequency on standard IEC connector.
Power failure memory –In case of power failure, the unit stores its latest configuration,
and after next power up it loads automatically.
HDCP compliant –UMX4x4-Pro2 matrices comply with HDCP1.2 standard. Lightware is
a legal HDCP adopter. The included Advanced HDCP Management
eliminates the need for re-authentication upon switching.
20 meter input cable compensation –Using 22AWG high quality DVI or HDMI cable,
the inputs are automatically compensated for up to 20 meter cable
length, which extends installation possibilities even at the highest
HDTV or computer resolutions.
Pixel Accurate Reclocking –(removes jitter caused by long cables) Each output has a
clean, jitter free signal, eliminating signal instability and distortion
caused by long cables or connector reflections.
Frame detector and signal analysis –Using the built-in webpage or Lightware Device
Controller (LDC) software the user can monitor incoming signal
parameters such as resolution, signal timing parameters, audio type,
scan rate, HDCP encryption and so on.
DVI/HDMI conversion –The router is able to convert from HDMI to DVI signals so that
you can watch HDMI videos on your computer display without audio.
Fiber cable support –Self powered DVI fiber cables using +5V from DVI sources (VGA
cards, etc.) usually consume more than 50 mA, which load is
maximum allowed by DVI 1.0 standard. UMX4x4-Pro2 supports +5V
500 mA constant current output on each DVI output to power long
distance fiber optical cables.
Zero frame delay –Even on Analog Inputs - Lightware’s UMX4x4-Pro2 matrix
switchers add no frame delay to the switched signal. There is no
frame or line period delays to the signals when passing a Lightware
router.
Separate Audio and Video matrix switching –Video and audio signals can be
separated and switched independently. Even if the HDMI stream
contains embedded audio.
Analog Audio and Video A/D conversion –UMX4x4-Pro2 matrices convert
uncompressed analog audio and video signal to digital and the digital
or digitized analog audio can be embedded in the video stream.
Accepts analog and digital audio signals –UMX4x4-Pro2 accepts unbalanced analog
stereo; 5.1 S/PDIF and even 7.1 HDMI embedded audio signals.

Figure 3-3. UMX4x4-Pro2 port diagram
Input side:
The DVI-I connector accepts analog (VGA, YUV) or digital (DVI, HDMI) video
signals.
Analog video is always digitalized by the A/D converter of the input port.
The embedded audio is always unwrapped from the HDMI signal by the
de-embedder of the input port.
Analog audio is always digitalized by the A/D converter of the input port.
The input port properties (2/1 video and 3/1 audio switch) determinate which
video (digitalized analog or digital) and which audio (digitalized analog, S/PDIF or
unwrapped) signal reaches the crosspoint.
Output side:
The embedder of the output port wrap the selected audio (selecting by the digital
audio crosspoint) into the HDMI stream.
If the video output is forced to DVI mode, there is no embedded audio.
S/PDIF gives out the selected audio up-to two channels of uncompressed PCM
audio or compressed 5.1/7.1 surround sound (such as DTS audio codec).
(Dolby TrueHD and DTS-HD Master Audio bandwidth needs exceed the standard
S/PDIF capability.)
Analog audio output gives the first two channels of the selected audio, if it is not
compressed (e.g. LPCM).

1- These pins are connected only on the DVI inputs.
DVI outputs
29 pole DVI-I connectors for outputs have only digital pins internally connected. This way,
users can plug in any DVI connector, but keep in mind that analog signals (such as VGA
or RGBHV) are NOT available on the outputs.
Fiber Cable powering
DVI outputs are able to supply 500 mA current on DDC +5V output (pin 14 on output
connectors) which is sufficient to supply power to fiber optical DVI cables. Standard DVI
outputs usually supply only 55 mA current on +5V output, thus unable to directly power a
fiber optical cable.
Info: The matrix switcher does not check if the connected sink (monitor, projector or other
equipment) supports Hotplug or EDID signals but outputs the selected signal immediately
after switch command.

4.1. Basics
EDID stands for Extended Display Identification Data. Simply put, EDID is the passport of
display devices (monitors, TV sets, projectors). It contains information about the display’s
capabilities, such as supported resolutions, refresh rates (these are called Detailed
Timings), the type and manufacturer of the display device, etc.
After connecting a DVI source to a DVI display, the source reads out the EDID to
determine the resolution and refresh rate of the image to be transmitted.
Figure 4-1. EDID communication
Most DVI computer displays have 128-byte long EDID structure. However, Digital
Televisions and HDMI capable displays may have another 128 bytes, which is called E-
EDID and the most common extension is defined by CEA (Consumer Electronics
Association). This extension contains information about additional Detailed Timings,
audio capabilities, speaker allocation and HDMI capabilities. It is important to know, that
all HDMI capable devices must have CEA extension, but not all devices are HDMI
capable which have the extension.
4.1.1. Common problems related to EDID
Problem: „My system consists of the following: a computer, a Lightware UMX4x4-Pro2
matrix, a WUXGA (1920x1200) LCD monitor, and an SXGA (1280x1024)
projector. I would like to see the same image on the monitors and the
projector. What EDID should I chose on the monitor and the projector?”
Solution: If you want to see the image on both displays, you need to select the
resolution of the smallest display (in this case SXGA), otherwise the smaller
display may not show the higher resolution image.

Page 20 / 136 Section 4. Technologies
Problem: „I have changed to a different EDID on an input port of the matrix to have a
different resolution but nothing happens.”
Solution: Some graphics cards and video sources read out the EDID only after power-
up and later they don’t sense that EDID has been changed. You need to
restart your source to make it read out the EDID again.
Problem: „I have a UMX4x4-Pro2 and I’m using a Lightware factory preset EDID. I
would like to be able to choose from different resolutions, but my source
allows only one resolution.”
Solution: Most of the Lightware factory preset EDIDs allow only one resolution, forcing
the sources to output only that particular signal. You need to select a
Universal EDID. It supports all common VESA resolutions. Additionally it
also features audio support.
4.2. Advanced EDID management
Each DVI sink (e.g. monitors, projectors, plasma displays, and switcher inputs) must
support the EDID data structure. Source BIOS and operating systems are likely to query
the sink using DDC2B protocol to determine what pixel formats and interface are
supported. HDMI standard makes use of EDID data structure for the identification of the
monitor type and capabilities. Most DVI sources (VGA cards, set top boxes, etc.) will
output DVI signal after accepting the connected sink’s EDID information. In case of EDID
readout failure or missing EDID the source will not output DVI video signal. UMX4x4-Pro2
provides Lightware’s Advanced EDID Management function that helps system
integration. The built in EDID memory stores and emulates pre-programmed factory
EDIDs, user’s EDIDs and all monitor's EDID that is connected to the output connectors.
The router stores the EDID of all attached monitors or projectors for each output in a
non-volatile memory. This way the EDID from a monitor is available when the monitor is
unplugged, or switched off.
Any EDID can be emulated on any input. An emulated EDID can be copied from the
EDID router's memory (static EDID emulation), or from the last attached monitors
memory (dynamic EDID emulation). For example, the router can be set up to emulate a
device, which is connected to one of the outputs. In this case the EDID automatically
changes, if the monitor is replaced with another display device (as long as it has a valid
EDID).
EDID is independently programmable for all inputs without affecting each other. All inputs
have their own EDID circuit. EDID management can be controlled via serial port or
Ethernet.
Info: The user is not required to disconnect the DVI cable to change an EDID as opposed to
other manufacturer’s products. EDID can be changed even if a source is connected to the
input and it is powered ON.
Info: When EDID has been changed, the router toggles the HOTPLUG signal for 2 seconds.
Some sources do not observe this signal, so in this case the change is not recognized by
the source. In such cases the source device must be restarted or powered OFF and ON
again.
