2. Installation
2.1. Mounting Options
The matrix can be mounted in several ways by the supplied two rack ears. Allen head
screws fix them to the housing:
WARNING!
M4x8 size is the longest allowed screw for xing the ears to the housing. A longer
screw may touch internal parts.
Standard Rack Installation (Default)
Two rack ears are supplied with the product,
which are fixed on left and right side as
shown in the picture. The default position
allows mounting the device as a standard
rack unit installation.
Mounting with Front and Rear Rack Ears
ATTENTION!
Two rack ears are assembled on the matrix as default, thus, you will need two more rack
ears for this kind of installation, which can be purchased separately.
The matrix can be easily mounted under the desk by rack ears. This mounting option
means the top of the matrix is parallel with the base surface. Please do the following steps:
Step 1. Release and remove the xing screws of the rack ears on the matrix (both sides).
Step 2. Rotate the rack ears by 90° to the
desired direction.
Step 3. Insert the screws into the holes and
x the front ears to the matrix.
Step 4. Fix the two additional rear ears (not
supplied with the product) by the
screws on both sides of the matrix.
Step 5. Fix the matrix through the holes of
the rack ears to the desired surface
(screws are not supplied).
INFO
The method is the same when the matrix would be mounted to a wall.

2.3. Audio Cable Wiring Guide
Inputs and outputs of audio devices are usually symmetric or asymmetric. The main
advantage of the symmetric lines is the better protection against the noise, therefore it is
used widely in the professional audio industry. Symmetric audio is most often referred to
as balanced audio, as opposed to asymmetric, which is referred to as unbalanced audio.
Ligthware products are usually built with 5-pole Phoenix connectors so we would like to
help users assembling their own audio cables. See the most common cases below.
See more information about the Analog Audio ports in section 3.3 on page 16.
ATTENTION!
Symmetric and asymmetric lines can be linked with passive accessories (e.g. special
cables), but in this case, the half of the line level can be lost.
ATTENTION!
There are numerous types of regularly used connector and cable types to connect audio
devices. Please always make sure the desired cable types and connectors will t well to
your system.

3.3. Electrical Connections
HDMI Input and Output Ports
The matrix switchers are assembled with standard 19-pole HDMI
connectors for inputs and outputs. The outputs are able to supply 500 mA
current on DDC +5V output (pin 18) which is sufficient to supply power to
certain devices (e.g. DA2-HDMI-4K-Plus-A).
Symmetrical Analog Stereo Audio
5-pole Phoenix connector is used for balanced analog audio (line in/out). Some I/O boards
use this connector as a configurable input or output. Unbalanced audio signals can be
connected as well. For asymmetrical output, connect only + and ground. For asymmetrical
input connect + and ground to the source and connect – to the ground.

4. Technologies
4.1. EDID Management
4.1.1. Understanding the EDID
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.
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 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.
Common Problems Related to EDID
Problem: My system consists of the following: a computer, a Lightware matrix, a WUXGA
(1920x1200) LCD monitor, and an SXGA (1280x1024) projector. I would like
to see the same image on the monitor and the projector. What EDID should I
chose on the router?”
Solution: If you want to see the image on both displays, you need to select the resolution
of the smaller display (in this case SXGA), otherwise the smaller display may
not show the higher resolution image.
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 do not sense that EDID has been changed. You need to restart
your source to make it read out the EDID again.
Who are
you? I am a monitor.
Here is my EDID.
Now I know what
I can send.

User’s Manual
Chapter 4. Technologies Page 17 / 88

4.1.2. Advanced EDID Management
Each DVI sink (e.g. monitors, projectors, plasma displays, etc...) 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. DVI 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 the case of EDID readout failure or missing EDID,
the source will not output DVI video signal.
The matrix switchers provide Lightware’s Advanced EDID Management function that
helps system integration. The built-in EDID Router can store and emulate factory pre-
programmed- and User programmable EDIDs. 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 monitor's 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 input
has its own EDID circuit. EDID Router 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 powered ON.
INFO
When EDID has been changed, the router toggles the HOTPLUG signal for 2 seconds.
Some sources do not observe this signal. In such cases, the source device must be
restarted or powered OFF and ON again.
4.2. HDCP Management
Lightware Visual Engineering is a legal HDCP adopter. Several functions have been
developed which help to solve HDCP related problems. Complex AV systems often have
both HDCP and non-HDCP components. The matrix allows transmitting HDCP encrypted
and unencrypted signals. The devices will be still HDCP compliant as they will never output
an encrypted signal to a non-HDCP compliant display device. If an encrypted signal is
switched to a non-compliant output, a red screen alert or muted screen will be shown.
4.2.1. Protected and Unprotected Content
Many video sources send HDCP protected signal if they detect that the sink is HDCP
capable – even if the content is not copyrighted. This can cause trouble if an HDCP
capable device is connected between the source and the display. In this case, the content
cannot be viewed on non-HDCP capable displays and interfaces like event controllers.
Rental and staging technicians often complain about certain laptops, which always send
HDCP encrypted signals if the receiver device (display, matrix router, etc.) reports HDCP
compliancy. However, HDCP encryption is not required all the time e.g. computer desktop
image, certain laptops still do that.
To avoid unnecessary HDCP encryption, Lightware introduced the HDCP enabling/disabling
function: the HDCP capability can be disabled in the matrix. If HDCP is disabled, the
connected source will detect that the sink is not HDCP capable, and turn off authentication.

4.2.2. Disable Unnecessary Encryption
HDCP-compliant Sink
All the devices are HDCP-compliant, no manual setting is required, both protected and
unprotected content is transmitted and displayed on the sink.
Not HDCP-compliant Sink 1.
Not-HDCP compliant sink is connected to the matrix. Some sources (e.g. computers)
always send HDCP encrypted signals if the receiver device reports HDCP compliancy,
however, HDCP encryption is not required all the time (e.g. computer desktop image). If
HDCP is enabled in the matrix, the image will not be displayed on the sink.
Setting the HDCP parameter to Auto on the output port and disable HDCP on the input port,
the transmitted signal will not be encrypted if the content is not protected. Thus, non-HDCP
compliant sinks will display non-encrypted signal.
Not HDCP-compliant Sink 2.
The layout is the same as in the previous case: non-HDCP compliant display device is
connected to the matrix but the source would send protected content with encryption. If
HDCP is enabled on the input port of the matrix, the source will send encrypted signal. The
sink is not HDCP compliant, thus, it will not display the video signal (but blank/red/muted/
etc. screen). If HDCP is disabled on the input port of the matrix, the source will not send the
signal. The solution is to replace the display device to an HDCP-capable one.
4.2.3. HDCP v2.2
HDCP v2.2 is the latest evolution of copy protection. It is designed to create a secure
connection between a source and a display. The 2.x version of HDCP is not a continuation of
HDCPv1, and is rather a completely different link protection. One of the main differences is
the number of the allowed devices within a closed A/V system: HDCP v2.2 allows 32 devices
(HDCP v1.4 allows 128 devices). Further limit is that up to four level is allowed which means
the protected signal can be transmitted over at most four repeater/matrix/switcher device.
HDCP content protection is activated only if an active video stream is transmitted from the
source to the display. The encryption is not activated without a video signal.
HDCP v2.2 standard allows to apply a previous version of HDCP (e.g. HDCP v1.4) between
the source and the display if the source content allows it. According to the standard if the
image content is protected with HDCP, the highest supported content protection level has
to be applied. However, if the highest level of protection is not justified by the source content
the level may be decreased to avoid compatibility problems; this case is determined by the
source.

HDCP v2.2 Source and HDCP v1.4 Sink
In this case the signal of an HDCP v2.2 compliant source is switched to an HDCP v1.4
compliant sink device. The signal is encrypted with HDCP v2.2 on the input and encrypted
with HDCP v1.4 on the output of the matrix. A lower level of encryption may be applied only
if the source device/content allows it - according to the HDCP standard. In this case the
HDCP setting on the input port has to be set to "HDCP 1.4" and "Depends on input" on the
output port. See the corresponding section 7.4.1 on page 40.
HDCP v1.4 Source and HDCP v2.2 Sink
The below example is the 'reverse' of the previous case. An HDCP v1.4 compliant source
sends a signal with HDCP v1.4 encryption. The signal is switched to an HDCP v2.2
compliant sink device. In this case the outgoing signal has to be encrypted with the highest
supported encryption level towards the sink, as the matrix and the sink are both HDCP v2.2
compliant. The HDCP v2.2 standard does not allow keeping the original HDCP v1.4
encryption level on the output.
What Kind of Signal will be on the Output of the Matrix?
See the below table that summarizes the possible cases:
Incoming Signal HDCP v1.4 Compatible Sink
on the Output
HDCP v2.2. Compatible Sink
on the Output
HDCP v1.4 HDCP v1.4 HDCP v2.2
HDCP v2.2 (convertable)* HDCP v1.4 HDCP v2.2
HDCP v2.2 (not convertable)* Red screen HDCP v2.2
* The incoming video signal contains an information if the encryption level of the signal can be converted to a
lower level of encryption. That information is encoded in the video stream.
