2.5.1. HDMI connector
MX8x8HDMI-PRO matrix provides 8x input and 8x output standard 19
pole HDMI connectors. Always use high quality HDMI cable for connecting
sources and displays.
2.5.2. DVI-I connector
MX8x8DVI-HDCP-PRO contains 8x input and 8x output 29
pole DVI-I connectors. Users can plug in any DVI connector,
but keep in mind that analog signals (such as VGAor RGBHV)
are processed only on certain sinks. Always use high quality DVI cable for connecting

Fiber Cable powering
As a special feature, Pro series matrix switchers provide 500 mA current on +5V output (pin
14 on DVI output connectors and pin 18 on HDMI output connectors) which is sufcient to
supply power to ber optical DVI cables. Standard DVI outputs or VGA cards only supply
55 mA current on +5V output, thus they are unable to directly power a ber optical cable.

EDID stands for Extended Display Identication 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 (Extended
EDID) and dened 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.
3.2. Common problems related to EDID
Problem: „I have changed to a different EDID on MX8x8HDMI-PRO 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 MX8x8DVI-HDCP-PRO 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 Lightware factory preset EDIDs allow only one resolution, forcing
the sources to output only that particular signal. You need to select
the Universal EDID that supports all common VESA resolutions, see
the factory EDID list.
3.3. 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.
DVI standard makes use of EDID data structure for the identication 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.

The transmitters provide Lightware’s Advanced EDID Management function that helps
system integration. The transmitter’s built-in memory stores and emulates pre-programmed
factory EDIDs, user’s EDID and the monitor's EDID that is connected to the receiver. The
transmitter stores the EDID of the attached monitor or projector in a non-volatile memory.
This way the EDID from a monitor is available when the monitor is unplugged or switched
off.
The EDID emulated on the HDMI / DVI / DP input can be copied from the transmitter's
memory (static EDID emulation), or from the last attached monitor’s memory (dynamic
EDID emulation). For example, the transmitter can be set up to emulate a device, which is
connected to the receiver’s DVI output. In this case, the EDID is automatically changed, if
the monitor is replaced with another display device (as long as it has a valid EDID).
Advanced EDID management can be controlled via Lightware Device Controller.
INFO
EDID settings are available in the transmitter only, the receiver is transparent in the video
signal point of view.
INFO
The user is not required to disconnect the HDMI / DVI / DP cable to change an EDID as
opposed to other manufacturer’s products. EDID can be changed even if the source is
connected to the input and powered ON.
INFO
When EDID has been changed, the transmitter 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.
3.4. 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 extenders allow 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.
3.4.1. 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 (e.g. an extender-pair) 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 on the extenders. If HDCP is disabled, the
connected source will detect that the sink is not HDCP capable, and turn off authentication.

3.4.2. Real life examples
HDCP-compliant sink
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.
Non-HDCP compliant sink 1.
Non-HDCP compliant sink displaying unprotected content
Non-HDCP compliant sink is connected to the receiver. 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 receiver, 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.
Non-HDCP compliant sink 2.
Non-HDCP compliant sink and protected content
The layout is the same as in the previous case: non-HDCP compliant display device is
connected to the receiver but the source would send protected content with encryption. If
HDCP is enabled on the output port of the receiver, 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 output port of the receiver, the source will
not send the signal. The solution is to replace the display device to an HDCP-capable one.

3.5. Pixel Accurate Reclocking
Signal reclocking is an essential important procedure in digital signal transmission. After
passing the reclocking circuit, the signal becomes stable and jitter-free, and can be
transmitted over more equipment like processors, or event controllers. Without reclocking,
sparkles, noise and jaggies can be seen on the image.
Lightware’s sophisticated Pixel Accurate Reclocking technology xes more problems than
general TMDS reclocking. It removes not only intra-pair skew but inter-pair skew as well.
The Pixel Accurate Reclocking circuit eliminates the following errors:
Intra-pair skew: skew between the + and - wires within a differential wire pair (e.g. Data2- and
Data2+). It’s caused by different wire lengths or slightly different wire construction
(impedance mismatch) in DVI cable. It results in jitter.
Inter-pair skew: skew between two differential wire pairs in a cable. It’s caused by different
wire pair lengths or different number of twists in the DVI cable. Too much inter-pair skew
results in color shift in the picture or sync loss.
Jitter: signal instability in the time domain. The time difference between two signal transitions
should be a x value, but noise and other effects cause variations.
Noise: electromagnetic interference between other electronic devices such as mobile
phones, motors, etc. and the DVI cable are coupled onto the signal. Too much noise results
in increased jitter.

4. Operation
4.1. Powering on
Connect the power cord to the device’s IEC C14 standard power input connector. The
router is immediately powered ON when the power cord is connected to the AC source (on
Slim-matrices the power switch has to be in position ‘ON’). If the self-test is nished the last
conguration is reloaded and the appliance is ready to use.
INFO
After switching ON, the router reloads the latest settings that were used before it was
turned off. The router has an internal emergency memory that stores all current settings
and tie congurations. This memory is independent from presets and invisible for the user.
This built-in feature helps the system to be ready immediately in case of power failure or
accidental power down.
4.2. Front panel operation
4.2.1. Take / Autotake mode
The router has two different switching modes: TAKE and AUTOTAKE. If the TAKE button
is unlit, TAKE mode is active. When the TAKE button continuously illuminates green,
AUTOTAKE mode is selected. Press and hold the TAKE button for two seconds to change
between TAKE and AUTOTAKE modes.
4.2.1.1. Front panel controls in TAKE mode
Take mode allows the user to connect or disconnect multiple outputs to an input
at once. This mode is useful when the time delay is not allowed between multiple
switching. The commands are only realized when the Take button is pressed.
Switching operation
Step 1. First, press and release the desired source
button. The pressed source button and all
destination buttons which are currently
connected to the source lights up.
Step 2. Press and release the desired destination
buttons which have to be (dis)connected to/
from the selected source. The preselected
destination buttons will blink.
Step 3. Press and release Take button; the selected
input is switched to the selected output(s).
4.2.1.2. Front panel controls in AUTOTAKE mode
Autotake mode is useful when immediate actions must be done or fast switching
is needed between sources on a particular destination. In this mode switching
occurs immediately upon pressing one of the input selector buttons.
Switching operation
Step 1. Press and release the desired destination
button. The pressed destination button and
the actually connected source button light up
green. If no source is connected (the output is
muted) no source button will light up.
Step 2. Press and release the desired source
button. The switch action will be executed
immediately. Switching between sources to
the selected destination can be done directly.

4.2.2. View crosspoint state
User can check the current switching status on the front panel using front panel buttons.
View mode is slightly different in TAKE or AUTOTAKE modes because of different switching
philosophy of the two modes.
INFO
View mode does not mean, that the router has to be switched in different modes, viewing
and switching can be done after each other, without pressing any special buttons.
View current state in TAKE mode
If the router is in TAKE mode, user can verify both input and output connections. In TAKE
mode no accidental change can be done unless TAKE button is pressed.
Press and release a source button. Now the selected
source button and all destination buttons that are
currently connected to the selected source will light
up. This informative display will remain active for 5
seconds, then all buttons turn unlit.
Sample drawing shows that Input 1 is currently connected to the Output 2, 3, and 5 ports.
If every source, destination and TAKE button is unlit
(the unit is in TAKE mode, and no input was selected
in the last 5 seconds), press and release a destination
button to see its current state. Now the source button,
which is connected to the selected destination, will
light up. If no source button is illuminated, the selected destination is in muted state. Upon
pressing another destination button, the last state of the destination can be seen.
Sample drawing shows that Output 3 is connected to the Input 1 port.
View current state in AUTOTAKE mode
In AUTOTAKE mode only states of destinations can be viewed.
Press and release the required destination button.
Now the source button, which is connected to the
selected destination, will light up. If no source button
is illuminated, the selected destination is in muted
state. Upon pressing another destination button, the
last state of the destination can be seen.
4.2.3. View live inputs and attached sinks
Step 1. Press and release Signal Present button.
Step 2. Input buttons will light
up indicating that active
TMDS clock signal is
present on respective input
connectors. Output buttons will also light up indicating that a powered monitor is
attached to the output. The output circuit senses TMDS pull-up resistors on monitor
side.
Step 3. Press and release Signal Present button to quit this mode.
Sample drawing shows that the current live inputs are 1 and 3, the current live output is
the 8.
4.2.4. Save or load presets
The unit has 32 user programmable presets. Each preset stores a
conguration regarding all input connections for all outputs. All presets
are stored in a non-volatile memory. The router keeps presets even in
case of power down. Memory numbers are assigned to source buttons.
