1.2. Description
Lightware MX6x6DVI and MX8x8DVI are single link, MX6x6DVI-DL and
MX8x8DVI-DL are dual link DVI matrix switchers with 6 or 8 DVI inputs and 6 or 8
DVI outputs respectively, that routes any input(s) to any combination of output(s).
The router conforms to DVI 1.0 specification, and switches signals between 25 -
165 MHz pixel clock frequency: from 640x480@60Hz to 1920x1200@60Hz or
2048x1080@60Hz PC resolutions in single link, and up to 3840x2400@30Hz or
4096x2400@24Hz in dual link mode. See section 2.3.1 for more information about
dual link signals.
The input signal is not equalized, therefore only standard length (max. 5 meter)
DVI cables can be used.
The switcher has an RS-232 (or RS-422 optional) and an RJ45 LAN port for
remote control applications and a control panel for local control operation. Front
panel buttons are illuminated and easily relegendable with text for informative
system integration.
Optional components
The router can be ordered with or without the following component parts:
Front panel control buttons (MX-CP-8x8)
EDID router board
LAN interface
Some functions and chapters are only applicable if the relating optional component
is installed in the matrix router

1.5. Understanding EDID
1.5.1. Basics
EDID stands for Extended Display Identification Data. Simply put, EDID is the
passport of display devices (monitors, TV sets, projectors). It contains information

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 1-2. 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.

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.

1.6. 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
identification of the monitor type and capabilities. Most DVI sources (VGA cards,

output DVI video signal.

Advanced EDID Management function that helps system integration. The built in
EDID Router stores and emulates 100 EDID data plus all monitor's EDID that are
connected to the output connectors. First 50 EDID are factory presets, while
memories 51 to 100 are user programmable. 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

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 source is
connected to the input and powered ON.
Info When EDID has been changed, the router toggles the HOTPUG signal for
200 msec. 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.

2.3.1. About Dual link signals
Single link DVI signals use three TMDS wire pairs to carry the picture, plus one
TMDS wire pair for the clock signal. Dual link signals use three more TMDS wire
pairs due to the higher resolution. The extra wires carry the data for every second
line of the picture. Those Lightware DVI matrix routers whose model name includes
a -DL tag can handle dual link signals.
Figure 2-3. Wire pairs of the single link interface
Figure 2-4. Wire pairs of the dual link interface
Info The colors of the wire pairs in the picture represent the color information they carry
and not the color of the actual wires inside the cable.
Info Although the DVI specification describes DVI connectors with fewer pins for single
link connections, some single link cables might be equipped with connectors that
are fully pinned. This could confuse users if the cable is capable of transmitting
dual link signals. Always check if the DVI cable is fully wired, not only equipped
with the full pin connector.
Info Some single link monitors can display dual link signals by showing every second
row of the dual link image, however this way the picture will be inaccurate.

2.3.2. DVI inputs
MX8x8DVI / MX8x8DVI-DL, MX6x6DVI / MX6x6DVI-DL provides 29 pole DVI-I
connectors, however only digital pins are internally connected. This way, users can
plug in any DVI connector, but keep in mind that no analog signals are processed.
Always use high quality DVI cable for connecting sources and displays.
No input equalization is provided.

2.3.3. DVI outputs
MX8x8DVI / MX8x8DVI-DL, MX6x6DVI / MX6x6DVI-DL provides 29 pole DVI-I
connectors for outputs. As standard DVI outputs there can be used limited length
cables, since there is no output amplification applied. For using longer cable runs
on output ports, drive currents can be set higher (see section 4.3.6 on page 32 for
more information about this). To achieve connections between faraway devices,
use fiber optical DVI cables or active DVI repeaters/extenders.
No output reclocking is provided.
Fiber Cable powering
As special feature MX8x8DVI / MX8x8DVI-DL, MX6x6DVI / MX6x6DVI-DL is able
to supply 500 mA current on DDC +5V output (pin 14 on output connectors) to
power fiber optical DVI cables. Standard DVI outputs or VGA cards supply only 55
mA current on +5V output, thus unable to power directly 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.

unit is immediately powered ON when the power cord is connected to the AC
source. The router does not have a power switch, it remains powered on, until AC
line voltage is present.
After powered on, the unit performs a self test, then all front panel buttons light up
for one second. After the self test the router reloads its last configuration and it is
ready to use.
Info At switching ON, the router reloads the latest settings which were used before it
was turning off. The unit has an internal emergency memory which stores all
current settings, and ties configurations. 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 accidentally powering down.
3.2. Front panel operations
3.2.1. CONTROL LOCK
Front panel button operations can be enabled or disabled using CONTROL LOCK
button, while RS-232 / RS-422 and Ethernet control is still enabled. If the button is
not illuminated, front panel button operations are enabled. If it illuminates red
continuously, front panel operations are inhibited.
Press and hold the CONTROL LOCK button for 3 seconds to toggle the control
lock state.
3.2.2. TAKE / AUTOTAKE modes
The router has two different switching modes: TAKE and AUTOTAKE. If the
TAKE / AUTO button is unlit, TAKE mode is active. When the TAKE / AUTO button
continuously lights green, AUTOTAKE mode is selected.
Press and hold the TAKE button for two seconds to toggle between TAKE and
AUTOTAKE modes.
TAKE mode allows the user to make multiple connections and disconnections at
once. This mode is useful when time delay is not allowed between multiple
switching. The commands are only realized when the TAKE button is pressed. If no
button is pressed for two seconds, all preselected actions (which were not realized
with the pressing TAKE) will be ignored, and the router returns to its idle state.
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.

3.2.3. Viewing crosspoint state
User can check the current switching status on the front panel using front panel
buttons. This status view feature is slightly different in TAKE or AUTOTAKE modes
because of different switching philosophy of the two modes.
Info Status view occurs whenever the router has to be switched. After entering the view
state, the user can change the routing configuration. Viewing and switching can be
done after each other, or if nothing is pressed for three seconds, the router returns
to idle state.
View current state in TAKE mode
If all source and destination buttons and TAKE button are unlit (the unit is in TAKE
mode, and no input was selected in last 3 seconds), user can verify both input and
output connections. This informative display will remain for 3 seconds, and then all
button lamps go out. In TAKE mode no accidental change can be done unless
TAKE button is pressed.
For viewing input connections, press and release a source button. Now the
selected source button and all destination buttons will light up which are currently
connected to the selected source.
For viewing output connections, press and release a destination button. Now the
source button which is connected to the selected destination will light up. If no
source button is lighting, the selected destination is in muted state.
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 lighting,
the selected destination is in muted state. By pressing another destination button,
the state of that destination can be seen.
Info Be careful, as in AUTOTAKE mode if a source button is pressed, it is immediately
connected to the last selected destination.

3.2.4. Switching
Creating a connection or multiple connections in TAKE mode
1. First press and release the selected source button. The pressed source
button and all destination buttons which are currently connected to this
source will light up. The dark remaining destination buttons are not
connected to this source. This is an informative display about current status
of the selected input. (view only)
2. Press and release the selected destination button or buttons which has to be
connected to the selected source. The preselected destination button(s)
start(s) blinking.
3. Press and release TAKE button to execute the tie or ties. Now the selected
input is switched to the selected output or to the multiple outputs.
Deselecting or muting in TAKE mode
1. First press and release the selected source button. The pressed source
button and all destination buttons which are currently connected to this
source will light up. The dark remaining destination buttons are not
connected to this source. This is an informative display about current status
of the selected input. (view only)
2. Press and release the selected, green lighting destination button which has
to be disconnected from the selected source. The pressed destination or
multiple destinations will turn dark.
3. Press and release TAKE button to execute disconnection.
Info Deselected destinations are disconnected from any source, thus output devices will
display black image or "no signal" message, or automatically will turn off.
Info Multiple switching and deselecting actions can be done simultaneously, during only
one TAKE action.
Creating a connection in AUTOTAKE mode
