DVI outputs
MX 8x8 DVI Pro provides 24 pole "digital only” DVI-D connectors for output
connections. As standard DVI outputs, there can be used limited length cables,
since there is no output amplification applied. For using longer cable runs at
outputs, use fiber optical DVI cables or active DVI repeaters/extenders.
Output reclocking
MX 8x8 DVI Pro reclocks the signal on all outputs. 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 there can be
seen sparkles, noise and jaggies on the image.
Fiber Cable powering
As special feature MX 8x8 DVI Pro on DDC +5V output (pin 14 on output
connectors) is able to supply 500 mA current 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 MX 8x8 DVI Pro 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.

EDID Management
MX 8x8 DVI Pro provides an EDID Management feature with advanced functions
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 50 to 99 are user
programmable.
On all inputs there can be emulated different or same EDID, that are copied from
EDID router's memory, or the attached monitor. For example, the router can be set
up to emulate any device, that is connected to one of the inputs, and the EDID is
automatically changed, if the monitor is replaced with an other.
EDID is independently programmable for all inputs without affecting each other. All
input has it’s own EDID circuit.
User must not disconnect DVI cables during change an EDID opposite to other
manufacturer’s products.
EDID Router can be controlled with included Matrix Control Software via RS232
port or Ethernet .

2. Operation
POWER
Connect the power cord to the router’s IEC standard power input connector. MX
8x8 DVI RPO 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, all front panel buttons light up for
one second. After the self test the router reloads its last configuration and it is
ready for use.
Info At switching on, the router reloads the latest settings which were used before was
turning off. MX 8x8 DV Pro 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 accindentally powering down.
FRONT PANEL OPERATIONS
TAKE / AUTOTAKE modes

button is unlit, TAKE mode is active. When the TAKE button is continuously lighting
green, AUTOTAKE mode is selected.
Press and hold the TAKE button for two seconds to change between TAKE and
AUTOTAKE modes.
TAKE mode allows the user to make multiple connections and deselections at
once. This mode is useful when time delay is not allowed between multiple
switchings.
AUTOTAKE mode is useful when immediate actions must be done or fast
switching is needed between sources on a destination.
CONTROL LOCK
Front panel button operations can be enabled or disabled using CONTROL LOCK
button, while RS232/422 control is still enabled. If it unlits, front panel button
operations are enabled. If there is a coninuous red lighting, front panel operations
are inhibited.
