DVI outputs
MX 4x4 DVI and MX 4x4 DVI DL 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.
Fiber Cable powering
As special feature MX4x4DVI and MX4x4DVI-DL 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 graphics cards supply only 55 mA current on +5V
output, thus unable to power directly a fiber optical cable.
Info MX4x4DVI and MX4x4DVI-DL 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.
