Dvi Outputs - Lightware MX32x32DVI-Pro User Manual

1.5.2 DVI outputs

MX32x32DVI-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
MX32x32DVI-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 MX32x32DVI-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 MX32x32DVI-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.
