3.4.1. DVI inputs and outputs

DVI Inputs
UMX4x4-Pro2 matrix switchers provide standard 29 pole DVI-I connectors for inputs. This
way, users can plug in any DVI connector, but keep in mind that analog signals (such as
VGA or RGBHV) are processed only on the DVI inputs.
Always use high quality DVI cable for connecting sources and displays.

- These pins are connected only on the DVI inputs.
DVI outputs
29 pole DVI-I connectors for outputs have only digital pins internally connected. This way,
users can plug in any DVI connector, but keep in mind that analog signals (such as VGA
or RGBHV) are NOT available on the outputs.
Fiber Cable powering
DVI outputs are able to supply 500 mA current on DDC +5V output (pin 14 on output
connectors) which is sufficient to supply power to fiber optical DVI cables. Standard DVI
outputs usually supply only 55 mA current on +5V output, thus unable to directly power 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.
