5.3 DVI-I (X200)
The DVI-I interface (X200) transfers digital data and is suitable for connection to digital or analog monitors.
The resolution at the display or the Beckhoff Control Panel depends on the distance from the display device.
The maximum distance is 5 m. Beckhoff offers various Panels with an integrated “DVI extension”. These
make a cable length of up to 50 meters possible.
