Description of the interfaces
CX20x2 22 Version: 1.7
5.4 Optional interfaces
5.4.1 DVI-D (N010)
The DVI-D interface (X300) transfers digital data and is suitable for connection to digital displays. If the
optional N010 interface (DVI-D interface) is used, the first DVI-I interface can be operated either in VGA
mode or in DVI mode. 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.

The Embedded PC also supports higher resolutions, based on the DVI standard. A maximum resolution of
2560 x 1440 pixels can be set on the Embedded PC. Whether this resolution is achieved depends on the
monitor, the cable quality and the cable length.
