DVI-D connection
DVI-D connection (X200)
The DVI-D interface transfers digital display data and is suitable for connecting a digital display. The maximum length of the DVI cable is determined by screen resolution and quality of the DVI cable. Without the use of special electronics, a DVI cable length of 5m should not be exceeded. Beckhoff offers various displays with integrated DVI extension electronics, enabling DVI cable length up to 50m.
 | DVI-D interface The DVI interface does not use VGA signals, so that the connection of CRT VGA monitors to the CX50x0 system using a DVI to VGA adapter is not possible. |
