BECKHOFF CX9020 - Manual (Page 23)

Mounting and wiring
3.6 DVI­D port
DVI­D port (X200)
The DVI­D interface transfers digital data and is suitable for connecting a digital display. 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 metres possible.
Note
DVI­DInterface
The DVI interface does not use VGA signals, so that the connection of CRT VGA monitors
to the CX9020 system using a DVI to VGA adapter is not possible.
