Embedded PC  31 
CX1020-N001 connections 
 
 
 
In addition to the two Ethernet interfaces, this module features a DVI-I and two USB interfaces. 
DVI-I interface 
The DVI-I interface transfers analog and digital data and is suitable for connection to analog graphics cards with 15 
pin D-Sub connector and digital graphics cards with DVI-D output. The resolution at the screen or the Beckhoff 
Control Panel depends on the distance (maximum 5 m). 
The DVI interface uses VGA signals, so that the connection of CRT VGA monitors to the CX1000 system using a DVI 
to VGA adapter is also possible. 
This adapter is available as an accessory.
