CX1000-N001 connections
In addition to the Ethernet and RS232 interface, 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 7 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.
