Beckhoff Industrial PC: CU8810 DVI splitter with four DVI/USB channels

Flexible connection to multiple displays

Large machines and widely branched plants increase the demand for local information access. Accordingly, the Beckhoff CU8810 DVI/USB splitter with its compact design offers diverse options for connecting multiple displays. Up to four displays with identical resolution showing the same image or two separate images can be connected to a PC.

The CU8810 enables users to display the same images or two different images on up to four monitors. The images are transferred via DVI; the integrated USB ports transfer command signals from touch screens, function keys, keyboards and other USB devices. The CU8810 contains a 2:4 DVI splitter with 4-port USB 1.1 hub and USB Extended outputs. With the extended technology, the DVI splitter and each Control Panel can be located up to 50 m apart.

The DVI splitter has two DVI-D inputs and four DVI-D outputs; all inputs and outputs operate over the full DVI data rate range up to 1.65 Gbit/s. The following connection versions are possible:

Version 1
A PC with DVI output transfers an identical display image to up to four Control Panels. Command signals can be transferred to the PC via USB from each Control Panel.

Version 2
If two PCs with one DVI output each are used, two different images can be transferred to the Control Panels. The two images may have different screen resolutions.

Version 3
The two-PC principle also works using a PC with Core™ Duo technology. If two DVI outputs are used, two different images can be transferred to the Control Panels. The two images may have different screen resolutions. The two-channel C9900-A185 ADD2 card offers a simple option for installing an additional DVI output. Via the CU8810, both DVI outputs can be branched further to up to four Control Panels.

Version 4
If a Panel PC with DVI output is used (e.g. “Economy” Panel PC CP62xx), the DVI splitter can be used to transfer an image that differs from the main image on the Panel PC to up to four Control Panels. In this case commands can also be transferred via USB from the individual Control Panels to the Panel PC.
