Welcome  Products  Digital KVM matrix systems  Computer modules

Computer modules for digital matrix systems

Computer modules connect the external computer interfaces keyboard, video, mouse and audio with the central module. The signals are combined, processed and transmitted via CAT x cable or optical fibres.

Any computer module has a unique ID that helps identifying the device within a digital matrix system.

We provide the following computer module variants:

Computer modules for digital matrix systems

Basic computer modules

The basic computer modules make it possible to configure your system to exactly fit your needs. They are divided by the transmitted video signal and are available in additional variants. These expansion stages and additional functions can be found below.

Integrate high resolutions into the system

DP-HR components let you integrate graphics cards and monitors with DisplayPort connectors at high resolutions into Control Center Digital and DVICenter matrix switch systems. A bandwidth up to 300 Mpixels/s allows resolutions up to 2560x1600/60Hz or 4096x2160/30Hz.

The transmission takes place via CAT cables or optical fibers (only for ControlCenter-Digital) thus allowing transmission distances of up to 10,000 m.

The computer modules DP-HR CPU are available in different expansions and differ based on the number of video channels, the transmission medium, the transparent USB transfer and the possibility of controlling redundant matrix switch clusters.

Standard module for DisplayPort sources

DP-CPU is a standard module for the integration of DisplayPort into the matrix.

The DP-CPU combines keyboard, video, mouse, and audio signals, converts DisplayPort into single-link DVI and uses CAT cables to link them to the KVM matrix switch. Integrating the user module DVI-CON the signals are provided at the remote workstation.

Standard module for Single-Link DVI

Standard variant transmitting the following signals:

  • Single-link DVI-D
  • PS/2 + USB keyboard/mouse
  • Audio (Line In / Line Out)

The communication with Wacom Intuos3 or 4® tablets is supported.

Front view VGA-CPU-UC

Standard module for VGA video

Module to connect a VGA computer to the matrix The VGA-CPU combines keyboard, video, mouse, and audio signals and uses CAT cables to link them to the central module.

The module transmits the following signals:

  • VGA
  • Keyboard/Mouse (USB & PS/2)
  • Audio

Resolution: VGA up to 1920 x 1440 @ 75 Hz

Rear view U2-R-CPU
Front view U2-R-CPU

Standard module for transparent USB 2.0

The U2-R-CPU transmits the following signals:

  • USB 2.0 Hi-Speed
  • RS232

The transmission of the signals occurs transparently. The distance lenght between the U2-R CPU module and the KVM matrix switch can be up to 140 meters.

Additional computer module variants

The following additional variants add more signals and functions to the basic computer modules.

Transmit two video signals via one cable

The new DH (DualHead) variants allow transmitting two video signals via one transmission cable. Following resolutions are possible:

  • One channel usage:
    • up to 2560 x 1600 @ 60Hz (2K)
    • or 4096 x 2160 @ 30Hz (4K)
  • Two channel usage:
    • up to 2 x 1920 x 1200 @ 60Hz
    • if there is less resolution and transmission on the second video channel, the first channel can transmit a higher resolution (330 MPixel/s total bandwith)

This module makes it possible to establish multi-monitor workstations in combination with the corresponding user modules.

The new cabling comes with significant advantages: transmitting two video signals on one line saves 50% of the ports at the central switch – and therefore does not only result in less complex cabling but also in a significant commercial advantage, which can be in the form of a smaller matrix switch.

Available for:


Connect computers to two different matrix systems

With the "UC" module you can connect one computer to two different matrix switches (clusters).

The module owns two RJ45 sockets. Each is connected to another matrix switch.

You can connect to the computer from each of the connected clusters.

Available for:

  • DP-CPU

Increasing range via fibre optics

We use fibre optics to expand the transmission length to the central module. With this module you can use the benefits of this medium. To use this module you also have to install a corresponding IO card in the central module.

Note: can not be used with ControlCenter-Compact and DVICenter central modules

The transmission length to the central module depends on the used module and is up to 10,000 m.

  • Fiber(M) bridges up to 400 m
  • Fiber(S) bridges up to 5,000m
  • Fiber(S+) bridges up to 10,000m
Rear view DVI-CPU-Fiber-UC

Available for:


Integrated USB transmission without extra wiring

With the "U" variant it is possible to transmit transparent USB without any additional devices. There is no need for additional cables or devices.

This solution achieves a transmission rate up to 16 Mbit/s. For higher rates you need the U2-R-CPU.

Available for:

  • DP-CPU

Connect computers with more video channels to the system

Computer module to establish multi-monitor workstations in combination with the corresponding user modules DVI-CON-MC2 or -MC4.

Front view DVI-CPU-MC2

Available for:


Optimized rack mounting

The FSC variant offers all the connectors of the device on the front. This solution was especially designed for rackmount usage.

This solution was designed for using it with our mounting solutions.

Terminal side DVI-CPU-FSC

Available for:


Power supply according to your needs

You can order the computer modules without the included power supply.

Order the MultiPower if the computer modules have to be supplied with power from a central source.

Available for:

  • DP-CPU

Mix & Match with extenders

Mix & Match

All products signed with this icon can be used together. Computer or user modules for matrix systems can be mixed with extender systems. Extender systems can also be used in the matrix . For example: a DP-CPU computer module can be directly connected to a DVI-Vision-CAT-CON to establish an extender system.

This provides full flexibility and hepls at future-oriented planning of growing systems.

G&D Optimized mounting solutions for rack installation

Optimized mounting solutions for rack installation

Our computer modules can be perfectly assembled with our optimized rackmount solutions. You can find them under the point mounting solutions.

A central power supply can be realised with our MultiPower devices.
