Jamie Adkin From ADDER Technology explains how the AIM Management appliance controls the ADDERLink Infinity / Infinity Dual.


End Design sold its first KVM extender from Cambridge based Adder Technology for over 12 years ago. Since then Adder has become a by-word for quality and reliability. The ADDERLink INFINITY takes the fluid interaction with computers to another level by delivering USB and spacially lossless digital Video as far away as your network can extend.

ADDERLink INFINITY allows you to build a flexible infrastructure that was simply not possible before. Locate computers anywhere, share connections to computers, watch the interactions others have with computers, share control, collaborate, switch computers and so on.

The ADDERLink INFINITY is also the first device of its kind to allow multicasting across your network. Adder's expertise in IP based KVM solutions also means that you get the very best video quality and fluid USB based interactions with your computer. USB True Emulation technology has also been built into the ADDERLink INFINITY, allowing you to connect all Human Interface and storage devices as well as many other USB device types too.

Flexible Usage Architecture

The ADDERLink INFINITY can be configured to deliver the ultimate in system flexibility.

Infinity application diagram

In the diagram above, we can see the use of two remote computers resulting in several very distinct usage scenarios:

Multicasting: The video output from any transmitter can be multicast to many receivers. The video data only exists once on the network, and each connected user (receiver) can view the output simultaneously.

Full Control: This user has full control of computer 1. They are viewing the video output, listening to the audio, using a local USB peripheral and they have full keyboard and mouse control.

Mixed Receiver: Here a user is viewing the output video from computer 2 with full keyboard, mouse and local USB device control at the user's desk. At the same time, this user is listening to audio from Computer 1.

A/V Only: This user position is configured to display video and play audio only. A/V selection may be from different sources.

Share Mode: In share mode, two or more users have simultaneous access to a shared computer enabling collaboration or advanced control applications.

Any to Any: In Any to Any mode, connections are fully independent enabling one user to access the first computer whilst another user accesses another computer etc. This mode supports large scalable matrix switching scenarios.

Key Features

Perfect Digital Video The ADDERLink INFINITY is spatially-lossless with 1:1 pixel mapping, so the digital video you receive is the same as the digital video leaving the remote computer.

Intelligent Video Encoding The ADDERLink INFINITY uses optimal spatially-lossless compression techniques to minimize network bandwidth usage. With typical computer desktop applications, the ADDERLink INFINITY uses remarkably little bandwidth. When it needs to deliver full screen motion video, it has the capability to process full screen moving video in real time.

Video Colour Accuracy The received video colour is the same as the sent colour every time. There is never a loss of clarity with the ADDERLink INFINITY. Because of this, colour controlled environments such as visual media or scientific imaging can collaborate in real time on projects, handing control across seamlessly to other group members.


USB True Emulation The ADDERLink INFINITY enables you to connect any USB human interface device from mice and keyboards through to graphics tablets, jog shuttles, joysticks and 3D explorers. furthermore, most other USB devices can also be attached, such as Mass Storage devices.

Network Topology You can configure your network topology to best suit your needs. If you simply want to extend one computer Tx to one user Rx, you can do so by connecting both Tx and Rx units via a low cost CATx cable. Distance is not limited - a standard network cable will deliver IP traffic up to 100 metres away. If you want to go further, simply add a network switch to achieve an additional 100 metres. This can be done many times if you wish. The ADDERLink INFINITY network is assumed to be a private network which you manage.  As such, you can control maximum data rates generated by each Tx unit to ensure absolute stability.

Wireless Connectivity Because of the efficient manner in which ADDERLink INFINITY constructs data for IP transmission, it is perfectly reasonable to make use of standard off-the-shelf wireless routing to connect either Rx or Tx units to your network. Typical desktop applications (word processing, spreadsheets etc.) will use very little bandwidth.

DVI - Digital Visual Interface The ADDERLink INFINITY features full DVI connectivity. DVI delivers native digital video signals from your computer to your digital panel (LCD for example) without the need to convert signal types from the digital domain. By delivering native digital video throughout the ADDERLink INFINITY network, you can be assured of accuracy on each and every pixel.

USB 2.0 The ADDERLink INFINITY uses USB 2.0 connectivity to interface with your keyboard and mouse, and any other peripheral you wish to use. USB is the most broadly used computer peripheral interface standard available.

Digital Stereo Audio ADDERLink INFINITY delivers crystal clear stereo audio digitally across the network. This ensures continuous fidelity and channel separation between the Tx and Rx units, or even in Multicast environments.

ADDERLink INFINITY Management System (A.I.M.)

AIM Management interface

By making use of the ADDERLink INFINITY Management System, you can administrate the entire network and apply a flexible selection of connectivity rules. For example, you may wish to allow only certain users to access video from a remote computer, apply sharing hierarchy to users, or make all users view a predefined channel mixture.

The ADDERLink INFINITY Management system allows you to combine elements from remote computers and save those combinations as 'channels'. Your users can then pull up the advanced EPG (Electronic Program Guide) on their receiver and change channel, in much the same way as you would a digital TV. If two receivers wish to collaborate on a machine, or get technical support, they can both share keyboard and mouse control at the same time.

Screen grouping allows you to switch multiple video feeds together whilst using a single keyboard and mouse, ideal for use on multi- head computers.

The ADDERLink INFINITY Management System is simplicity itself to use, and because it sits on your network, you can access it from anywhere you like, day or night. You can even access usage logs which tell you which receivers have been connected to which transmitters over time, what collaboration has occurred and who is connected at any point in time.
