The ADDERLink INFINITY 2122 is a high performance IP KVM (Keyboard, Video and Mouse) extender that forms part of the ALIF matrix solution. This enables the relocation of critical computing hardware into a secure and temperature controlled environment away from the user work station; whilst maintaining a pixel-perfect desktop experience.


Plug and play

2 x SFP ports for maximum flexibility. Can be used with either CATx or fiber modules, allowing distances of up to 20km

Video resolutions up to 1x 2560x1600 @60Hz or 2x 1920x1200 @60Hz

USB mass storage devices supported plus keyboard, mouse, tablet and touch

Support for Mac Pro®

Redundant network operation

Dual touch screen support including onscreen keyboard and floating launch button

Product Features

Perfect digital video, real time control

Using a spatially-lossless encoding system, with 1:1 pixel mapping, the ADDERLink INFINITY (ALIF) 2122 provides pixel-perfect and color accurate video with no artifacts. The digital video received is the same as the digital video leaving the remote computer.


Single CATx cable or fiber with immunity from interference

Using standard IP technology allows a choice of single structured cable (CATx) or fiber connection achieving reliable links without interference.


Extension distances

Extension distance is not limited to a single 100m/328ft cable length - it can be extended further by adding a 1GbE network device to achieve an additional 100m/328ft. The units are fitted with SFP cages to accept fiber optic transceivers which enable much greater extension distances of up to 20km/12mi.


Support for Mac Pro® (Dithered Video)

Some graphics cards use a technique called dithering to give the appearance of a deeper color depth than is actually the case. Dithering can significantly increase the normal video data rates. The ALIF2122 TX has a feature called Magic Eye which supports dithering without allowing it to degrade overall link performance.


USB2.0 with class control

Enables connection of USB devices such as mouse and keyboard, graphics tablets, jog shuttles, joysticks, and 3D explorers, alongside mass storage devices. For applications where security is of high importance, the system has the ability to disable the use of non-HID devices, meaning there is no need to physically block USB ports to prevent the use of mass storage devices.


EDID management

Intelligent EDID management allows the true characteristics of the monitor to be passed back to the computer. This ensures perfect video display without additional configuration.


Plug and Play

All ALIF extender devices are delivered in a zero config state so you can plug them in and start working on them straight away. There is no need for drivers or software to be installed.


Redundant network operation

The units support network teaming allowing for full network redundancy and increased resilience for mission critical applications.



With the addition of the ADDERLink INFINITY Management System (AIM), multiple point-to-point extenders can be turned into a truly scalable digital KVM matrix system, that allows any workstation to link with any computer connected to the network.
