ADDERLink INFINITY dual 2020


Dual head, single link digital video and USB2.0 over a single cableADDERLink INFINITY dual 2020 Tx Unit

AdderLink Infinity (ALIF) dual 2020 is an IP-based high performance KVM (Keyboard, Video and Mouse) extender that forms part of the ALIF matrix solution. This enables you to locate your critical computing hardware in a secure and temperature controlled environment away from the user work station, whilst maintaining a pixel perfect desktop experience.

Fully compatible with the ADDERLink INFINITY Matrix range.

Perfect digital video, real time control

Using a spatially-lossless encoding system, with 1:1 pixel mapping, AdderLink Infinity provides pixel perfect and color accurate video with no artefacts. The digital video you receive is the same as the digital video leaving the remote computer.

Single CATx cable or fiber with immunity from interferenceADDERLink INFINITY dual 2020 Rx Unit

Using standard IP technology means you have the choice of a single structured cable (CATx) or fiber connection. The result is that you achieve reliable links without interferance. The AdderLink Infinity dual 2020 also offers the option of up to 10km distances with fiber.

Unlimited extension distances

Extension distance is not limited to a single 100 meter cable length – If you need to extend further, simply add a 1GbE network device to achieve an additional 100 meters. The units are also fitted with SFP cages to accept fiber optic transceivers which enable much greater extension distances.

Support for MacPro (Dithered Video)

Some graphics cards use a technique called dithering to give the appearance of a deeper color depth than is actually the case. As a result, dithering can significantly increase the normal video data rates. ALIF2002T has a feature called Magic Eye which supports dithering without allowing it to degrade overall link performance.

USB 2.0 with class control

Enables connection of USB devices from mice and keyboards through to 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

AdderLink Infinity 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 operationADDERLink INFINITY dual 2020 Rx Unit

The units are able to detect whether the network is in operation and can automatically change to its second network port if it detects a failure.

AdderLink Infinity Matrix

With the addition of AdderLink Infinity Management system (A.I.M.) you can turn multiple point-to-point extenders into a truly scalable digital KVM matrix system that allows any workstation to link with any computer connected to the network. See the Adderlink Infinity Matrix data sheet for details.

Hardware compatibility

All computers with DVI-D, USB, audio, RS232 – requirement dependent.

DVI-D – Digital Visual Interface (digital only)

The system supports two Single Link DVI-D resolutions to a maximum of 1920 x 1200 @ 60Hz.

USB 2.0 with class control

Supports USB2.0 devices (low, full and high speed). Security feature allows the blocking of non HID devices. Isochronous devices are not supported (e.g. USB audio or video devices).

Digital stereo audio

The system transfers analog stereo audio (Line In/Line Out) via digital signaling between any transmitter/receiver pair. Additionally, the audio output of any transmitter can be multicast to many receivers.


RS232 can be passed between the units to a maximum baud rate of 115,200. RS232 is a point to point connection technology and cannot be multicast.

Software compatibility
