Dual head digital video, audio, and USB2.0 over 1GbE IP network. 

Part of the ADDERLink INFINITY 2000 Series



The ADDERLink INFINITY 2124 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.

Product Features

  • Perfect Digital Video, Real Time Control
    Using a spatially-lossless encoding system, with 1:1 pixel mapping, the ADDERLink INFINITY 2124T (ALIF2124) 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.
  • Standard IP Technology
    Using standard IP technology allows a choice of single or dual structured cable (CATx) or fiber connections achieving reliable links without interference combined with the resilience of two network port which provide teaming facility for load balanced systems.
  • 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, which can be repeated many times. Also fitted with SFP cages to accept fiber optic transceivers for much greater distances.
  • USB 2.0 with Class Control
    Supports USB devices including graphics tablets, jog shuttles, joysticks and 3D explorers, alongside mass storage devices. For secure applications, the system can 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.
  • Flexible and Scalable Extender or Switch
    Each ALIF21XX series unit can be configured as a simple extender or self managed distributed KVM switch. Each receiver can see up to 16 sources and rapidly switch between them.
  • ADDERLink® INFINITY Matrix
    With the addition of ADDERLink® INFINITY Management system (AIM) 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.
  • 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 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.
  • Digital Audio
    The ALIF21XX series supports digital audio input via USB and the digital video connector.
