Adder ALIF2020R – INFINITY Dual-Head DVI IP KVM Receiver

Product Overview

The Adder ALIF2020R is the receiver unit of the ADDERLink INFINITY Dual 2020 system, delivering dual-head single-link DVI-D video, USB 2.0, and bi-directional analog audio to a user console over a standard 1GbE IP network. It sits at the operator's desk, decoding pixel-perfect video from a remote ALIF2020 transmitter so computers can live in a secure, temperature-controlled room — across the building or up to 20km away over fiber. As a dual-head DVI IP KVM receiver for point-to-point extension or AIM-managed matrix deployments, the ALIF2020R supports two displays at 1920x1200 @ 60Hz with real-time control.

Product Description

The ALIF2020R uses Adder's spatially-lossless encoding with 1:1 pixel mapping, so the video presented on the console displays is identical to the digital output of the remote computer — no artifacts, color shifts, or perceptible latency. Two single-link DVI-D outputs drive a dual-monitor desk at up to 1920x1200 @ 60Hz each, and a Magic Eye feature handles the dithered video produced by Mac Pro graphics hardware without degrading link performance.

Connectivity is standard IP: an RJ45 port handles copper runs to 100m per segment (extendable indefinitely through 1GbE network devices), while an SFP cage accepts fiber transceivers for distances up to 20km. Both links can be teamed for redundant network operation, an important resilience measure in mission-critical control positions. Four True Emulation USB 2.0 ports support keyboards, mice, graphics tablets, jog shuttles, joysticks, and mass storage, with class control available to disable non-HID devices in security-conscious installations — no physical port blocking required.

Deployed point-to-point with the matching ALIF2020T transmitter, the pair forms a zero-config extender that works on connection — no drivers or software. Added to an ADDERLink INFINITY Manager (AIM), the same receiver becomes a station on a scalable IP KVM matrix with any-station-to-any-computer routing. The fanless 1U metal chassis carries a 500,000-hour MTBF rating, suiting 24/7 operation.

Key Features

• Pixel-Perfect Dual-Head Video — Spatially-lossless encoding with 1:1 pixel mapping delivers two single-link DVI-D streams at up to 1920x1200 @ 60Hz with no artifacts.
• Copper and Fiber Connectivity — RJ45 for CATx plus an SFP cage for fiber transceivers reaching up to 20km; extension is repeatable through standard 1GbE network devices.
• Redundant Network Teaming — Dual links can be teamed for full network redundancy in mission-critical installations.
• USB 2.0 with Class Control — Four True Emulation USB ports support tablets, jog shuttles, joysticks, and storage, with the option to disable non-HID devices for security.
• AIM Matrix Ready — Joins an ADDERLink INFINITY Manager deployment to give the station access to any computer on the matrix network.
• Mac Pro Dithered Video Support — The Magic Eye feature accommodates dithered graphics output without degrading link performance.
• Bi-Directional Stereo Audio — 3.5mm input and output jacks carry 16-bit/48kHz analog audio both ways.
• Zero-Config and Fanless — No drivers or software required; silent fanless chassis with 500,000 h MTBF for always-on duty.

Typical Applications

• Broadcast studio operator positions linked to a central machine room
• Government space consoles separated from secured computing hardware
• Training room stations on an AIM-managed KVM matrix
• Commercial meeting space desks accessing racked presentation systems

Frequently Asked Questions

Does the ALIF2020R require a matching transmitter?
Yes. It receives from an ALIF2020T transmitter connected to the source computer, either point-to-point or across an AIM-managed matrix.

How far can it be from the computer?
100m per copper segment, extendable repeatedly through 1GbE network devices, and up to 20km over fiber using SFP transceivers.

Can it join a KVM matrix later?
Yes. Adding an ADDERLink INFINITY Manager (AIM) converts point-to-point ALIF endpoints into a scalable matrix with any-station-to-any-computer routing, co-operative sharing, and video multicasting.

Are USB storage devices supported — and can they be blocked?
Mass storage and specialty HID devices are supported through the four USB 2.0 ports, and class control can disable non-HID devices for secure environments. Isochronous USB devices (e.g., USB audio/video) are not supported.

Is special network hardware required?
No. The system runs over standard 1GbE IP infrastructure with either CATx or fiber links.

What about installation software?
None is needed. Units ship zero-config and operate as soon as they are connected; intelligent EDID management is automatic.
