AV extender Adder ALIF2020R-IEC HD video audio transmission

The AdderLink Infinity (ALIF) dual 2020 is an IP-based high-performance KVM extender that separates critical computing hardware from the user workstation while preserving a pixel-perfect desktop experience. It transmits digital video and USB signals over a single CATx cable or fibre, supports extended distances with SFP fibre transceivers, and integrates with the AdderLink Infinity matrix solution for scalable multi-user switching.

Advantages

ALIF dual 2020 uses spatially-lossless encoding with 1:1 pixel mapping to deliver pixel-perfect, colour-accurate video with no artefacts. It supports USB 2.0 class control for a wide range of HID and mass-storage devices and provides EDID management so the display’s true characteristics are passed back to the host. The product offers redundancy with dual network ports, plug-and-play zero-config operation, and Magic Eye support to handle dithered video from graphics cards such as Mac Pro outputs.

Suitable for

• Broadcast and production control rooms where secure, remote hardware placement is required
• Financial trading desks and control centres needing low-latency, pixel-perfect desktop access
• Medical imaging and imaging review stations requiring colour-accurate video
• Industrial and secure facilities where equipment must be located in temperature-controlled environments

Key specifications

• Device type: IP-based KVM/AV extender (AdderLink Infinity ALIF series)
• Video: Spatially-lossless encoding, 1:1 pixel mapping, pixel-perfect digital video
• Connectivity: Single CATx or fibre; SFP cages for fibre transceivers; dual network ports for redundancy
• USB: USB 2.0 with class control, supports HID devices and optional blocking of non-HID mass storage
• Distance: Up to 10 km over fibre; unlimited extension via 1GbE network devices
• EDID: Intelligent EDID management
• Operation: Plug-and-play, zero configuration; compatible with AdderLink Infinity Matrix via A.I.M.

How to use

Connect the ALIF transmitter to the source computer and the receiver to the user workstation using a single CATx cable for local links or install appropriate SFP fibre transceivers for long-distance fibre connections. Power up both units; they operate in a zero-config state so no drivers are required. Configure USB class control or disable non-HID devices if you need to restrict mass-storage access. For matrix deployments, add the AdderLink Infinity Management (A.I.M.) system to allow workstation-to-computer linking and centralized management.

Usage recommendations

Use shielded CATx cabling in electrically noisy environments or choose fibre transceivers for maximum immunity to interference and extended distances. Enable EDID management to ensure correct monitor characteristics are communicated to the host, and consider redundant network wiring to take advantage of the unit’s automatic failover.
