Adder ALIF2020P is a high performance Dual-monitor single-link DVI, USB and Audio KVM Extender / Matrix Switch solution including a Adder ALIF2020T Transmitter and a ALIF2020R Receiver.
Part of the ADDERLink INFINITY series, the ADDERLink Infinity Dual 2020 is a high performance KVM solution that enables you to locate your critical computing hardware in a secure and temperature controlled environment, isolated from the user work station. Configurable as a single link or dual head at a maximum of 1920 x 1200 at 60Hz, this extender provides an 'at-the-PC' experience up to 6.21mi (10km) via interchangeable CatX and Fiber SFP modules. This KVM extender can be used as a point-to-point extender, or integrated into a wider matrix system when combined with the ADDERLink INFINITY Manager (A.I.M.).
Adder ALIF2020P Features
Infinite Flexibility
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.
- Point-to-point extension (local / over-IP)
- AV / KVM Switch multi-point matrix (over-IP)
- Sharing a single target (over-IP)
- Multicasting to many receivers (over-IP)
Perfect digital video, real time control
Uncompressed video extension and pixel perfect digital video up to 24 bits per color at a maximum of 1920x1200 over 60hz with 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 or Fiber cable with immunity from interference
The AdderLink Infinity units were designed from the outset around a highly robust signaling method. This vital core asset is what gives you the freedom to use the full variety of cable links that you typically find within an average structured cabling system. The result is that you can achieve reliable links, regardless of whether the cables are CAT5e, CAT6 or CAT7. The AdderLink Infinity dual 2020 also offers the option of up to 6.21mi (10km) distances with fiber.
Unlimited extension distances
Extension distance is not limited to a single 330 foot (100 meter) cable length - If you need to extend further, simply add a 1GbE network device to achieve an additional 330 feet (100 meters). This can be repeated many times. The units are also fitted with SFP cages to accept fiber optic transceivers which enable much greater extension distances.
USB 2.0 with emulation and 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. True USB Emulation Technology allows for faster keyboard and mouse switching. 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.
Enterprise-grade security
Adder Infinity units have built-in security measures compliant with universal enterprise grade security standards inlcuding AES 256 bit encryption and RSA 2048 bit public key authentication.
Intelligent 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 the additional configuration.
Redundant network operation
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
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. ALIF2020T has a feature called Magic Eye which supports dithering without allowing it to degrade overall link performance.
Plug and Play
AdderLink Infinity extender devices are delivered in a zero configuration 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.
