Adder ALIF2002T-US – Dual-Head DVI USB IP KVM Transmitter

Product Overview

The Adder ALIF2002T-US is the transmitter unit of the ADDERLink INFINITY Dual 2002, a dual-head or dual-link DVI, USB 2.0, and audio IP KVM extender that runs over a single CATx cable or fiber on a standard Gigabit IP network. It lets you relocate critical computers to a secure, climate-controlled equipment room while operators keep a pixel-perfect desktop experience at the workstation. For facilities planning a KVM over IP extension or a scalable IP KVM matrix, this dual-head DVI KVM transmitter is the computer-side building block of the ADDERLink INFINITY range.

Product Description

The ALIF2002T connects to the source computer's two DVI-D outputs, USB, analog audio, and RS232 serial, then encodes everything for transport across standard 1GbE IP infrastructure. Its spatially lossless encoding with 1:1 pixel mapping delivers color-accurate video with no artefacts — the video the operator sees is the same digital video leaving the remote computer.

Video can be configured as two single-link DVI-D heads at up to 1920 x 1200 @ 60Hz, or as one dual-link display at up to 2560 x 1600 @ 60Hz — useful for high-resolution monitors in broadcast and control environments. USB 2.0 with class control supports keyboards, mice, graphics tablets, jog shuttles, joysticks, and mass storage, and non-HID device classes can be disabled for secure deployments without physically blocking ports. Bi-directional stereo audio runs over 3.5mm jacks, and RS232 passes between units at up to 115,200 baud.

The unit carries both an RJ45 link port and an SFP cage, so installers can choose copper CATx for runs up to 100 meters or fiber transceivers for much greater distances; adding 1GbE network devices extends copper reach in repeatable 100-meter hops. Network teaming across both ports provides full network redundancy for mission-critical applications. Intelligent EDID management passes the true monitor characteristics back to the computer, the Magic Eye feature handles dithered video from Mac Pro graphics cards without degrading link performance, and the fanless 1U metal chassis ships in a zero-config state — no drivers or software required. Paired with the ADDERLink INFINITY Manager (AIM) server, multiple point-to-point extenders become a scalable digital KVM matrix where any workstation links to any networked computer.

Typical Applications

• Broadcast studio production suites with computers racked away from edit positions
• Government space installations requiring secured, centralized computing
• Training room facilities sharing centralized workstations across multiple desks
• Commercial meeting space deployments where equipment noise must be removed from the room

Technical Specifications

Frequently Asked Questions

Is the ALIF2002T-US a complete extension kit?

No. It is the transmitter (computer-side) unit. A compatible ADDERLink INFINITY receiver is required at the user station to complete the link.

Can it drive a single high-resolution monitor instead of two displays?

Yes. The unit supports either two single-link DVI-D heads at up to 1920 x 1200 @ 60Hz or one dual-link display at up to 2560 x 1600 @ 60Hz.

How far can it extend?

Up to 100 meters over a single CATx cable, with each added 1GbE network device extending another 100 meters. The SFP cage accepts fiber transceivers for much longer distances.

Does it require special network infrastructure?

It runs on standard 1GbE IP networks over structured CATx cabling or fiber. 10/100 networks are not supported.

Can it be part of a KVM matrix?

Yes. With the ADDERLink INFINITY Manager (AIM) server, multiple ALIF extenders become a scalable matrix where any workstation can connect to any computer.

Is it suitable for secure environments?

Yes. USB class control can disable non-HID devices such as mass storage, removing the need to physically block USB ports.
