Move the user interface away from the rack without sacrificing control. Black Box ACU2500A-R3 extends HDMI and USB 2.0 signals over CAT5e up to 100 meters, giving IT teams the distance they need for secure, practical workstation placement in server rooms, control areas, and equipment closets. This extender is built for environments where direct access to the host system is inconvenient or disruptive. By carrying video and USB over standard CAT5e cabling, it reduces the need for long peripheral runs and helps keep equipment concentrated in a protected location. That matters when uptime, cable management, and operator access all need to align. For infrastructure teams, the value is in the separation: users get a responsive local experience while the hardware stays where it belongs. The result is a cleaner deployment model for remote consoles, industrial stations, and AV-adjacent IT spaces that need dependable extension without moving the source equipment. When compared with short-range or consumer-grade alternatives, this model is aimed at professional installations that need predictable reach and a purpose-built KVM extension path.
