Move the console away from the equipment without losing the connections that matter. The Black Box ACU5501A-R4 extends DVI-D video, USB, and audio over CATx cabling up to 50 m, giving infrastructure teams a cleaner way to position workstations, protect sensitive hardware, and improve access in constrained spaces. This is the right tool when a direct cable run is no longer practical. By carrying video, peripheral control, and audio over a single CATx path, it reduces cable sprawl and makes it easier to separate operators from servers, industrial systems, or secure devices. That matters in control rooms, production areas, and technical spaces where distance, noise, or physical access are part of the design. For organizations that value uptime and disciplined workspace layout, the ACU5501A-R4 delivers a more deliberate deployment model than short-range cabling or consumer-grade extenders. It is built for environments where signal reach, console placement, and operational clarity all affect performance.
