Black Box ACU075A-USB Short-Range VGA USB KVM Extender over CATx

Overview

The Black Box ACU075A-USB is a short-range KVM extender designed to push VGA video and USB keyboard/mouse signals up to 75 feet over standard CATx cabling. If you need to relocate a workstation, server console, or control-room terminal away from the host equipment without running bulky VGA or USB cable runs, this unit lets you do it with infrastructure you likely already have on the rack or in the wall.

Key Features

• 75-Foot CATx Extension: Reaches 75 ft over standard Cat5e or Cat6 — meaning you can move a console operator station across a control room or to an adjacent rack bay without pulling new coax or VGA cable. That's a practical distance for most KVM switching deployments in server rooms, broadcast racks, and operations centers.
• VGA Video Signal: Carries analog VGA, which covers the broad installed base of legacy industrial monitors, HMI displays, and operator consoles still in active use. If your target display or source device is already VGA-native, there is no adapter chain to maintain.
• USB Connectivity: The ACU075A-USB (often searched as ACU075A USB) extends USB peripherals — keyboard and mouse — alongside the video signal, keeping the operator's control interface fully functional at the remote end without a separate USB extender or hub.
• CATx Infrastructure Reuse: Using existing structured cabling infrastructure instead of proprietary cable lowers deployment cost and simplifies future moves. A single CATx run handles both video and control data.

Integration and Compatibility

The ACU075A-USB is designed for environments running VGA-output sources — workstations, servers, industrial PCs, or AV equipment with standard VGA ports — paired with USB HID peripherals. It is not intended for DisplayPort or HDMI sources; those require a different extender family. Verify that your source and display both carry native VGA ports before specifying this unit. For deployments requiring longer extension distances or digital video (DVI/HDMI/DisplayPort), consider a higher-specification model within the Black Box extender line.

Frequently Asked Questions

Q: What cable type does the ACU075A-USB require between the local and remote units?

A: The ACU075A-USB transmits over CATx cabling (Cat5e or Cat6 are standard choices). This lets you reuse existing structured cabling runs rather than pulling dedicated proprietary cable.

Q: Does the ACU075A-USB support USB devices other than keyboard and mouse?

A: Based on available product information, the ACU075A-USB is designed for USB HID peripherals — keyboard and mouse. Compatibility with other USB device classes (storage, audio, etc.) is not confirmed in the available evidence; verify with Black Box directly for non-HID USB use cases.

Q: What is the maximum extension distance for the ACU075A-USB?

A: The ACU075A-USB supports a maximum extension distance of 75 feet (approximately 23 meters) over CATx cable.

Q: Can the ACU075A-USB extend HDMI or DisplayPort signals?

A: No. The ACU075A-USB is a VGA extender. HDMI and DisplayPort sources require a different extender model. Confirm your source output type before ordering.

Q: Does the ACU075A-USB require external power?

A: Power requirements for the ACU075A-USB are not confirmed in the available product evidence. Contact Black Box or your reseller for clarification on power sourcing before installation planning.

The ACU075A-USB fills a specific gap: you have a VGA+USB console that needs to sit 75 feet away from the host, you have CATx in the wall, and you don't want to budget for a full digital extender platform. That's the honest use case for this unit — practical, infrastructure-reusing, no-frills console relocation.

Technical Highlights:

• 75-Foot CATx Reach: Covers the typical control-room or server-bay console relocation distance without requiring proprietary cabling — Cat5e or Cat6 that's already in the path handles the job.
• VGA + USB in One Run: Combining video and HID peripheral extension over a single CATx run keeps the cable count down at both the local and remote ends — no separate USB extender needed for keyboard and mouse.
• VGA Signal Type: Analog VGA is the right call for legacy industrial monitors, HMI terminals, and older operator consoles that aren't going to digital outputs anytime soon. No signal conversion overhead, no compatibility surprises on the display side.

Deployment Considerations:

• Confirm both the source device and the target display carry native VGA ports before specifying the ACU075A-USB — an adapter chain on either end will introduce signal quality risk on an analog path.
• This is a short-range unit rated to 75 feet; if your console relocation distance exceeds that, you'll need a longer-range extender from the Black Box line rather than cascading two ACU075A-USB units, which is not a validated configuration based on available evidence.

Best fit: server room and operations center deployments where a VGA-native operator console needs to move to a remote desk or secondary rack position within 75 feet, and the infrastructure budget favors reusing in-place CATx rather than pulling new cable.
