Black Box ACU075A-PS2 Short-Range PS/2 VGA KVM Extender

Overview

The Black Box ACU075A-PS2 is a short-range KVM extender designed to push VGA video and PS/2 keyboard and mouse signals up to 75 feet from the host computer. If your deployment requires a console or operator workstation to sit at a distance from the actual server or workstation — behind a wall, in an adjacent rack room, or across a control desk — the ACU075A-PS2 provides a straightforward cabling solution without requiring additional infrastructure beyond standard cable runs.

This type of extender is a practical fit for environments where the operator position cannot be co-located with the computing hardware: broadcast control rooms, industrial control stations, secure server rooms with restricted physical access, or AV integration racks where the host system is rack-mounted but the display and input peripherals need to be at a distance. The PS/2 interface means the ACU075A-PS2 is targeted at legacy or purpose-built hardware that ships with PS/2 keyboard and mouse ports rather than USB — a consideration to confirm before specifying this unit.

Key Features

• 75-Foot Extension Range: Moves your VGA console up to 75 ft from the host — enough to span a typical server room or place a control station outside a restricted equipment space, without signal amplification equipment.
• PS/2 Keyboard and Mouse Support: Passes PS/2 HID signals alongside VGA video, keeping the solution self-contained for systems that use PS/2 ports. Verify your host and peripheral compatibility before ordering — USB-only systems require a different extender model.
• VGA Video Extension: Extends standard VGA output, making the ACU075A-PS2 applicable to a wide range of legacy and purpose-built computing hardware still in active use across industrial, government, and broadcast environments.
• Compact Black Enclosure: The black form factor is designed for unobtrusive installation at a console position or within a rack environment where aesthetics or space constraints are a factor.

Integration and Compatibility

The ACU075A-PS2 (often searched as ACU075A PS2) is intended for direct point-to-point extension of a single VGA and PS/2 console. It is not a KVM switch and does not support multi-host or multi-user configurations. Confirm that both the host system and the target peripherals use PS/2 connectors — this is the primary compatibility gate. For USB-based keyboards and mice, or for DisplayPort and HDMI video sources, a different extender in the KVM extender category will be the correct fit. If your project involves multiple workstations or requires centralized console switching, review the broader KVM switches lineup for multi-port options. For any pre-sales configuration questions, in-house security and AV expertise is available to help match extender specs to your specific cabling and hardware environment.

Frequently Asked Questions

Q: What is the maximum extension distance of the ACU075A-PS2?

A: The ACU075A-PS2 supports a maximum extension distance of 75 feet for VGA video and PS/2 keyboard and mouse signals.

Q: Does the ACU075A-PS2 support USB keyboards and mice?

A: No. The ACU075A-PS2 is designed for PS/2 keyboard and mouse connections. If your peripherals use USB, you will need a different KVM extender model that supports USB HID.

Q: What video interface does the ACU075A-PS2 extend?

A: The ACU075A-PS2 extends VGA video signals. It is not compatible with HDMI, DisplayPort, or DVI sources.

Q: Is the ACU075A-PS2 a KVM switch or a point-to-point extender?

A: It is a point-to-point extender — it connects one host to one remote console. It does not support switching between multiple hosts or multiple users.

Q: What type of cabling does the ACU075A-PS2 use between local and remote units?

A: Based on available product data, specific cabling type between local and remote units is not confirmed in current evidence. Contact pre-sales for cabling requirements before finalizing your installation plan.

The ACU075A-PS2 occupies a specific niche in KVM infrastructure: short-range VGA and PS/2 extension at 75 feet, which is exactly what you need when the server is physically separated from the operator console by a wall or rack room — and the host system still uses PS/2. It is a narrow-fit product, but in the right scenario it eliminates the need for long cable runs directly from the host or for a full KVM-over-IP deployment when you simply do not need remote access across a network.

Technical Highlights:

• 75-Ft PS/2 + VGA Extension: Moves the full console — display, keyboard, and mouse — 75 feet from the host without signal conditioning hardware or network infrastructure between them.
• PS/2 HID Support: Passes keyboard and mouse data over the PS/2 protocol, which remains in active use on purpose-built industrial controllers, legacy government workstations, and certain embedded computing platforms where USB was never implemented.
• VGA Interface: VGA remains the output standard on a range of rack-mount servers, KVM drawers, and industrial HMI panels — the ACU075A-PS2 fits directly into these environments without adapter chains.

Deployment Considerations:

• Verify PS/2 availability on both host and peripherals before specifying this unit — most modern peripherals and many current-generation servers have dropped PS/2 entirely, making this a legacy-hardware-specific solution.
• At 75 feet, this is a short-range unit by KVM extender standards. If your console separation exceeds that distance, you will need a longer-range extender or a KVM-over-IP solution — do not assume this unit will perform acceptably beyond its rated distance.

The ACU075A-PS2 is best suited to controlled-access server rooms, broadcast equipment racks, and industrial control environments where PS/2 hardware is still in rotation and the operator position sits within 75 feet of the host — a deployment profile where a full IP-based KVM is overbuilt and unnecessary.
