KVM extender Black Box ACU1700A — HDMI & USB, wired, 100 m range, transmitter and receiver

Black Box ACU1700A is a wired KVM extender kit comprising a transmitter and a receiver designed for extending HDMI video and USB keyboard/mouse control up to 100 meters over a single copper cable. Both transmitter and receiver provide local HDMI ports for video passthrough. The transmitter is compact and powered by a 12 V AC adapter, making the kit suitable for installations where the user workstation must be separated from the host computer while retaining full keyboard, video and mouse functionality.

Advantages

The ACU1700A kit delivers reliable HDMI video extension and USB HID support over a long-range wired connection without requiring network infrastructure. Its separate transmitter and receiver units allow placement flexibility and support local HDMI outputs on both ends for monitoring or direct connection. The compact transmitter size simplifies mounting in constrained spaces and the standard 12 V power supply ensures compatibility with common power setups.

Suitable for

• Remote desktop control stations where the computer must remain in a secure or climate-controlled location
• Control rooms and broadcast facilities requiring stable HDMI video and USB keyboard/mouse extension
• Secure workstation setups that separate user access from host hardware
• Work environments where a single copper run up to 100 m is preferred over networked KVM solutions

Key specifications

• Connection type: wired KVM extender kit with separate transmitter and receiver units
• Video interface: HDMI on transmitter and receiver local ports
• USB support: keyboard and mouse (USB HID) on the receiver
• Maximum extension distance: up to 100 m over copper cable

How to use

Connect the host computer's HDMI output to the transmitter's HDMI input and plug the transmitter into the 12 V power adapter. Run the specified copper cable from the transmitter to the receiver up to 100 m. Connect the receiver's HDMI output to the remote monitor and attach a USB keyboard and mouse to the receiver's USB ports. Power on both units and verify video and input signals; the devices operate transparently so no additional drivers are typically required for standard USB HID devices.

Usage recommendations

For best results, use high-quality shielded copper cable of the recommended type and maintain a clean, direct cable run without excessive bends. Place the transmitter in a ventilated area and verify compatibility of connected monitors and USB peripherals. In secure environments, locate the host computer in the controlled zone and run the extender cable to the user station to maintain equipment separation while preserving full HDMI and USB functionality.
