Black Box EMD100USB

Overview

The Black Box EMD100USB is a KVM over IP USB extender designed to extend full-speed USB 2.0 connectivity up to 328 feet (100 meters) using a single CATx cable or a standard Ethernet network. It allows users to relocate keyboards, mice, touchscreens, and storage drives without losing performance, supporting data rates up to 480 Mbps while maintaining backward compatibility with USB 1.1 devices. This makes it an excellent solution for environments where computers need to be secured in racks but peripherals must remain accessible locally.

Key features

• Extends USB 2.0 signals over long distances using existing copper cabling or Ethernet LAN, simplifying installation and reducing cable clutter.
• Supports data rates up to 480 Mbps, ensuring smooth operation of high-speed USB peripherals alongside legacy USB 1.1 devices.
• Four USB Type A ports on the receiver allow multiple peripherals to connect simultaneously, enhancing workspace flexibility.
• Each USB port delivers up to 600 mA of power, often removing the need for additional power adapters for connected devices.
• Integrates seamlessly with Emerald KVM systems to enable USB device sharing, allowing multiple users to collaborate without unplugging devices.
• Designed for demanding environments such as industrial control rooms, manufacturing floors, classrooms, and corporate meeting spaces.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
