About the Crestron USB-EXT-2 USB over Category Cable Extender, Local and Remote
The Crestron USB-EXT-2 is a professional-grade extender system designed to overcome the inherent distance limitations of the Universal Serial Bus (USB) standard, enabling the reliable operation of USB devices up to 150 feet (approximately 46 meters) away from a host computer. This solution is critical in integrated systems for corporate, educational, and government environments where a computer located in a secure equipment rack must interface with peripherals—such as touchscreens, document cameras, keyboards, mice, or smart card readers—positioned at a lectern, in a conference table, or on a wall. The system operates as a transmitter and receiver pair, converting the USB signals for transmission over a single, affordable Category 5e/6/6a cable (standard Ethernet cabling), thereby leveraging the existing structured wiring infrastructure of a building to simplify installation and reduce costs compared to specialized USB cabling.
The extender is engineered for full plug-and-play compatibility and transparent operation; once connected, the host computer recognizes the remotely connected USB device as if it were directly plugged in, without requiring any special drivers or software on the host. The "Local and Remote" designation indicates the kit includes both the transmitter unit (which connects to the host computer's USB port) and the receiver unit (which provides USB ports for the peripheral devices). It typically supports USB 2.0 specifications, ensuring adequate bandwidth for human interface devices (HID), audio class devices, and moderate-speed data transfer, while maintaining signal integrity and timing over the extended distance. Advanced error correction and signal conditioning within the units ensure a stable connection, preventing data corruption or device disconnections that can plague simpler, passive extension solutions.
Built with the reliability expected from commercial AV infrastructure, the units feature compact, rugged metal enclosures designed for discreet installation. They are often powered via the USB connection itself or an included external power supply for the receiver unit to ensure consistent voltage to connected peripherals. The Crestron USB-EXT-2 solves a fundamental connectivity challenge in modern system design, enabling flexible room layouts and centralized equipment management by decoupling the location of the computer from the user's interface devices. This functionality is essential for creating streamlined, professional, and user-friendly technology spaces where the complexity of the system is hidden, and the user experience is simple and direct.
