Built on the HDBaseT 2.0 Colligo platform, this KVM extender delivers pristine DVI video, USB, two-way audio, and RS-232 control over a single CAT-5e cable, extending reach up to 495 feet (150 meters). Ideal for conference rooms, classrooms, and digital signage, it combines ease of use with robust performance for reliable A/V distribution and remote device control. Designed for quick setup in existing networks, the system preserves image quality, audio clarity, and responsive control across substantial cable runs, enabling seamless collaboration and streamlined management of peripherals and displays.

• Extends DVI signals over a single CAT-5e cable up to 495 feet (150 meters) using Gefen's HDBaseT 2.0 technology. This single-cable approach reduces clutter and cost while delivering reliable high-definition video integrity across long distances. The transmitter and receiver pair are optimized for low jitter and stable performance in commercial environments, ensuring consistent color accuracy and sharp detail from source to screen in conference rooms, classrooms, and showroom settings.
• HDBaseT 2.0 Colligo platform adds USB and 2-way audio extension, plus RS-232 pass-through, enabling full KVM operation from a remote workstation. You can connect USB keyboards, mice, and peripherals at the display end and control the host computer remotely. The two-way audio path supports microphone input and line-level audio to and from sources, while RS-232 offers straightforward control of linked displays, projectors, and other AV devices from the remote location.
• KVM-ready design supports remote keyboard and mouse control with plug-and-play convenience. The extender preserves native USB performance with minimal latency, allowing smooth operation of software, presentations, and peripheral devices. It maintains robust EDID handling to keep display behavior consistent across cables, making it suitable for busy environments where reliability and ease of use are paramount.
• Single-cable installation with a compact transmitter and receiver pair delivers dependable performance across long runs while maintaining low latency for time-sensitive applications. The kit includes power adapters for both ends, enabling straightforward mounting near displays, media players, or wall installations. Built with durable construction and shielded cabling, it withstands the rigors of commercial AV deployments and reduces downtime.
• Versatile compatibility and control options, including RS-232 integration for external device control and simple deployment within existing AV infrastructures. The RS-232 channel enables control of projectors, displays, or other equipment from the host location or centralized control systems. Designed to scale with Gefen’s HDBaseT ecosystem, it supports growing multi-room or multi-zone configurations for education, corporate, and retail environments.

How to install Gefen DVI KVM HDBaseT 2.0 Extender

To install, connect the DVI source to the transmitter (TX) and the DVI display to the receiver (RX). Run a single CAT-5e cable between TX and RX, ensuring the cable is within the supported distance for HDBaseT 2.0. Attach USB devices (keyboard, mouse, or peripherals) at the TX or RX ends as needed, and connect the RS-232 line if you require external device control. Apply power to both the TX and RX units using the supplied adapters, then power on the source and display. Verify EDID negotiation and test the KVM connection by moving the cursor between local and remote workstations, adjusting audio, and sending commands through RS-232 to confirm remote control functionality. For best results, keep runs clear of excessive interference and use shielded CAT-5e cables rated for AV applications.

Frequently asked questions

• What is the maximum extension distance? Up to 495 feet (150 meters) over a single CAT-5e cable using HDBaseT 2.0. Actual performance can vary with cable quality, environment, and interference.
• What signals are extended? DVI video, USB peripherals (keyboard, mouse, and select devices), 2-way audio, and RS-232 control are extended through the HDBaseT link, enabling complete KVM and peripheral accessibility from the remote end.
• Is software required? No software drivers are required. The system is designed to be plug-and-play, with automatic EDID handling and standard USB signaling to minimize setup time.
