HE02U-4K6G is a high-performance HDMI® KVM extender powered by the latest HDBaseT 3.0 technology. It is specifically designed for industrial control environments where zero latency and ultra-high-definition visuals are critical. Using just a single CAT6a (or higher) cable, you can transmit uncompressed 4K60Hz signals up to 100 meters. Equipped with the Valens Stello VS3000 chipset, this solution supports high-speed USB 2.0 and integrates bidirectional RS-232, audio transmission, and Ethernet extension. It is the ideal KVM solution for industrial control, broadcast centers, medical imaging, and large conference rooms.
Supports 4K60Hz 4:4:4 resolution and is fully compliant with HDMI® 2.0 and HDCP 2.2 standards, providing exceptional clarity and a highly responsive user experience.
Utilizing industry-standard HDBaseT™ technology, we ensure your 4K video remains uncompressed and lag-free over long distances.
The receiver (RX) features 4 USB 2.0 ports to connect keyboards, mice, flash drives, or even USB cameras and touchscreens.
Supports HDMI® audio as well as 3.5mm analog audio input/output, making it easy to connect external speakers or sound systems.
Includes bidirectional RS-232 for control signals and an Ethernet port for seamless network device connectivity.
The Transmitter (TX) includes a built-in HDMI® Loop-out port, allowing for easy local monitoring. This design enables installers to verify video signals on-site and troubleshoot effectively without the need to plug or unplug cables.

To ensure your projects run smoothly, SC&T has conducted rigorous performance testing across various cable brands and series. We provide these detailed results so you can accurately evaluate the feasibility of your setup before installation begins.
For extra peace of mind, you can also consult the HDBaseT officially certified cable list to help guarantee a reliable and fail-safe installation.
HDBaseT 3.0 represents the most powerful audiovisual transmission standard currently available on the market. Compared to traditional IP-based transmission or other compression technologies, HDBaseT 3.0 delivers:
A: The most critical difference is the bandwidth. HDBaseT 3.0 increases bandwidth from 10 Gbps to 18 Gbps, enabling the transmission of uncompressed 4K60Hz 4:4:4 signals. While this ensures superior image quality, it also requires higher-grade network cabling to maintain stability.
A: No. HDBaseT 3.0 technology provides a Zero Latency environment. Even at the maximum distance of 100 m, mouse dragging and keyboard input remain as responsive as if they were connected directly to the computer. This makes it an ideal solution for gaming or medical workstations that demand precision.
A: To ensure stable 4K60Hz transmission over 100 m, we strongly recommend using HDBaseT-certified CAT6a U/FTP cables or higher. For the best results, please refer to the specific cable models tested and verified by SC&T.
A: No. HDBaseT utilizes a proprietary transmission protocol. It requires a direct, point-to-point connection between the Transmitter (TX) and Receiver (RX) using a network cable and cannot be integrated into standard IP network switches.
A: Yes. The HE02U-4K6G supports backward compatibility and features HDMI pass-through, requiring no additional configuration.
A: Yes. The HE02U-4K6G supports the USB 2.0 standard, making it compatible with most USB cameras, flash drives, and Human Interface Devices (HID).
A: Yes. The product features CEC Passthrough, enabling remote control across connected devices. For example, you can conveniently power your source equipment on or off from the receiver side using your existing remote.
A: No. The HE02U-4K6G does not support PoH/PoC functions. Both the Transmitter and Receiver units require their own power supply to operate.
A: HDBaseT 3.0 is highly sensitive to cable quality and environmental interference. Please ensure the network cable is undamaged and kept away from high-voltage power lines. If the issue persists, please consult our "HDBaseT Installation & Troubleshooting Guide" available on the official website.
