How It Works:
The Gefen GF-EXT-HDK-HBT2 uses HDBaseT 2.0 technology to transmit uncompressed ultra-high-definition HDMI video and USB signals over a single CAT cable, extending high-resolution content and peripheral control up to 330ft (100m). This eliminates the need for multiple cables, reducing installation complexity while preserving signal integrity.
Bi-directional Power over HDBaseT (PoH+) supplies power through the same cable, simplifying setup and reducing cable clutter. The device also supports audio de-embedding and eARC, enabling users to route audio flexibly from HDMI sources to external audio systems.
With advanced EDID management and low-latency signal processing, the extender ensures consistent display compatibility and fast, natural input response for KVM control. Its robust metal enclosure, heavy-duty housing, multi-region power supply, and reinforced connectors ensure reliable operation in demanding professional environments, such as control rooms and production suites.
Ideal for:
• Broadcast and Production Environments
• Corporate and Control Centers
• Healthcare and Medical Imaging
• Education and Training Facilities
• Use Case Examples
• Problems It Solves
System Requirements:
• HDMI Source and Display: Compatible HDMI sources and displays capable of handling 8K@60Hz and 4K@120Hz signals, leveraging the extender's full 40Gbps HDMI 2.1 bandwidth support.
• USB Devices: USB 2.0 compatible peripherals such as keyboards, mice, and touchscreens, supported by the integrated USB 2.0 KVM extension.
• Network Cabling: CAT6/CAT6a twisted pair cabling suitable for HDBaseT 2.0 transmission up to 330ft; shielded CAT6a or better is a best-practice recommendation
• Power: 12V/3A DC locking power supply (multi-region supported), with bi-directional PoH+ available between sender and receiver over the HDBaseT link.
• Control Systems: RS-232 integration via the 3-terminal Euroblock connector on sender and receiver for serial-based control where required.
• Firmware: USB Type-C service port on sender and receiver for firmware updates via a connected PC.
