Tx & Rx, Host & Device
The LinkU USB-C 4K60 Extender Kit handles both video transmission (Tx/Rx) and USB 2.0 extension (Host/Device). One compact kit, multiple functionalities—designed to simplify your AV setup.
Power Over Cable (PoC)
Powering your installation couldn’t be easier. Just plug in one power supply, and the other unit is powered automatically via PoC, reducing cable clutter and installation time.
Intelligent EDID Management
User-configurable EDID settings ensure reliable handshakes between Mac and PC sources and any display. Eliminate resolution mismatches and compatibility issues across mixed-device environments with full API control and remote EDID management.
HDCP 2.3 Secure Content
Full HDCP 2.3 compliance creates a secure, encrypted pipeline between source and display, supporting protected content from streaming services, Blu-ray players and corporate DRM-enabled media without signal interruption.
Designed for Fast Deployment
True plug-and-play operation with universal device compatibility. Bidirectional Power over Cable (PoC) means only one power supply is needed for the entire kit — power either unit and the other is powered automatically through the CAT cable.
