HD6400K
8K HDMI™ over HDBaseT Extender, up to 150 m
8K HDMI™ over HDBaseT Extension
HD6400K is a high-performance, long-reach HDBaseT extender designed for HDMI, RS-232 and IR signal transmission over a single twisted-pair copper cable. The transmitter converts the HDMI and control signals into HDBaseT for long-distance delivery, while the receiver restores them to the original HDMI and control interfaces at the display end.
The system supports transmission distances of up to 90 m / 295 ft for 8K@30Hz 4:4:4 and 4K@120Hz 4:4:4, 120 m / 394 ft for 4K@60Hz 4:4:4, and 150 m / 492 ft for 1080p over CAT6 cable.
For best reliability, use a direct-interconnection network cable layout. Do not use a crossover cable. A surge protection system is also recommended to protect the extender and connected equipment.
