2x1 18G KVM Extender over HDBaseT
HDBT-HUUB321-70M
The ABtUS 2x1 18G KVM Extender over HDBaseT includes a transmitter (TX) and a receiver (RX), enabling high-quality video transmission over a single CAT6A cable. It supports distances of up to 40m at 4K@60Hz and 70m at 4K@30Hz. Additional features include audio pass-through, two-way IR, USB extension, and RS232 pass-through. The 24V PoC (Power over Cable) functionality allows the TX and RX to power each other, requiring only one power adapter for the entire system—either the TX or RX needs to be powered.
● 18Gbps high bandwidth, HDMI V2.0.
● HDMI and USB-C video resolution up to 4K@60Hz 4:4:4, HDR10, Dolby Vision.
● Supports to transmit up to 40m at 4K@60Hz or 70m at 4K@30Hz, with HDCP 2.2.
● Controlled by button on the front panel, GUI (via TCP/IP) and RS232.
● Two-way IR and RS232 pass-through.
● Supports audio separation for PCM 2.0, and audio pass-through.
● Supports two-way 24V PoC.
● Provides HDMI loop out.
