ZY-CKH531 4K HDMI KVM Network extender is a powerful remote control and signal expansion device with 4K@30Hz Ultra high definition resolution. Composed of a transmitter, receiver, and Ethernet cable (network), it enables remote expansion of keyboard, mouse, speaker, microphone, HDMI signal, and RS232 through a single Ethernet cable or gigabit network, allowing users to operate a remote computer in front of the television.
The product supports remote power on/off function, allowing for remote control of computer on/off without the need to physically visit the computer room. The receiving end is equipped with 4 USB interfaces, which can be used to connect devices such as USB flash drives, touch screens, printers, scanners, and even USB standard definition cameras. All signals are controlled through the network. Supports bidirectional audio transmission - forward audio output and reverse microphone input, while also supporting RS232 serial port transparent transmission (baud rate 115200), compatible with HDCP 1.4 version.
Adopting high-speed ASIC technology ensures near zero latency for remote image, keyboard, and mouse operations. Supports HDMI local loop out and EDID learning function, automatically adjusts video compression rate to ensure smooth playback. The network supports one-to-one transmission and one to many transmission methods, and can be flexibly networked through gigabit switches. Plug and play, no need for any settings, widely used in high-definition conferences, remote control, industrial control, multimedia teaching and other scenarios.
💡 Core advantages:4K@30Hz Ultra high definition+remote power on/off+4 USB ports+bidirectional audio+RS232 transparent transmission+ASIC zero latency - a versatile KVM network transmission solution for remote control, multifunctional expansion, and plug and play.
