Remote control computer solution-HDMI KVM extender

        With the rapid development of science and technology, many hosts and control centers are getting farther and farther away, so how to power on and off normally at a distance of tens of meters, 100 meters, etc., and use the mouse, keyboard, microphone, earphone, HDMI display normally? The first thing we have to solve is to extend the HDMI signal to ensure that the HDMI audio and video signals of the host can be synchronized to the control center without loss within 100 meters; then to solve the USB signal synchronization extension problem, so that the mouse can be connected to the control center , The keyboard controls the computer; finally, it needs a synchronous extension of the power on and off signal, so that a physical switch can be connected in the control center to realize remote control on and off.

        Of course, it would be better if it supports microphone audio return and 3.5mm stereo output, so that in the control center, it is exactly like the host's local experience. There is just an HDMI KVM extender that perfectly achieves the above functions. The principle of extension is to transmit the HDMI signal and USB signal to the receiving end 100 meters away through a single CAT6 network cable. The receiving end restores the signal and turns on and off the signal. , The microphone audio signal RS232 signal is packaged and transmitted back to the transmitting end, and the transmitting end analyzes and restores the switch machine signal, microphone audio signal, etc. Here will take the HDMI KVM extender HU100 as an example to introduce the interface and connection diagram in detail.

        Through the above picture explanation, we can use the HDMI KVM extender to realize remote control of the computer without adding additional drivers, including switch machine, normal typing office, audio and video synchronization playback, microphone audio return, etc., the most important One point is that the remote control does not depend on the Internet network. The whole process is carried out through a CAT6 network cable. It is relatively safe for some places that are more confidential or inconvenient to use the network (including internal and external networks). After all, it is a single-wire physics. control.
