Talking about the function, classification and working principle of OTG data line

图片
  What is the OTG line? OTG is mainly applied to the connection between various devices or mobile devices for data exchange. The development of USB technology enables computers and peripheral mobile devices to transmit various data through simple USB connections. This will lead to a situation, once the mobile phone or tablet does not have a computer, we cannot manage the data of mobile devices such as mobile phones, which brings inconvenience to users. As mobile devices such as mobile phones become more and more like computers, can we imagine that we can use mobile phones as computers? Can a U disk, USB network card, etc. be connected to the phone? The answer is yes, the OTG function is to realize that the mobile phone can be connected with USB devices such as U disk, but the mobile phone has a tiny   USB   interface, which cannot meet the needs of USB ports such as U disk. So far, the OTG data cable came into being. The role of OTG is to realize data transfer between mob...

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and...

BNC interface protocol in video output

图片
In the following, you will be presented with a set of questions and answers about the "What protocol is going on in the BNC interface video output" and the  Konnra Electronics  engineers' Q&A record, so that you can easily understand what protocol is going on in the video output of the BNC interface in the interaction. related question. The core of the problem: What protocol is going inside the BNC interface video output? Problem Description: For example, this bnc interface video output device, BNC is the signal of the H.264 protocol, it is necessary to configure the photoelectric conversion equipment between it and the camera, how to configure it? What kind of docking can it be? Answer: The BNC interface input and output is commonly referred to as the Q9 header, which is used to transmit baseband video signals. The single BNC port of the monitoring device transmits the analog composite signal. The video recorder saves the video file of the analog video signal into...
