Typically, we use serial ports for direct broadcasting and switching control of video servers, recorders, and switchboards, mainly utilizing RS-232, RS-422, and RS-485 interfaces. Below we will discuss the serial port interface standards, usage, and external plugins and cables. The RS-232, RS-422, and RS-485 standards only specify the electrical characteristics of the interfaces, without involving … Read more
RS-232, RS-485, and RS-422 often encounter various serial communication issues during on-site debugging, such as communication connection problems between different ports like RS-232, RS-485, and RS-422. Typically, conversion between RS-485 and RS-422 is quite convenient. However, when communicating between RS-232 and RS-422 ports, if there are no other conversion methods available on-site, and mailing could … Read more
