How does the serial port server handle the data exchange between the Ethernet interface and the rs232 and ra485 interfaces?

The serial server processes various data, maps the Ethernet interface of the TCP/IP protocol into a standard serial port, processes the serial data flow of the serial device, converts the format, and controls sending and receiving, making it a data frame that can be transmitted by the Ethernet, and judging the Ethernet Data frame, converted into a serial data transfer response to the serial device.
The system configures relevant network audio and video interface devices at each node to ensure the connection of audio and video signals. At the same time, each interface machine has a programmable control interface (RS-232, RS-485, IR infrared) to control the surrounding equipment. The control of each module can work independently, which means that the control failure of a module during the period will not affect the operation of the entire system, only the faulty node needs to be dealt with, which ensures the stable operation of the entire system and facilitates system maintenance.
Find the existing problems in time and eliminate them immediately. The system not only displays the corresponding parameters through the display screen. It should also communicate data through its own communication interface (RS-232 or RS-485 serial port). The original substations are generally managed by local computers without networking. Using RS serial port communication can meet the requirements. Now due to the gradual development of industrial Ethernet on the national grid.
