The multi-serial server is a converter between multiple asynchronous serial ports RS232/422/485 and Ethernet. It is an independent smart device with CPU, embedded operating system and complete TCP/IP protocol stack. Complete bidirectional transparent data transmission between RS232/422/485 and Ethernet, and allow multiple RS232/422/485 serial port devices to access the network immediately.
RS232/RS485 devices are immediately upgraded to devices with Ethernet interfaces. A solution for small and medium-sized engineering projects using a serial port server as a bridge between the upper and lower computers. Through this solution, the data collected by the lower computer can be transmitted through Ethernet. The monitoring center and each control terminal receive data through the Ethernet transmission protocol, iot gateway industrial which improves the data transmission rate and security, and also greatly improves the real-time monitoring efficiency of the factory.
Simply speaking, the multi-serial port server is suitable for use in the environment where multiple asynchronous serial ports need to transmit data with the Ethernet interface at the same time.
For example, the centralized power supply monitoring system monitors the operating parameters of distributed switching power supplies, air conditioners, oil generators, batteries, high and low voltage power distribution and other equipment in industrial and civil buildings, diagnoses and handles faults, and analyzes relevant data. Record and analyze in real time, realize centralized monitoring, maintenance and centralized management of equipment with few or no people on duty.
Use of serial communication
Serial port is a kind of interface. The purpose is very clear in the title, which is “communication”. Just like calling, sending QQ, and sending WeChat, the sending method is also very similar. Whatever data is sent by the sender, the receiver will receive the data. This is called transparent transmission, iot sensor module or “transparent transmission” for short. The difference is that calling and sending WeChat is a behavior between people, while serial communication is a behavior between machines.
The official explanation of serial port communication is: the communication method of sending and receiving bytes by the serial port bit by bit. It can be used for many purposes, such as connecting shopping mall access control, printers or medical equipment, and it can also be connected to industrial instruments. For the improvement of drive and connection, the transmission length or speed of RS-232 in practical applications often exceeds the standard value.
