In many industrial and commercial applications, traditional serial communication interfaces (such as RS232 and RS485) are still widely used. However, with the popularity of wireless networks and the rapid development of the Internet of Things (IoT), how to connect these traditional serial interface devices to modern networks has become an important demand. WiFi serial port servers have emerged to provide a solution for converting serial interfaces to WiFi network communications.
RS232/RS485 serial port communication introduction
Working principle of WiFi serial port servers
The basic function of WiFi serial port servers is to transmit serial communication data through WiFi networks. Its working principle includes the following steps:
Serial data reception: WiFi serial port servers receive data from serial devices through their serial ports (such as RS232 and RS485).
Data encapsulation: The received serial data is encapsulated into TCP/IP or UDP data packets.
WiFi transmission: The encapsulated data packets are transmitted to the specified network address (such as a server or another computer) through the WiFi module.
Data decapsulation: At the receiving end (such as a computer or server), the data packets are decapsulated and restored to the original serial data.
Features
Wireless communication: Wireless transmission of serial data is achieved through WiFi networks, getting rid of the limitations of traditional wired connections.
Multi-protocol support: supports multiple communication protocols, such as TCP/IP, UDP, and provides flexible data transmission methods.
Remote management: WiFi serial port servers can be remotely configured and managed through the network, which facilitates device maintenance and upgrades.
Multi-serial port support: Some WiFi serial port servers support multiple serial ports, which are suitable for application scenarios that require multiple device connections.
