In the era of rapid development of industrial automation and IoT, the interconnection of equipment has become the key to improving production efficiency and management level. For devices still relying on traditional serial port communication, how to achieve seamless connection with modern network systems has become an urgent problem to be solved. The RS485 to Ethernet converter is the perfect solution to this problem.

1. Basic concept of RS485 to ethernet Convertor

RS485 to ethernet Convertor, as the name suggests, is a device that can convert serial communication interfaces such as RS-232, RS-485, etc. into Ethernet or other network interfaces. It has a built-in processor and communication chip that can package serial data into IP packets and transmit them to the target device over the network. At the same time, it can also convert received network data into serial data and send it to the connected serial device. This process achieves bidirectional transparent transmission of data, allowing traditional serial devices to easily access modern network systems.

2. Operating principle of RS485 to ethernet Convertor

The working principle of RS485 to ethernet Convertor is relatively simple but very efficient. When the serial device sends data, the RS485 to ethernet Convertor will capture these data and package them according to the preset network protocol such as TCP/IP, MQTT, etc. Then, these data packets will be sent to the specified network address, and the receiving end's RS485 to ethernet Convertor will unpack them and restore them to the original serial port data. Conversely, when network data arrives, the RS485 to Ethernet converter will also perform corresponding processing to ensure that the data is transmitted to the serial device accurately and without error.
