RS-485 (also known as EIA-485) is a serial communication protocol used for data transfer between different devices. The data transmitted by RS-485 uses differential signaling, a method commonly used in electronic signal transmission where data is communicated as the difference between two complementary signals. RS-485 supports multi-point communication, making it suitable for applications where communication between multiple devices is needed. RS-485 can operate in half-duplex or full-duplex communication modes. In half-duplex mode, the transmission direction is switchable, allowing only one device to send data at a time. In full-duplex mode, simultaneous two-way communication is possible. RS-485 is widely used in industrial control systems, automation systems, building automation, energy management systems, and other fields that require reliable and long-distance transmission.

In terms of hardware, to ensure the accuracy of transmission, termination resistors are usually installed at both ends of the RS-485 communication line. This helps eliminate signal reflections and improve transmission stability.
