RS-485 - Wikipedia
RS-485, also known as TIA-485 (-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced, and multipoint systems are supported.
RS485 Communication Protocol: Basics, Working Principle
What is RS485? RS485 is a serial communication protocol. It is one of the most widely used communication protocols, especially in noisy industrial areas. Two devices can communicate with each other over a long distance (up to 1200m) using RS485 communication. Unlike RS232, RS485 has a 10 mbit/s data transfer rate.

2024年11月8日 · RS485, also known as EIA-485, is a standard that defines the electrical characteristics of drivers and receivers for balanced data transmission. Unlike RS232, which connects only two devices, RS485 supports multiple devices on a single communication line.
2023年9月12日 · RS-485 is a communication standard for transmitting and receiving data over long distances between devices. It uses a balanced pair of wires to send signals and can communicate at high speeds over distances up to 1200 meters. The purpose of RS-485 is to provide a reliable and robust communication protocol for industrial and
RS-485 is an electrical-only standard. In contrast to complete interface standards, which define the functional, mechanical, and electrical specifications, RS-485 only defines the electrical characteristics of drivers and receivers that could be used to implement a balanced multipoint transmission line.
