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.

2021年10月19日 · RS-485 (currently known as EIA/TIA-485) is a standard interface of the physical layer of communication, a signal transmission method, the 1st level of the OSI (Open System Interconnection) model. RS-485 has been created in order to expand the physical capabilities of RS-232 interface.

RS-485, formally known as American National Standards Institute (ANSI) Telecommunications Industry Association (TIA)/Electronic Industries Alliance (EIA)-485-A, is a balanced data transmission standard for serial communication. RS-485 allows for robust transmission of moderate data rates over long distances in multipoint

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.

2021年3月18日 · In short, RS485 is a standard defining the electrical characteristics of serial lines for use in serial communications systems. It is essentially a form of serial communication. It may sound complicated for those who don’t know what is serial communication, so here’s an explanation. In this article, we’ll go through: What is Serial Communication?

2023年12月19日 · RS485, also known as EIA-485, is a widely used communication standard in the field of industrial automation and control systems. What is rs485 - It is a serial communication protocol that allows multiple devices to communicate …

2023年12月27日 · Dive into the world of serial communication with a detailed look at RS-485. Compare it to RS-232 and understand why it's widely used in industrial settings.

2025年3月12日 · Just like it’s older brother RS232, RS485 is a form of serial communication. Think of RS485 as the younger, faster brother of RS232. What made it such an advancement over RS232 was the fact that it could transmit not only a single device to device transmission, but also a communications bus to connect multiple devices at once.

2024年4月18日 · RS-485 (also known as TIA/EIA-485) is a standard interface for physical communication. It is a form of serial communication. Typical serial communication standards are RS232 and RS485.

RS485 extends the common mode range for both drivers and receivers in the "tri-state" mode and with power off. Also, RS485 drivers are able to withstand "data collisions" (bus contention) problems and bus fault conditions.
