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.

Learn more about the RS-485 serial interface, including its various layers, implementation, best practices, and versatility in motion control applications.

Finding widespread acceptance and usage in industrial, medical, and consumer applications, RS-485 has become the industry’s interface workhorse. This application report presents design guidelines for engineers new to the RS-485 standard that can help them accomplish a robust and reliable data transmission design in the shortest time possible.

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 · The RS485 splitter has one male interface that connects to the Sensor Hub and four female interfaces that link to the sensors. Being a connector that is frequently used outdoors in severe environments, it is designed to be IP68-rated waterproof and dustproof.

Many higher-level interface standards reference RS-485 for their physical layer, such as Modicon bus (ModBus), process field bus (ProfiBus), DMX512, and others. Figure 1-1 illustrates some common interface standards.

2024年5月29日 · Introduction to RS485 Serial Interface. RS485, also known as TIA-485-A, EIA-485 or RS-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems.

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 …

The RS-485 interface, commonly referred to as "485," is a standard for serial communication widely used in industrial automation, data acquisition systems, building management systems, and various forms of device control.
