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.

2023年12月19日 · It enables devices to communicate and exchange data, rs485 port, facilitating tasks such as file transfers, device control, and data logging. What is RS485? RS485, also known as EIA-485, is a widely used communication standard in the field of industrial automation and control systems.

2021年3月18日 · It converts a USB port to use with RS485. Best known for the simplicity of usage it provides, it also features embedded circuits protection features such as lightning-proofing, resettable fuse, ESD protection and TVS diode. It allows for …

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.

In 1983, the Electronics Industries Association (EIA) approved a new balanced transmission standard called RS-485. Finding widespread acceptance and usage in industrial, medical, and consumer applications, RS-485 has become the industry’s interface workhorse.

RS-485 is an industrial specification that defines the electrical interface and physical layer for point-to-point communication of electrical devices. The RS-485 standard allows for long cabling distances in electrically noisy environments and can support multiple devices on the same bus.

Section 2 and Section 4, respectively, discuss the basic design and operation of the RS-485 driver and receiver. This document also covers receiver failsafe operation, transceiver power dissipation, transient protection, and more.
