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.
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.
ANSI TIA/EIA-422 and TIA/EIA-485 standards, commonly known as RS-422 and RS-485, respectively, specify balanced data-transmission schemes for transmitting data over long distances in noisy environments. These standards are compared, and their basic differences and similarities are discussed.
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
Understanding RS485 Standard and Working of RS485 Transceiver
2024年4月17日 · RS-485 is a balanced data transmission standard for serial communication. RS-485 facilitates the robust transmission of moderate data rates across long distances in multipoint communication applications.
What is RS485 - RS485 Communication Guide [2025]
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.
All about RS485 – How RS485 Works and How to Implement RS485 …
2021年3月18日 · In RS485 standard, data is transmitted via two wires twisted together also referred to as “Twisted Pair Cable”. The twisted pairs in RS485 give immunity against electrical noise, making RS485 viable in electrically noisy environments. RS485 at its core with 2 wires allows half-duplex data transmission.
What is RS 485? - Digi-Key Electronics
2023年12月27日 · The RS-485 standard defines that devices must transmit data using differential signaling over a twisted pair of impedance-matched signal wires A and B. The communication partners encode bits as the voltage difference between the two wires rather than a single wire and a common ground.
RS485 conveys data differentially over a terminated twisted pair, permitting up to 10Mbps data rates. The standard specifies electrical characteristics of a driver and receiver, and does not specify any data protocol or connectors.
RS-485 - MultiTech
RS-485, also known as TIA-485 or EIA-485, is a serial communication standard that defines the electrical and functional characteristics of a balanced data transmission system. It’s commonly used for long-distance communication in industrial and commercial applications where robustness, noise immunity, and multi-drop capabilities are important.
