RS485 Description

Short technical summary and product information.

The RS485 standard, also known as TIA-485(-A) or EIA-485, defines the electrical characteristics of drivers and receivers for serial communications systems. This standard supports multipoint systems over long distances and in electrically noisy environments.

 

The RS485 transceiver from 3PEAK operates according to the TIA-485-A standard, approved on March 3, 1998, and reaffirmed on December 7, 2012. It uses a balanced interconnecting cable for its physical media. The network topology supports point-to-point, multi-dropped, and multi-point configurations, allowing for at least 32 unit loads.

 

Key operational characteristics include different receiver levels for binary 1 (OFF) and binary 0 (ON), defined by voltage thresholds. The available signals are A, B, and C. While the maximum distance is not specified, RS-485 is generally accepted for data rates up to 10 Mbit/s, making it suitable for industrial control systems and similar applications requiring robust serial communication.
