RS485 Description

Short technical summary and product information.

The RS485 standard, also known as TIA-485(-A) or EIA-485, defines the electrical characteristics for serial communication drivers and receivers. This standard is jointly published by the Telecommunications Industry Association and Electronic Industries Alliance (TIA/EIA).

RS-485 utilizes balanced signaling over a twisted pair cable, making it suitable for long distances and electrically noisy environments. It supports various network topologies, including point-to-point, multi-dropped, and multi-point configurations. The standard specifies different receiver levels for binary 1 (OFF) and binary 0 (ON), with thresholds of less than -200 mV and greater than +200 mV, respectively.

This standard can be used with data rates up to 10 Mbit/s and supports at least 32 unit loads. Its robust characteristics make RS-485 a popular choice for industrial control systems and other applications requiring reliable serial communication.
