Understanding RS-485 Communication - Inst Tools
RS-485 communication involves a driver that produces signals and a receiver that detects them. The signal is a voltage change across a load as low as 1.5 volts differential from a driver, with a receiver detecting a differential voltage as minute as 200 millivolts.
communication. RS-485 allows for robust transmission of moderate data rates over long distances in multipoint communication applications, such as factory and building automation, motor control, and other field bus applications. The RS-485 standard only specifies the electrical characteristics of drivers and receivers; it does not specify a ...
The majority of RS-485 applications implement half-duplex (two-wire) communication. Full-duplex communication requires two signal pairs (four-wire), and facilitates higher throughput by allowing nodes to transmit and receive data simultaneously. Modern transceiver designs allow hundreds of nodes to connect to the bus.
