RS-485 Protocol
RS-485 is a differential signaling standard for serial communication that enables long-distance data transmission over twisted-pair cables. Unlike single-ended signals like UART, RS-485 uses differential signaling, which provides excellent noise immunity and allows communication over distances up to 1,200 meters (4,000 feet).
RS-485 supports multi-point networks, allowing multiple devices to communicate on a single bus. The protocol uses half-duplex communication, meaning data can flow in both directions but not simultaneously. RS-485 is widely used in industrial automation, building automation, process control, and other applications requiring reliable long-distance communication.
Our USB host adapters provide RS-485 support with robust common-mode voltage handling, enabling you to develop, test, and debug RS-485 networks in industrial and commercial applications.
