Working Principles

The SP483CN-L is designed to facilitate reliable communication in RS-485 networks. It operates by converting the electrical signals from the driver into a balanced differential voltage on the transmission line, allowing for noise-immune data transmission. The receiver section converts the differential voltage back into logic levels for further processing.
