Working Principles

The MAX3082CSA+T is an RS-485/RS-422 transceiver that enables bidirectional communication over long distances. It uses differential signaling to achieve noise immunity and high data rates. The driver section converts the logic-level signals into balanced differential voltages, while the receiver section converts the differential voltages back into logic-level signals. The transceiver operates in half-duplex mode, allowing transmission and reception on a single pair of wires.
