Working Principles

ST3241ECDR operates based on the RS-232 communication protocol. It uses voltage levels to represent binary data, with positive voltages indicating logic 0 and negative voltages representing logic 1. The transceiver converts the logic levels between the RS-232 standard and the internal logic levels of the connected devices.

When transmitting data, the IC converts the internal logic levels into RS-232 compatible signals and sends them through the respective transmitter channels. On the receiving side, the transceiver receives RS-232 signals and converts them back to the internal logic levels for further processing by the connected devices.
