Working Principles

TRS3243CDW operates based on the RS-232 communication standard. It uses voltage levels to represent binary data, where positive voltages indicate logic 0 and negative voltages indicate 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, TRS3243CDW converts the internal logic levels to RS-232 voltage levels and sends them through the respective transmit data pins. On the receiving end, it receives RS-232 voltage levels and converts them back to internal logic levels for further processing.
