WebEach RS232 driver uses inverting logic and implements a single-ended bipolar output voltage (that is, one signal that swings above and below ground). A logic high at the UART is converted by the RS232 output driver to a voltage between –7 and –12 volts, while a logic low at the UART is converted to a voltage between +7 and +12 volts. In RS-232, user data is sent as a time-series of bits. Both synchronous and asynchronous transmissions are supported by the standard. In addition to the data circuits, the standard defines a number of control circuits used to manage the connection between the DTE and DCE. Each data or control circuit only operates in one direction, that is, signaling from a DTE to the attached DCE or t… WebThere are a number of ways mechanisms are used to minimize the risks of this type of problem.
