Introduction to RS232 signals and some common uses

RS232 is a widely used serial communication interface standard, which is still widely used in many industrial and professional applications due to its simplicity, stability, and strong compatibility. Mainly used for data transmission between computers and various external devices. The RS232 interface is commonly used to connect modems, printers, mice, industrial control devices, and embedded systems.

Introduction to RS232 signals

Single-ended signal: RS232 uses single-ended signal to transmit data, that is, one signal line is used for data transmission. Signal lines are usually divided into the transmitter (Tx), the receiver (Rx), the ground line (GND), etc.

Voltage level: RS232 uses a bipolar signal standard, which usually stipulates that the positive level (logic "1") is a negative voltage and the negative level (logic "0") is a positive voltage. The typical voltage range is -15V to +15V.

Communication rate: RS232 supports a variety of communication rates, including 9600 bps, 19200 bps, 38400 bps, etc., which can be configured according to communication requirements.

Asynchronous communication: RS232 uses asynchronous communication, that is, no external clock signal is required for data transmission. Each data character contains a start bit, a data bit, a stop bit, and a possible check bit.
