Description: The so-called " serial communication means between the peripherals and the computer using a data signal line (another ground, and may also need to control lines), the data in a data signal line A A transmission, each bit data occupy a fixed length of time. Fewer data lines used by this communication, the communication cost can be saved in long-distance communications. In simple applications, just to have three lines to complete the communication are second foot RXD Pin 3 TXD pin 5 GND. Interface: serial communication between the microcontroller serial communication level logic defined+15V (high level 1)-15V (low 0) microcontroller with 5V, 0V to represent 1,0 they of between level conversion must be completed. communication. The most commonly used is the circuit composed of MAX232 chip.
