80817011 application field and working principle

80817011, also known as "serial bus interface" or "RS-232 interface", is a computer serial port standard designed to facilitate the connection of peripheral devices. It is widely used in PC communication and digital instrument control. This article will discuss the application field and working principle of 80817011.

Application field

80817011 has been around for a long time, and it has become the standard serial port used in most computers. It is mainly used for data communication between various electronic devices such as PCs, printers, modems, and data communication between data terminals and the serial port of an external device such as a mainframe computer.

Due to its high compatibility, 80817011 is widely used in the communication between various electronic devices. It is widely used in embedded systems to communicate with other devices, such as network cards, and digital cameras. It is also used to connect embedded systems such as ATMs, factory automation systems, and many other devices.

In addition, 80817011 is used in the fields of computer diagnosis, remote monitoring, industrial control, medical instrumentation, home automation, FA industry, data acquisition and control, and scientific instrumentation.

Working principle

The working principle of 80817011 is mainly based on the exchange of data between two devices using the 8-bit transmission of asynchronous communication. In the process of data communication, the serial communication procedure includes three stages: data transmission, data reception and line control.

80817011 works in the following manner. Both devices in the communication system exchange data by transmitting one byte at a time over a single line. The transmitting device sends a start bit followed by 8 data bits, and then sends a stop bit. When the transmitting device transmits a byte of data, the receiving device will recognize the start bit, and then receive the 8 data bits. After that, the receiving device will receive the stop bit and then send a response signal.

In this way, the data of both systems can be transmitted and received without a data bus. During the data communication, the serial communication procedure enhances the reliability of the data transmission. It can automatically detect error signals, stop transmission and indicate that an error has occurred. Through the use of parity bits, the accuracy of data transmission can be further improved.

In conclusion, 80817011 has a wide range of applications and is widely used in all kinds of electronic devices. It can be used to facilitate the connection of peripheral devices and improve the efficiency of data communication.
