Click the blue text / to follow us Serial Communication and Parallel Communication In communication and computer science, serial communication is a general concept that refers to all serial communication protocols, such as RS232, RS422, RS485, USB, I2C, SPI, etc. Serial communication refers to a communication method that transmits data bit by bit using only … Read more
Overview of RS232 The RS-232 interface complies with the serial data communication interface standard established by the Electronic Industries Alliance (EIA). The original designation is EIA-RS-232 (abbreviated as 232, RS232). It is widely used for external connections of computer serial interfaces, including connection cables, as well as mechanical, electrical, signal, and transmission processes. The RS-232-C … Read more

RS232 and RS485 have always been common interfaces in low-voltage applications. Many people mention the differences between them, so today let’s explore them together. 1. Physical Structure of the Interfaces 1. RS232 Interface: One of the computer communication interfaces, the RS-232 interface typically appears in the form of 9 pins (DB-9) or 25 pins (DB-25). … Read more
Data transmission between computers or between a computer and a terminal can be achieved using serial communication and parallel communication. Due to the advantages of serial communication, such as fewer lines and lower costs, especially in long-distance transmission, it has been widely adopted to avoid inconsistencies in multiple line characteristics. In serial communication, both parties … Read more
Digital power modules utilize various communication protocols such as I2C, SPI, CAN, and UART, as well as interaction protocols based on these, such as CANopen, SAE 1939, SMbus, PMbus, and Modbus.This article simulates a Q&A regarding knowledge related to UART communication. Question 1: What are the characteristics of UART communication? Answer: Asynchronous communication, low cost, … Read more
1. Basic Knowledge of RS232 Data transmission between computers or between a computer and a terminal can be achieved through two methods: serial communication and parallel communication.Serial communication is widely adopted due to its lower cost and fewer lines used, especially in remote transmission, which avoids inconsistencies in multiple line characteristics. In serial communication, both … Read more
In serial communication, both parties are required to use a standard interface, allowing different devices to connect easily for communication. The RS-232 communication standard is defined by a 25-pin interface and was widely used in early computers such as PC or XT models. However, in models after the AT series, a simplified 9-pin version is … Read more
