‖ System Learning Life is like a marathon; sometimes you need to pause and take a breather to go further. In this issue, we will discuss what RS232 is, a term frequently heard in the industry, especially in the industrial control sector. What is RS232? It is a form of serial data transmission, simply put, … Read more
RS232 and RS485 are common interfaces in low-voltage applications, but some people always struggle to distinguish their differences. Below is an analysis of the RS232 and RS485 interfaces.Due to the early emergence of the RS232 interface standard, it inevitably has some shortcomings, mainly including the following four points:(1) The signal voltage levels of the interface … Read more
Consider a DC power supply with an output socket interface that has three pins: positive, negative, and ground. Accordingly, the load’s plug should also have three pins corresponding to the power supply side to correctly obtain power supply. Note that there are three essential conditions that must be met: The first is that the shape, … Read more
1. RS-232 is a serial communication interface standard, originally established by the Electronic Industries Association (EIA) in the 1960s, aimed at providing a standardized communication interface for computers and their peripheral devices. With the continuous development of computer technology, the RS-232 interface has been widely used and has become one of the most common communication … Read more
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
