This article introduces the basic concepts of the serial communication protocols RS-232, RS-422, and RS-485, including baud rate, data bits, stop bits, parity bits, and handshaking information. 1. What is Serial Port? The concept of serial communication is quite simple. Serial ports send and receive bytes one bit at a time. Although it is slower … Read more
01 【Common Ground】 RS-232, RS-422, and RS-485 all belong to UART, which stands for Universal Asynchronous Receiver/Transmitter. They can complete the communication process using only two signal lines (Rx and Tx); However, due to the different voltage levels used by each, when converting from UART to RS-232, RS-422, or RS-485, a chip such as SP3232E … Read more
Click on the above blue text to follow us Serial communication is the most basic communication method faced by electrical engineers, and RS-232 is the simplest among them. Many beginners often struggle to understand the relationship and differences between UART, RS-232, RS-422, and RS-485. This article will discuss these concepts to help clarify their relationships. … Read more
The main differences between RS-232 and RS-485 are: 1. The transmission methods are different. RS-232 uses an unbalanced transmission method, known as single-ended communication. In contrast, RS-485 uses balanced transmission, which is a differential transmission method. 2. The transmission distances are different. RS-232 is suitable for communication between local devices, with a transmission distance generally … Read more

Serial Communication refers to a communication method for data transmission through serial ports. Data is transmitted bit by bit through data signal lines and ground lines. Common serial ports include RS-232, RS-485, and RS-422. It is important to note that serial ports are only interface standards, specifying the electrical standards of the interface, and not … Read more
