Serial communication is the most basic communication method that electrical engineers face, with RS-232 being the simplest of them. Many beginners often get confused about the relationship and differences between UART and RS-232, RS-422, and RS-485. This article will discuss the understanding of these concepts to help clarify their relationships. If we compare serial communication … Read more
Abstract: This article introduces three common serial data standards: RS-232, RS-422, and RS-485, according to their technical specifications and electrical interfaces. It discusses cable termination techniques, the use of multiple loads, RS-232 daisy chain connections, conversion from RS-232 to RS-485, conversion from RS-485 to RS-232, and powering RS-485 conversion from RS-232 ports. Introduction “The wonderful … Read more

What are the differences between serial ports, COM ports, TTL, RS-232, and RS-485? We often encounter these in our projects, so let’s summarize them. 1. Serial ports and COM ports refer to the physical interface form (hardware). TTL, RS-232, and RS-485 refer to the level standards (electrical signals). 2. When connecting devices, generally only GND, … Read more
RS-232, RS-422, and RS-485 are all serial data interface standards. RS-232 is the most widely used serial interface for PC communication. RS-232 is defined as a single-ended standard that increases communication distance in low-speed serial communication. RS-232 uses an unbalanced transmission method, known as single-ended communication, while the RJ45 interface is typically used for data … Read more
RS-232 RS-232-C is a serial physical interface standard established by the Electronic Industry Association (EIA) in the United States. RS is the abbreviation for “Recommended Standard”, 232 is the identifier number, and C indicates the number of revisions. Its full name is “Serial Binary Data Exchange Interface Technology Standard between Data Terminal Equipment (DTE) and … Read more
**Introduction** In many industrial and automotive applications, protecting interface transceivers from various electrical overstress events is a major concern. Transient Voltage Suppressor (TVS) diodes are commonly used for this purpose as they clamp voltage spikes by creating a low impedance current path. The electrical characteristics of TVS diodes are determined by several process factors. These … Read more
