Point: 1. The serial port and COM port refer to physical interface types (hardware). TTL, RS-232, and RS-485 refer to signal level standards (electrical signals). 2. When connecting devices, generally only GND, RX, and TX are connected. The Vcc or +3.3V power line is usually not connected to avoid conflicts with the power supply of … 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
Source: ContentCompiled by Semiconductor Industry Observation (ID: icbank) from allaboutcircuits, thank you. Although both standards have long been used for serial communication, RS-485 offers valuable features that RS-232 lacks. Learn more in this article. Any form of communication requires rules to help ensure that everyone stays consistent. In electronics, these rules take the form of … 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
