[Column] What is Serial Communication? Types of Network Configurations and Physical Layer Standards
What is serial communication? Introducing the types and characteristics of network configurations, as well as the standards of the physical layer! / Leave application development to Nippo! /
In recent years, the adoption of serial communication has been increasing due to advantages such as space-saving, cost reduction, and high performance. Serial communication uses one or two signal lines to send data sequentially, transmitting one bit per clock cycle. Although there were concerns regarding speed, high-speed serial communications like USB and PCIe have since become widespread. Serial communication can be broadly classified into two types: asynchronous and synchronous. Asynchronous types include I2C, JTAG, and UART, while synchronous types include USB and PCIe (high-speed serial communication). High-speed serial communication features clock, data, and recovery functions, excelling in terms of speed. <Serial Communication Physical Layer Standards> 1. RS232-C 2. RS422-A 3. RS485 4. Ethernet In industrial equipment, RS485 is the most commonly used. This standard allows multiple devices to be connected on the same data line, ensuring real-time control, making it suitable for industrial applications.
