We often discuss RS-485 in terms of its technical specifications: differential signaling, 120Ω termination resistors, and multi-drop topology. But to truly appreciate its enduring dominance, we must shift our perspective.

In modern industrial and network communications, RJ45, RS485, and RS232 are three critical interface standards. Despite sharing "RS" or "RJ" in their names, their application scenarios, technical features, and protocol specifications differ significantly. T

​In the realm of industrial communication, RS485 and Ethernet are two prominent protocols that serve distinct purposes. While both are widely used for data transmission, they have unique characteristics, advantages, and applications. This article aims to provide a detailed comparison of RS485 and Ethernet, helping readers understand their differences, strengths, and suitable use cases.

RS-485 is a commonly used serial communication standard, mainly used for long-distance and multi-point communication. It can support multiple devices to communicate in the same network and is usually used in industrial automation and control systems. The advantages of RS-485 include strong anti-interference ability, long transmission distance (up to 1200 meters) and the ability to connect multiple devices (up to 32 drivers and receivers).

In the fields of industrial automation, communications, and data transmission in various electronic devices, serial communication standards are crucial. The RS232 bus standard and the RS485 bus standard are two common and widely used serial communication standards. This article will explain in detail the significant differences in performance and application scenarios between the RS232 and RS485 bus standards.

Hubs play a vital role in modern industrial automation and smart home systems. They are used to connect and manage multiple devices to ensure efficient and reliable data communication. This article will explore two common hubs - Zigbee hub and RS485 hub, and analyze their characteristics, applications, advantages and disadvantages.

RS-232,RS422,RS485 and CAN bus are common communication methods in IoT applications and can be used for data transmission and communication between different devices. Different communication lines have different transmission rates and transmission distances. How can we enable them to achieve longer-distance transmission?

RS485 communication, as a commonly used serial communication standard

RS485 is a serial communication standard that defines a way to communicate data between multiple points. This standard belongs to the EIA/TIA-485 standard and is jointly issued by the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA). RS485 is commonly used in industrial control systems, automation equipment, instrumentation, building automation, and other applications that require long-distance, multi-point connections, and high immunity to interference.
