Common Communication Protocols in Power Systems: RS-232 as a Country Road, RS-485 as a Highway? A Systematic Discussion of Their Differences!

In the previous article, we discussed the differences between Modbus and RS-485, which belong to different layers. If we use a language analogy, then Modbus determines which “language” to use, while RS-485 and RS-232 determine the method of communication, such as face-to-face or telephone communication. In this article, we will discuss the differences between RS-485 … Read more

A Detailed Explanation of the Differences Between Serial Ports, COM Ports, TTL, RS-232, and RS-485

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, RX, and TX are connected. The Vcc or +3.3V power line is not connected to avoid conflicts with the power supply of the target device. 3、The … Read more
