In applications such as CAN and RS-485, it is generally recommended to use shielded twisted pair cables for networking and wiring to reduce external interference on bus communication. Many engineers understand this recommendation but do not know the underlying reasons. This article will briefly introduce the principle of interference resistance in twisted pair cables. 1Differential … Read more
The main differences between RS-232 and RS-485 are: 1. The transmission methods are different. RS-232 uses an unbalanced transmission method, known as single-ended communication. In contrast, RS-485 uses balanced transmission, which is a differential transmission method. 2. The transmission distances are different. RS-232 is suitable for communication between local devices, with a transmission distance generally … Read more
