485 Communication Problems [Copy link]

I would like to ask an expert, does the common ground or non-common ground (isolation) of the two sides of 485 communication affect the communication distance? Thank you!

To be more precise, the question you asked should be about the relationship between whether the system and the bus share a common ground and the communication distance. The answer is that it has nothing to do with it. Isolation is to solve the problem of the impact of bus coupling interference signals on the system, which is obviously unrelated to the communication distance.
