In-Depth Comparison of RS232, RS422, and RS485 Serial Communication: Theory vs. Reality – A Practical Guide for Engineers
“RS485 can reach up to 1200 meters?” — That’s the textbook answer. But in factory workshops, underground cable ducts, or environments with strong electromagnetic interference, even 200 meters might not work. Why? Because theory is ideal, but real-world environments are complex. This article not only provides a detailed comparison of the technical differences between RS232, […]
