RS-485: Still the Most Robust Communication
Despite the rise in popularity of wireless networks, wired serial networks continue to provide the most robust, reliable communication, especially in harsh environments. These well-engineered networks provide effective communication in industrial and building automation applications, which require immunity from noise, electrostatic discharge and voltage faults, all resulting in increased up-time. This tutorial reviews the RS-485 protocol and discusses why it is widely used in industrial applications and the common problems it solves.
