RS-485 is a popular serial communication standard used in industrial control systems, automation, and other applications where long-distance communication is required. Unlike RS-232, RS-485 uses differential signaling, which makes it more robust to noise and interference, making it ideal for industrial environments. Moreover, RS-485 supports multi-device communication on the same …
