How is RS485 better than the RS422 protocol?
RS485 is a more versatile and advantageous protocol than RS422 in several ways. RS485 supports multi-point communication, connecting multiple devices on the same bus, while RS422 has uses in point-to-point configurations. RS485 provides better noise immunity and has a longer communication distance capability. Industrial and building automation systems support RS485 with higher baud rates and wider adoption.
