What is RS-422 used for?

RS-422 is a serial communication protocol widely used in various industrial and commercial applications due to its long-distance transmission capability, high data transfer rate, and resistance to noise interference. It is suitable for connecting multiple devices in a network, especially in environments where reliable data transmission over extended distances is required, such as factory automation, telecommunications, data acquisition systems, security and monitoring systems, and point-of-sale (POS) systems.
