RS422 Insights

What is RS422?

RS-422 is a technical standard that specifies the electrical characteristics of balanced serial communication. It's used for transmitting data serially over twisted-pair cables, often over longer distances and at higher speeds than RS-232. It's commonly employed in industrial automation, computer peripherals, and telecommunications equipment.
