Serial devices are used around the world as integral components of industrial automation systems. This is due in part to the fact that RS-232/422/485 interfaces are easy to set up and economical to use. For example, the 2-wire RS-485 interface can be used to connect as many as 32 serial devices to a single half-duplex line. Since the transmission distance can be up to 1200 meters, RS-485 is suitable for many factory applications. If more devices or greater distances are required, RS-485 repeaters can be used to extend the 1200 meter limit or increase the number of devices connected to the system.
