RS-485 is effective in applications with significant electrical interference (noise) requiring a long transmission distance. Thus, the standard is often used in industrial applications. It is as an inexpensive local area network (LAN) connection that allows multiple receivers to connect within a multidrop configuration.
RS-485 uses a two-wire twisted pair bus with data transmission rates range from 35 Mbps (up to 10 meters)-100 Kbps (up to 1.219 meters).
