RS–485, or EIA–485, is a serial bus communication standard that overcomes the limitations of RS-232C and supports a communication speed of 10 Mbps and a long-distance communication of 1.2┬ákm owing to differential signals (balanced transmission method). It also supports N:M connections, which facilitate the connection and usage called multi-drop. The physical layer of CC-Link is a communication protocol compliant with RS-485.
