5 5  Communications between Crestron Cresnet devices occurs on the Cresnet bus. Cresnet is Crestron's proprietary 4-wire communications network that provides both 24V DC power and low-voltage, bidirectional communication that adheres to to RS-485 standards.

7 -Each job with Cresnet devices will have at least one Cresnet bus network. Every Cresnet bus network has a single //host// or //primary// device and one or more //client// or //secondary// devices (older materials may refer to hosts as //masters// and clients as //slaves//). There are two limiting factors as to the number of Cresnet devices that can be supported on a single Cresnet bus: the number of available Cresnet addresses and the amount of available power.
