20.3	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.
1.1	6
20.9	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//). Every Cresnset device on a given Cresnet bus must be assigned a unique, two-byte hexadecimal Cresnet address, and the amount of available addresses is determined by the bus host. In addition

	13	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.
