	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//). Every Cresnet device on a Cresnet bus must be assigned a unique, one-byte hexadecimal Cresnet address. The range of available addresses is determined by the bus host:
