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. |

| |
20.10 | 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: |

20.10 | 25 | Power considerations also play a role in determining the number of Cresnet devices which can be supported on a Cresnet bus, however we will not cover them here due to the wide array of variables which impact power calculations and determining whether there is sufficient power for a given device. |
