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:

21 -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.

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.
