CCN BUS ARCHITECTURE
• An address is required of all devices on the bus.• No two devices on the same CCN system may ever have the
same address.• A CCN and CCS address consists of a 3 digit bus number
and a 3 digit device number.
The Key to the CCN BUS is Addressing:

CCN BUS ARCHITECTURE
• Legal bus numbers are 0 to 239 inclusive– The primary bus number is always “0”– Secondary bus numbers are 1 to 239 inclusive.
• Legal device numbers are 1 to 239 inclusive.
• A repeater module and NAM configured to work with a computer are not addressed.
CCN BUS is Addressing:Example Address: ( 024 , 127)

• For a simple and multiple TEMP system, the only addressing rule is to never duplicate addresses.
• For a simple TEMP and multiple TEMP system, bus communication is at a minimum, and therefore usually a single bus is sufficient.

• For a simple and multiple VVT system, the only addressing rule is to never duplicate addresses.
• The bypass controller MUST be addresses one less than the monitor stat.• Zone controllers must be addressed below the bypass controller.
