Customer Technical Training CCN BUS ARCHITECTURE The Key to the CCN BUS is Addressing: • 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. 6/28/98 CCN_BUS 13

Customer Technical Training CCN BUS ARCHITECTURE CCN BUS is Addressing: Example Address: ( 024 , 127) Bus Number Device Number • 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. 6/28/98 CCN_BUS 14
