METHOD FOR CONNECTING DATA PROCESSOR

摘要

PURPOSE:To check the mounting condition of each peripheral circuit without especially determining an address number by successively transmitting a command signal to respective lines of a bus and transmitting a response signal when the command signal is received through contact pieces of a specific order. CONSTITUTION:When an ID request signal is successively transmitted to contact pieces X<1>-X<7> of a connector 42 from a control part, it is successively given to peripheral circuits mounted on connectors 425-421 through contact pieces Y8 of connectors 425-421. If the peripheral circuit which receives the ID request signal transmits an ID code peculiar to the peripheral circuit itself through contact pieces Y8 of connectors, the control part receives this ID code to confirm that the peripheral circuit is mounted, and the control part designates the peripheral circuit by similar procedures.
