Abstract
PURPOSE: To cause no inconvenience for the adjustment work even in case the adjustment is carried out with no connection to the data pack mistakenly by holding the memory with no connection to the data pack in the case of the specifications to use the data pack.
CONSTITUTION: In case the contents of option board 10 indicates existence of the date pack, CPU4 conveys the control code to data pack 12 via transmission control circuit 11 for holding for a fixed time. If some answer is given from pack 12 within that period, CPU4 gives the address conversion for the program selection to ROM6 and then stops the transmission in case no answer is given. And the designation signal is transmitted to ROM6 from CPU4 in order to select the routine for presentation of the adjustment report. Thus the contents of RAM5 is not cleared by the rewriting signal sent from CPU4 but held to display 8 HOLD via display driving circuit 7. As a result, no inconvenience is caused for the adjustment work by holding the contents of the memory even though the adjustment is carried out with no connection to the data pack 12 mistakenly.
