Abstract

PURPOSE:To reduce the burden of a microcomputer considerably, by transmitting a synchronizing signal to the highway of a time division converter before transmitting a data signal and by not accessing a data processing device until receiving of data of one section is terminated. CONSTITUTION:When having data to be transmitted to a highway 10, a microcomputer 1 controls an interface adapter 2 to set 8-bit data. The adapter 2 generates a bit string where a synchronizing signal and a parity bit are added to this data. This pluse train is transmitted to the highway 10 through a multiplexer 3 for every time slot indicated by a control circuit 5. Meanwhile, a demultiplexer 4 extracts the pulse train on a highway 11 for every time slot designated by the control circuit 5; and after the synchronizing signal is detected by inversion of the normal state in the adapter 2, the parity check and the read of the data signal are performed.
