Abstract

PURPOSE: To reduce the number of signal lines by dividing word-unit data on a byte unit and by transferring data via a P-S converter circuit and S-P converter circuit on a byte- unit start-stop synchronization system.
CONSTITUTION: Word-unit write data from computer A are stored on a byte unit in registers 2 and 3 of interface circuit B, converted by P-S converter circuit 6 into byte-unit start-stop synchronous series data, and transferred to input-output terminal equipment C together with address signals from address register 1. In the same way, read-out data from input-output terminal equipment C are also divided on a byte unit by register 44, converted by P-S converter circuit 45 into series data, and then fetched to computer A via interface circuit B.
