Abstract

본 발명은 RS-232C 통신방식 변환장치에 관한 기술로, 진공게이지로부터 판독한 직렬데이타를 병렬데이타로 변환하여 메모리에 저장하고, 주 CPU로 부터 데이터 요구가 있을 경우 메모리에 저장된 데이타가 주 CPU에 전송되도록 한 기술이다.The present invention relates to an RS-232C communication type converter, which converts serial data read from a vacuum gauge into parallel data and stores it in a memory, and when the data is requested from the main CPU, the data stored in the memory is transferred to the main CPU. It is a technology that allows transmission.
