Abstract

본 발명은 RS-232C 전송장치와 RS-422 전송장치간에 데이타 송수신이 가능하도록 된 직렬전송신호 변환장치에 관한 것으로, 종래에는 상기 2가지 방식의 전송장치가 서로 다른 형태로 구성된 데이타를 사용하고 있으므로 RS-232C 전송장치가 설치되어 있는 시스템과 RS-422 전송장치가 설치되어 있는 시스템과는 서로 데이타를 주고 받을 수 없는 문제점이 있었다.The present invention relates to a serial transmission signal converter that is capable of transmitting and receiving data between an RS-232C transmission apparatus and an RS-422 transmission apparatus. In the related art, the two types of transmission apparatuses use data configured in different forms. There was a problem in that the system with the RS-232C transmission device and the system with the RS-422 transmission device could not exchange data with each other.

본 발명은 RS-232C 방삭의 데이타는 RS-422 방식의 데이타로, RS-422 방식의 데이타를 RS-232C 방식의 데이타로 변환할 수 있는 변환장치를 구성하므로써 서로 다른 방식의 두 전송장치간에 데이타 송수신이 가능하도록 된 것임.In the present invention, RS-232C data is RS-422 data, and the data transmission between two transmission devices of different methods by configuring a conversion device capable of converting RS-422 data into RS-232C data. Sending and receiving is enabled.
