Abstract

본 발명은 로컬유닛 상호간에 데이터를 송수신하기 위한 네트워크시스템에 관한 것이다. 본 발명은 유닛들에 원칩마이콤을 내장하여 데이터처리 동작을 관장하게 하므로써 유닛 상호간에 높은 전송속도로 데이터를 송수신 할 수 있으며, 유닛의 연결이 간편하여 시스템확장이 용이한 장점이 있다.The present invention relates to a network system for transmitting and receiving data between local units. The present invention has a merit that a unit can be connected to a single chip microcomputer to control data processing operations so that data can be transmitted / received at a high transmission rate between units, and the system can be easily expanded due to simple connection.
