YS-80仪表与YEWPACK MARKⅡ系统同时使用时,在两个系统之间为了进行通信,配备了供通信总线进行转换所需要的适配器,即LCS插卡和NC50插卡。 LCS和NC50在功能上与YS-80和YEWPACK MA—RKⅡ系统间通信总线上数据类型、型式及内容相匹配,承担了由YEWPACK系统内部通信向系统外部通信转变的出口、入口的桥梁作用,所以称做YS-80的门通道单元(GATEWAY UNIT),简称SGWU。一、SGWU门通道单元 SGWU是一个以MC68B02微处理器为中
When used in conjunction with the YEWPACK MARK II system, the YS-80 instrument is equipped with adapters for communication bus conversion, ie LCS cards and NC50 cards, for communication between the two systems. The LCS and NC50 functionally match the data type, type and content on the communication bus between the YS-80 and YEWPACK MA-RK II systems and assume the role of a bridge between the entrance and exit of the transformation from the internal communication of the YEWPACK system to the external communication of the system Known as the YS-80 door channel unit (GATEWAY UNIT), referred to as SGWU. A, SGWU door channel unit SGWU is a MC68B02 microprocessor as a medium
