国产与进口激光照排机数据流差异及其兼容化方法研究

Study of the Compatibility of JZJ—400 and ECRM Laser Typesetters on Data Flow

分析了国产激光照排机与进口机器在数据格式上的差别，并通过全硬件电路，实现了从国外照排机的并行格式向国内机器的串行数据格式的转换。在同一套出版系统的支持下，做到了国产ＪＺＪ—４００型激光照排机与进口ＥＣＲＭ１５４５Ｓ／ＶＲ４５两种机器接口信息的完全兼容。

A method of computer data conversion in laser phototypesetters is presented.Through the circuit proposed,the parallel data used in foreign standard machines are converted into serial ones, which are available for use in chinese standard machines.Thus,the two kinds of standard machines get compatible.
