发动机数据接口部件（EDIU）为波音777飞机上电子发动机控制和所有其它航空电子系统之间的数字通信提供连接和翻译。每个EDIU是一个有三个微处理器和六个通道的数据系统。为了两个方向的其余飞机，该系统把ARINC429信息从EEC转换成ARINC629信息。除其数据翻译功能外，EDIU也计
The Engine Data Interface Unit (EDIU) provides connectivity and translation for digital communications between electronic engine controls on the Boeing 777 and all other avionics systems. Each EDIU is a data system with three microprocessors and six channels. For the remaining aircraft in both directions, the system converts ARINC429 information from EEC to ARINC629 information. In addition to its data translation functions, EDIU also count
