CR7是高精密的设备,主要用于多参数研究和工业应用中。每一个CR7都单独地设置,以符合客户指定的测量要求。
CR7X控制模块是整个测量系统的基础,再加入输入/输出模块、数据采集器机箱和I/O卡。由于不同的研究之间的测量要求会有变化,CR7可以适用这些变化,更改I/O卡的设置。
CR700X控制模块是CR7大型模块化数据采集器的主要组件。订购时含内部PROMs(固件)和温度测试。CR700X包含系统的CPU、ROM、RAM、与数据存储/收集外设进行通讯的串行接口、最多可接4个I/O模块的连接接口(通常一个模块紧挨着CR700X一侧,另外三个模块距离CR700X一定距离)、还有一个键盘显示器。请参阅设置标签查看软件兼容性。
CR700X还可容纳:

A practical maximum is to connect one multiplexer per every two control terminals on the data logger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.
