我该如何连接PCI-5640R和PXIe-5641R的AUX IO口?



硬件: Modular Instruments>>RF Measurement Devices>>PCI-5640R, Modular Instruments>>RF Measurement Devices>>PXIe-5641R

问题: 我有一块PCI-5640R或者是PXIe-5641R板卡,我希望能够访问其中的数字IO口通过AUX IO连接器。我该用什么线缆以什么方式来连接?

解答:

PCI-5640R和PXIe-5641R的AUX IO口使用的是9针的DIN连接器,美国国家仪器没有提供支持连接PCI-5640R和PXIe-5641R上AUX IO口的连接线缆。你可以购买一根Aux100 cable (part number 189919-0R5),这根线缆是设计给数字化仪使用的,含有两根PFI线。这样你可以访问到DIO_04和DIO_07这两根数字IO口。端口的针脚图可以参考NI High-Speed Digitizers Getting Started Guide,或者参考图1.

如果你需要访问两根线之外的更多引脚,你需要自制一个9针的DIN连接头。这个DIN连接头的连接器可以参考NI IF Transceivers Getting Started Guide,或者见下图2.
