Matlab 数据采集，PCI 卡被错误地检测为 PXI 机箱卡

Question

在 Matlab 2014b,2014a,2013b,2013a 中（不使用 simulink）

Windows7 64位基于会话的数据采集工具箱

使用 NI-DAQmx 14.1 和 NI-DAQmx 14.0

我的 PCI 卡被错误地检测为存在于 PXI 机箱中。这会导致以下操作失败，因为它们错误地引用了不存在的 PXI 机箱卡，而不是我实际安装的 PCI 卡。

obj.startBackground(), obj.startForeground(), 两者都会产生错误。例如：

> close all force; daq.reset;
> devID = 'Dev1';
> niIn = daq.createSession('ni');
> niIn.IsContinuous = true;
> aI = niIn.addAnalogInputChannel(devID,[0],'Voltage');
> dI = niIn.addDigitalChannel(devID,{'Port0/Line0'},'InputOnly');
> niIn.startBackground();
> NI Error -89120:
> Source terminal to be routed could not be found on the device.

Looking at the output of daq.getDevices points to a problem with the incorrect recognition:

此模块位于 PXI 机箱 4294967295 的插槽 4294967295 中。

有人可以提出解决方案吗？ Here is the output of daqsupport 也是它生成的文本文件（尽管上面的信息大多是多余的）。

请注意，全新安装 64 位 windows7 会发生这种情况。

Answer 1

将我的驱动程序回滚到 NI-DAQmx 9.8 可以解决所有测试过的 Matlab 版本 (2013a-2014b) 的问题。
