为什么我的USB数据采集模块出现“Unable to Loacate a Driver”错误？ 我刚刚购买了一个USB数据采集模块（9211或9215），并在Windows系统的计算机上安装了NI-DAQmx。当我插入我的USB模块时，我得到一个错误：“Windows was unable to locate a driver for this device.”该如何出来？ URL: http://digital.ni.com/public.nsf/allkb/01F862902AA81CE6482573A200098B96

How Do I Connect a Quadrature Encoder to NI ELVIS When Using an M Series Device? I am trying to use two angular quadrature encoders on an NI ELVIS with an M Series device using DAQmx in LabVIEW. The B terminals for the counters are inaccessible because they are set at RESERVED (ctr0) and SCANCLK (ctr1). These lines must be reassigned.

Creating a Delayed, Retriggerable and Finite Pulse Generator I want to perform a delayed, retriggerable, finite pulse train generation. When I generate a single finite pulse from a retriggerable counter (Fig. 1 - Delayed retriggerable single pulse), it behaves differently than generating a finite pulse train from a retriggerable counter (Fig. 2 - Delayed URL: http://digital.ni.com/public.nsf/allkb/204538A044431C9B86257377004EB952

DAQmxでアナログトリガソースとしてチャンネルを設定できないのはどうしてなのでしょうか。 アナログトリガをアナログ入力チャンネルに設定するとエラー-200265が起きてしまいます。 URL: http://digital.ni.com/public.nsf/allkb/CFCA8CE94D9E06A686257384000F620A

Why Does My Specified Channel Not Work as an Analog Trigger Source in DAQmx? I have configured my analog trigger to trigger off of one of my device's analog input channels, but I receive DAQmx error -200265. URL: http://digital.ni.com/public.nsf/allkb/BEBB10D02D72798A8625736B0076B09A

Why Does My Real-Time Controller with NI-RIO and NI-Sync Crash? I have a real-time controller with NI-RIO 2.3 and NI-Sync 2.0.1 installed and the controller will not boot. Why does my controller crash when booting? URL: http://digital.ni.com/public.nsf/allkb/FECB7E15D5025002862573630012F384

Unexpected Delay When Using DAQmx Analog Start Trigger When I use a DAQmx analog edge start trigger with an M Series DAQ device, my program appears to last 250-300ms longer than when I do not use an analog edge start trigger. Why is this happening, and is there anything that I can do to get around it? URL: http://digital.ni.com/public.nsf/allkb/AF8AA09A3323B0B38625734F00496E02

使用DAQmx模拟触发的意外延迟 当我使用M系列DAQ设备的模拟边沿开始触发(DAQmx驱动)时，程序运行比不使用触发要长250-300毫秒。为什么会有这样的现象，是否有什么方法可以解决这个问题？ URL: http://digital.ni.com/public.nsf/allkb/5A341AF57090C4E6862574A0003F2D5A

Internally Routing Counter Signals in LabVIEW I want to route the output signal of one counter to the source/gate of another counter on the same card or to a specific PFI line. Can I do this without externally connecting the two pins? URL: http://digital.ni.com/public.nsf/allkb/8A85E97855EDADC98625730C00065F58
