cRIOでNI 9219を熱電対と使う場合のCJCチャンネル（FPGA I/Oノード）の作り方 ｃRIOでNI 9219を熱電対と使おうと考えています。プロジェクトの中のFPGAターゲットでCモジュールの追加でNI 9219を追加しました。FPGA I/OノードとしてCJCチャンネルを作ろうとしましたが、リストに表示されません。 どのようにしたら、CJCチャンネルをFPGA URL: http://digital.ni.com/public.nsf/allkb/D99A5902053E0DAE8625731500129D78

NI-9219をCompact DAQで使用する場合のサンプリングレートに関して Compact DAQでNI-9219により測定を行うと、設定したサンプリングレートでデータは読み取れるのですが、同じデータが繰り返し集録されてしまいます。データの更新頻度を上げるには、どのようにすいればよいでしょうか URL: http://digital.ni.com/public.nsf/allkb/3ED773B7C63AB85886257314000C348A

Incorrect Initial Sample with NI 9211, NI 9217, or NI 9219 in NI CompactDAQ When I perform a hardware-timed acquisition with an NI 9211, NI 9217, or NI 9219 in NI CompactDAQ, the first sample that I read is old/stale. The rest of the data I acquire looks fine, but the first sample is not what I expect. URL: http://digital.ni.com/public.nsf/allkb/EC6B7C1528D610CC862572C70063366D

Troubleshooting Digital Output and Pulse Generation on the NI 9472/9474 I can't seem to drive the digital outputs low on my NI 9472/9474. I also can't seem to generate a correct TTL pulse train on my NI 9472/9474, what could be the problem? URL: http://digital.ni.com/public.nsf/allkb/C9019BC9F6544005862572BF0059B532

Incorrect Voltage Readings on the NI 9237 I am attempting to read a known voltage with my NI 9237 using a test panel in MAX, and the voltage reading is incorrect. I have verified that the voltage is 10 mV with a DMM or other measurement hardware; however, it seems the NI 9237 is reading 4 mV. Why I am getting this reading?
