is there a way to override this? such that i get a "original" microphone input?

Re: Communicate with USB cDAQ-9174 and PXIe-8840 RT Controller
Hello,
If you are connecting the 9174 cDAQ chassis to a PXIe-8840 running PharLap on it, in order to detect the cDAQ chassis in NI MAX you will need DAQmx driver version 18.0 or lower.
However, if the PXIe-8840 controller has Linux RT running on it, you should ideally be able to detect the chassis in NI MAX with latest versions of DAQmx driver (19.0 or higher) too.

Re: Data logging failure...
Dear, Emboar.
Thank you very much for your opinion.
I changed the file storage location to'/home/lvuser/test.tdms' by referring to the link you provided, but the same thing happens.
Maybe it's because of another problem.
Thank you.

Hi Kwon,

How does it stop "completely"? Due to (inefficient) error handling? Due to BSOD?
Mind to attach your VI? How did you implement the serial communication with ADAM?

Even with your LV2019 installation you should be able to provide a downconverted set of VIs using "Save for previous"…

Error 7 was removed? Or still there?

Re: Data logging failure...
Error 7 is gone, but the data is still only measured as zero...
Thank you.

When I checked the converter of MOXA, I confirmed that using ADAM 4572, MODBUS TCP communication is possible without using virtual comfort.
Thank you.

Re: Data logging failure...
On FPGA VI, there is type mismath. Mod2/AI0 is "signed, 24,7" but FPGA FIFO is "signed, 26,5".
Why don't you fix it.
When you directly see the returned FXP value on RT VI, do you also see "ZERO"?

Re: NI MAX does not recognize my device connected via USB
Hey dear community,
sorry for my delayed response. I figured out a lot the last day and also talked to Thorlabs.
I dont know why, but my stage isnt working with APT via Labview. Somehow the motor wents crazy and doesnt do any step, but still you get horrible noises. So anyway I tried with the alternative Kinesis, which uses .net methods in Labview. I tried out an example of Thorlabs and worked out pretty well. But here is my next problem, Thorlabs doesnt have any description for the different methods. They suggest you the help file from the download folder, but this isnt helpful. There are only descriptions for other programming languages. I also talked with Thorlabs about this, but they dont have anything else, but suggested me other example files of them. But still I dont know how I should build up a VI with methods, where I dont have any descriptions. Its really annoying, because you never know, if you are doing the correct step. Did anyone else had such a problem?
Lovely regards

Save data in Labview NXG
hello,
I am doing experiment using USRP and Labview NXG. Now I can get data but I need to save them to a .txt file. I tried some methods but the problem is the system only save the data in last moment. All the previous data is covered.
So, is there any way to save all the data in the whole experiment? It is better to save the timestamp together.
thanks

Re: Labview capture audio
I'm not sure if this can be fixed from LabVIEW (easily).

Re: MAX Configuration Server Corrupt
Just to re-clarify my question. I am after the best way of making code resilient to MAX database corruption issues. A lot of our code goes to customers who aren't knowledgeable with NI software/hardware and as far as they are concerned just want a magic black box. Everyones comments has confirmed that I am thinking along the right lines so I am going to have an experiment today.
wrote: We have ~20 computers using DAQ devices, and I get one with a MAX database corruption every 3-6 months. It's definitely not due to software installation/update, either. There is a reason NI put a menu item in MAX to fix it...
Mancho, I am guessing you are referring to the 'Reset Configuration Database' button?
wrote: @BS, look into my older posts about NI Device Manager. It is possible to automatically detect a new device and then associate it with everything DAQmx-ish with a simple executable and some adroit HKEY NInja like moves in the same installer. <Don't do this at home! We are professionals >
What posts are you refering to here JpB? I can't find them on your profile.

Append Data to excel worksheet
Hello,
I would like to append data in Excel to an already existing worksheet if it exist. I would like to add this new block of data 1 column to the right of the last column of data, i.e., check for the last column in the existing worksheet for data, skip a column, then add the new data. I would like to add to the already existing worksheet after each run if the excel sheet exist.
I have attached what I have done far. I am unsure of how to check for the last column with valid data then to append the new block of data.
Thanks for your help.

Easy way to compare sw versions between PC's
Hi
Is there a easy way to compare sw versions between PC's
I can see versions in MAX, but it is cumbersome to compare between a lot of PC's manually.

LabVIEW Vision Development Module を使わずに物体の重心を求める方法
現在私は、LabVIEWとGigEカメラを接続して、カメラから取得した画像を用いて背景差分をするプログラムを作成しています。
そこで、背景差分して表示した物体の重心を表示するプログラムを作ろうと考えています。
粒子解析や配列から物体の位置を表示しようとしていますが、なかなかうまくいきません。
何かアドバイスを頂戴したいです。
よろしくお願いいたします。

Figure2 might be helpful for you. Do you really need txt?
I recommend to work with TDMS because RF data would be large in most case.
