After NIDAQ850 installation usb-6009 causing problem

[Chemist_and_Crystallographer]

I was using Using DAQmx 8.1.of1 without problem but needed higher versions for cahannel listing on various Ni daqs. Then installed NIDAQ850.
After NIDAQ850 installation can not start task on usb-6009. And get "The software has entered an unknown state - usually as a result of a cascade failure induced by an unexpected series of state inputs." error message. MAX is working fine.

PCI-6281 is working fine.


WinXP, delphi.

Hello Omer,

Thank you for posting on the National Instruments Discussion Forums.

Would you happen to have the exact error code with this error?  This error might occur if you have multiple VIs that are trying to access the same board.  This might also occur if you have code in seperate parts of your program that might be trying to access the board at the same time. 

Can you measure the signal in Measurement and Automation Explorer?  Can you do a self-test under DAQmx Devices?  Try resetting the device in Measurement and Automation Explorer.  Also, are you using a DAQmx Clear Task anywhere in your code?  Once again, it will help if you could provide a little more information on the error.

I can not test it anymore because winxp dead now. I tried to uninstall NIDAQ850 but could not complate the uninstallation. Then tried to install NIDAQ830 but failed. Then tried to remove NI enteries in registry manually 😞 . Winxp dead.

The program was  working with DAQmx 8.1.  and still working with DAQmx 8.1 on other computers. I have two 6009, one PCI-6013, one PCI-6281 and going to have more M series USB. The all work with   DAQmx 8.1. But only USB-6009 causes problem with DAQmx 8.5.

I can measure the signal in Measurement and Automation Explorer.

Is there difference beetween DAQmx 8.1 and DAQmx 8.5 in terms of accessing the board at the same time?

I can not give more detailed information but try DAQmx 8.3 first.

Perhaps it is windows problem!

Hi Omer,

It seems like the same code you have is working on DAQmx 8.1 on different computers and not working when you use DAQmx 8.5 on this computer.

When you say :

             They all work with   DAQmx 8.1. But only USB-6009 causes problem with DAQmx 8.5.

Are you using the same code on all of these different boards?  Do you have multiple tasks in that code, which might be accessing the same channel?  If you have already tried using DAQmx 8.3, please let us know the results of that as well. The best way to remove programs on your machine is to use the "Add Remove Programs" in the control panel > Click "change" under National Instruments Software > Find your DAQmx driver > Remove the driver.

It would really help if you posted the code and maybe even a screen shot of the error that you are receiving.

Have a great day.

Regards,

Hi  Raajit,

            Are you using the same code on all of these different boards?
 Yes
            Do you have multiple tasks in that code, which might be accessing the same channel?
As far as I know, No. But I will test it with basic code.

Then asks to restart. And BLUE SCREEN again :(. Even Safe Mode does not work. Then go back to linux restore winxp registry.

I have restored winxp registry with the help of my lovely trustable LINUX system. Add Remove Programs   National Instruments Software repair works fine. If I try to uninstall DAQmx8.5, I get blue screen after restart.

There could be problem with my two years old winxp system.
In order to prevent possible conflict(s) Daxmx 8.50 may creates,  Im going to do  Bill Gates solution: reformat Drive C.
And try both  DAQmx8.5 and DAQmx8.3 on new winxp system.
