PXI computer

[behluls]

Dear sir,

My test stand sw is working normally on Windows XP also PXI cards but when I turn off my computer (when the windows message is " you can turn off the computer safely) led on the PXI computer does not turn off so that to I can use the computer again I need the to pull out the power cable. How can I solve this led problem? Could you help me?

Best regards...

Hey behluls,

Thank you for contacting National Instruments.  What behavior do you see when you flip the power switch or press the power button on the chassis?  Also, what chassis are you using (NI-####)?

Hello Jason,

I use the NI PXI-1042Q chassis and when I flip the power switch the computer does not turn off and the led does not turn off so that I need the power off pulling out the power plug.

Thank you

Hey behluls,

I forgot to ask you this before.  Are you using an embedded controller or an external PC to control your chassis?  If you are using an embedded controller, what model number is it?

Hello Jason,

I'm sorry, forgot the configuration name. I use the PXI 8190 computer and the module cards are;

-PXI 8196 Embadded controller

-PXI 6508 Digital I/O

-PXI 8420 RS 232 serial

-PXI 5122 Digitizer

Hey behluls,

It sounds like there could be something wrong with your chassis.  I would suggest going here and creating a service request for phone support.  Once you call in we can take it from there.

Hello Jason,

I have another question. I want to use PXI 5122 digitizer card as logic analyser. I want to do these prosesses:

- I'll measure the square wave as logic "1" or "0" and I'll count the 0 and 1 number. End of this I"ll compare them the data was stored before.

Can this prosess possible and how can do this or could you show me a application / example?

Thank you

Hey behluls,

There is a great Logic Analyzer example that ships with LabVIEW.  Unfortunately it is with our NI-HSDIO driver that is only supported by 654x, 655x, and 656x cards.  The NI-SCOPE software isn't really used as a Logic Analyzer so I am not sure if there are any specific examples available for that.  I would still check in LabVIEW's Example Finder to see if anything looks like a good start.
