Sorry its a PCI-6110!

Hi Adam

As I understand it you have a VI running on one machine acquiring data under MAX 3.0.1 and you are trying to acquire on another machine using the same vi under MAX 4.2.1.

Just a couple of questions.

1) What version of NI-DAQmx are you using on each system? You can find this out by going to MAX then expand the tree to display the Software versions. It may be that your hardware is not supported in the version of NI-DAQmx on the system with MAX 4.2.1

2) What acquisition hardware are you using?

3) Can you take a measurement on each system using the test panel?

4) If you are using NI-DAQmx tasks are they setup identically on each system?

5) Does your vi return an error?

6) You mentioned if it matters which breakout device you are using, what ones are you using? Also have you tried plugging the breakout device from the working system into the one that doesn't work?

1) I'm using NI-DAQ legacy, the Trad DAQ due to the antiquated sub-VI's in the VI of interest.

2) I'm using a PCI-6011 to log from a BNC 2090.

3) The Test Panels read perfectly... maybe even TOO perfectly.

4) What's a DAQmx task?

5) No error; but no viable data either.

6) I haven't tried plugging in the breakout device into the other PCI card only because I don't think the pins line up.

7) Thank you!

Hey all,

I'm still kinda new at LV and trying to get a VI to work that I think I understand.

I've got this VI that reads the analog inputs from a device which is seen by NI DAQ MAX 3.0.1.

I want to use the same VI to read the analog inputs from a device which is seen by NI DAQ MAX 4.2.1.

However instead of reading the voltages (which the test panels see!) I get nothing. I think the device number is correct (although I'm not sure what the number in the parenthesis means, I assume its the default channel?)

It seems like it should be so simple... but I can't get it to work. Does it matter which breakout devices I'm using??

Thanks all,

I look forward to having tougher questions in the future as my understanding grows,

Adam

Hey all,

Minor problem. Our ancient hard-drive crashed and lost the VI we use to operate a TI bnc box. Not a big deal because we have an old version of the VI saved which I can update to work properly.

My problem is some of the subVI's, which I think are standard?, can't be located by the program.

Things like AI Channel Output.vi and the such.

Is there an updated set of VIs I can use? Does that sound like a custom subVI?

Thanks a lot guys,

Adam
