PCI-6115 channel not working

[Mcdullna]

I am using Labview 7.1 for PCI-6115. In the configuration, it shows up the device. But when I do the test panel, either Anolog Input or Output seems not working. What could be problem be? The Counter I/O works.

Thanks for help here!

Mcdullna,

Can you explain what you mean when you say that the Analog Input and Ouput are not working? Are you reading unexpected values? Are you getting a timeout error? Can you provide screenshots of your test panel?

Also, what version of your DAQ driver do you have?

Thanks Leah! 

Sorry that I am very new to this field, and did not quite make it clear.

I am using DAQ 7.2, and BNC-2090. In MAE, the software recognized the PCI-6115, but it seems that there is a failure in the channel configuration. There is no voltage reading when I applied certain (3V) voltage to the analog input. Here is a screenshot of the test panel.

Thanks so much!!

Hey,

So it looks like you are able to run a test panel, you just aren't reading any voltage. Is that correct? What pins do you have your source connected to?

[Mcdullna]

Yes, and I applied the voltage on ACH0 pin, and also tried ACH1 and ACH2, all failed. It worked last year, but somehow not any reading now. Any ideas? Thanks!!

Interesting, so none of the channels are working? Did you check the pinout of the device to make sure you have it wired correctly?

Another thing that you should check is that your signal source is working correctly.

Hi,

I'm also having this same problem with my 6115 but its only on AI1.  I have another old card with a bad channel that reads the same voltage but even that one shows some fluctuation; this card only shows a flat line on AI1 regardless of whats connected.  Have you found any solution to this issue?

Hi,

Which version of LabVIEW and DAQmx are you using?  Also, you might want to start a new thread for your own issue!
