Finding Serialnumbers of non-DAQ cards

[Paul_Knight_Lockheed_Mart]

I have a requirement to track all serial numbers of instruments used in a test. I am able to use DAQmxGetDeviceAttributes for my DAQ type devices, PXI-4071, 5412, 2567, 2569, 6535, and 6722.  But I have PXI-8432/2, PXI-8433/2, and a PXI-8513/2 that do not use the DAQmx.

How do I get access to the serialnumber?  MAX can do it, so I should be able to.

I am using LabWindows/CVI.

Hi Paul, 

I think the ModInst library might get you there.

Jesse,

Thanks, this is what I wanted.

Jesse,

Attached is a screenshot of what I get running the example program for NI-ModInst.  The help states using the empty string will get all instruments in the system.  The first list is using "NI-DMM" and the second list is using "" in

OpenInstalledDevicesSession( "", &vi, &deviceCount);

I have 11 instruments in my PXI system.

Slot Instrument

  3   4071

  4   5413

  6   2567

  7   2569

  9   6535

10   6535

12   6722

14   8234

15   8513/2

16   8433/2

17   8433/2

Does it make a difference if the instruments are a mix of PXIe and PXI?

Hi Paul, 

It seems like it is only looking for a DMM or some other class of driver. You can try cycling though all the classes and make sure you can see your devices. It seems like something in the program, but I can look into it further if you still are having problems.

Jesse,

It appears that this library does nothing.

I have tried 

iLocalFail = niModInst_OpenInstalledDevicesSession("NI-SWITCH", &uiDeviceHandle, &iDeviceCount);

iLocalFail = niModInst_OpenInstalledDevicesSession("NI-HSDIO", &uiDeviceHandle, &iDeviceCount); 

Both of which should have return with 2 devices, however both returned with 0 and no error.

I know MAX does everything I want to do.  It finds every serial number and board type except for the PXIe-8133 and PXI-8234.  MAX doesn't organize the data very well, but at least it finds most of it.  Can you find out how MAX does it?

I would be happy to. Let me set up a PXI and see what I find.
