I am using 2011b, and daq toolbox. I would like to get the information from the DAQ I'm using such as serial number. Something like the SCPI command "idn?" provides.

I did see someone wrote a C utility, but seems like m-code should be able to do it too.

Hi Mike,

You can directly access the NIDAQmx driver functions from DAQ toolbox.

[status, serial] = daq.ni.NIDAQmx.DAQmxGetDevSerialNum('Dev3', uint32(0))

Hope this helps,

Manisha

Hi Manisha, thank you. That does give a number out, but the reported number is 23363818, where as the case and MAX say 16480EA. Hence, they list them in HEX in MAX and on the back, so dec2hex makes them the same. Awesome.

I am looking for all the related commands to what you provided. Do you have a link? Thanks

Most exellent help again.

Yep. Thanks. Just hoping for M-code only.

You probably will not be able to do this with pure m code. The MATLAB DAQ Toolbox does not expose the serial number information, so you need to call in to the NI shared libraries. Calling in to the NI shared libraries from MATLAB requires a C header file that defines the arguments of all of the calls supported by the NI shared library. (The MATLAB routine used would be loadlibrary())

On the other hand, at the moment I would not rule out the possibility that there might be an ActiveX / DCOM interface to NI's Measurement & Automation Explorer that you might be able to use to "remote control" the Explorer to get down to the serial number. (I haven't checked out this possibility.)
