How do I get the features of my board?

[m610]

I'd like to be able to determine, in software, how many analog I/O and digital I/O channels my board has, along with information about the counter/timer and other features.  Also, if possible, the interrupts and DMA channels, and the DAQ library version.  I'm using a PCI-6220 board now but my software will also use a PCI-6229 board and possibly others.  I need for it to adapt accordingly and I'd rather get this information from teh board itself than from a spec sheet.  I was able to do this with another NI product, a USB-based I/O device, I forget teh model number.

Thanks.

I forget to mention that I am using the DAQmxGetDevProductType and AQmxGetDevSerialNum functions.  I'm hoping that there are other functions that can tell me more about the board in my system.

Hi m610,

The full list of DAQmx device properties can be found in the DAQmx C Reference Help (Start»All Programs»National Instruments»NI-DAQ) under NI-DAQmx C Functions»NI-DAQmx C Properties»List of Device Properties.

I hope this helps,

Thanks for the reply.

Unfortunately I couldn't find anything in the funtions section of that help file.  I forget where I ran across the ...GetName and ...GetSeriaNr functionsbut it wasn't in this section.  I just found the...MajorVersion and ...MinorVersion functions by digging through the properties listing.

It looks like there are many more fundtions than what the help files cover.  Of course, I am using version 7.4, the version that came with my 6220 board, so that may have changed in more recent versions.

Hi m610,

Many of the device capability properties were added in DAQmx 8.3. You'll need to upgrade to a newer version of DAQmx to use DAQmxGetDevAIPhysicalChans() and such.
