What Code Is Returned by the Init_DA_Brds NI-DAQ Function Call for the NI PCI-6514 Device?

[Mike Evans]

In fact, I can't find a simple table of what board returns what device code.

I've found the Init_DA_Brds function in the ni-daq manual but there's no hardware list.

Does such a list exist?

The device numbers that were available in Traditional NI-DAQ are no longer relevant nor available in NI-DAQmx. The 6514, being a board which is only supported in DAQmx, will not have a listing for a device code in the Traditional NI-DAQ function reference help.

What you do have with NI-DAQmx are System Property Nodes and Device Property Nodes. The System Property Node can give you the devices installed on the system. The Device Property Node allows you to retrieve the Device Serial Number.

In short, there is no current device code similar to that in Traditional available in DAQmx. You will have to go about a different means of determine the device number using DAQmx.

Thanks Jon.

Unfortunately we can't use DAQmx as we have LabWindows 6.1, which doesn't support it I'm told.

This card is used in some test equipment that we're duplicating, along with other NI cards (6023E's). The original digital card was a 6527, but the web site suggested that the 6514 should be used instead. It never mentioned that we'd need to upgrade our software too!

I'd like to suggest that the website makes it clear which products are only supported by DAQmx, and hence that 'old' LabView and LabWindows environments (i.e. before version 7) just will not work.

For more information on the software and hardware requirements of DAQmx, see http://digital.ni.com/public.nsf/websearch/8DFD2C9085ACB5FC86256D2600817F77?OpenDocument

Hi Mike,

All new cards released will initially only be supported by DAQmx. DAQmx will at some point in the furture completely replace Traditional DAQ. For info on individual boards and which drivers support them goto:
