gasguy,
That is because only certain boards (mainly E Series and SCXI) are currently supported under NI-DAQmx 7.0. In future versions of the driver, support for more boards will be added. Refer to the NI-DAQ 7.0 Readme File for a list of supported hardware or click on this link: http://www.ni.com/support/daq/versions.htm. Have a great day!
