Hello,
Ok, I see what is happening. Your original VI is written in Traditional NI-DAQ. The new M Series cards are only supported in DAQmx.
In the future, you will need to write your applications with the newer DAQmx driver to make use of your M Series card. However, since you already have this VI written in Traditional NI-DAQ, you can make use of the Traditional NI-DAQ Compatibility VIs. These VIs allow you to run LabVIEW applications written in Traditional NI-DAQ on devices that are only supported by NI-DAQmx.
These VIs can be downloaded at: http://digital.ni.com/softlib.nsf/954feaeea92d90918625674b00658b83/9d67f671bcc6850586256e630059308b?OpenDocument
Please follow the instructions on the download page to install these VIs.
Let me know if you have any further questions.
Sincerely,
Sean C.
