Hello;
I'm not familiar with the TDC DAQ card, but, in case you have the board documentation stating what DLL function calls need to be made in order to execurte a DAQ task, you can use the Call Library Function of Labview to execute the functions.
You will need to execute all functions needed to accomplish the DAQ task in a sequence structure, to make the function calls in the necessary order.
Hope this helps.
