Grays;
I'm not sure if I quite got your question, when you say acquisition and convertion, but, if you wnat to set an interrupt like acquisition, you have the option on looking at the Config_DAQ_Event_Message NI-DAQ funcion if you are programming the board by using NI-DAQ functions calls, or at the DAQ Occurence Config.vi if you are using Labview to program the board. Then you can select the type of occurence which will generate the interrupt.
Hope this helps.
