Hello Swetha,

Thank you for contacting National Instruments.

To configure Tasks in DAQmx Base, you can must use the DAQmx Base Task Configuration Utility. You can access this in LabVIEW by selecting Tools >> NI DAQmx Base Task Configuration Utility.
You can also access this from the Start Menu by selecting All Programs >> National Instruments >> NI DAQmx Base >> NI DAQmx Base Configuration Utility.

In this Utility, you select the devices to be used, channels to read/write, and timing parameters.

You can view examples using DAQmx Base at C:\Program Files\National Instruments\NI Daqmx Base\Examples.

Let me know if you have further questions.
