I am using PCI-6251 for digital output , i want to acquire two D-Outputs. one must be protection for another, kind of overlap.
Must start before another and end after another. How to do it in labview. i have attached the images of what i want .

Hello @pratheesh31,

Its Quite Possible and it should be handled Programmatically by switching (Digital ON) after the another and Switching (Digital OFF) before the other.

The 6251 does support digital waveform generation and acquisition on port 0   So, for Digital output you would create a Task with 2 lines, write a 1D array of digital waveforms to the device buffer and start the Task.
