Do you mean an external digital trigger signal will trigger the start of your analog acquisition from 8 channels? Or do you mean that your computer is somehow generating an IRQ (interrupt request) and you wish to catch it in your data acquisition program and start your acquisition?
Furthermore, which language do you intend to use? Both LabVIEW and LabWindows/CVI ship with many examples for triggered analog acquisition. The NI-DAQ driver also ships with examples for Visual Basic and Visual C++. If you still cannot find what you are looking for, simply use the Development Library on our website. Go to www.ni.com and click on Developer Zone. In the Development Library you will find hundreds of examples. Look in the analog input areas for triggered a
cquisitions.
