I apologize if these questions are already answered but I could not find them.
Now, I have a NI DAQPad-6015. I want to collect 30 samples of an analog signal and a want the sampling to be triggered by an external trigger at channel PFI 0. This I can do. But at want the 30 samples to be collected only after another external trigger signal has been received (the samples before this are just nonsense). It seems that this should also not be a problem, I just use Task Triggering to start my data collection. However, this second internal trigger needs to go in somewhere (like channel PFI 1 - PFI 9). PFI 0 has a BNC connector on the front of the DAQPad as does AI0 - AI 7 but there are none for PFI 1 and above. I guess one of the 30 pins correspond to PFI 1 but how do I know which one? Is there table or diagram to tell me which pin corresponds to which channel?
If someone has another solution to my problem feel free to share it with me.
