Connecting an external digital trigger to a DAQPad 6015

[Nial H]

Hi. Im trying to externally trigger a series of concentration probes that I have connected through the DAQPad 6015 and on to LabView.

I do not have any external ports on my DAQ device for receiving a trigger signal and so I am trying to connect it through the screw ports that are available.

However, I have never done anything like this before and have come a little unstuck.

I just want the probes to start acquiring information once they receive a 5V rising edge signal from an external piston.

Any help that you could give me regarding connecting the system up, would be greatly appreciated.

Thanks

Hi Neil,

You need to setup triggering in your LabVIEW application and then use the trigger line you have setup in your application to wire in the trigger signal. We usually use PFI0, Attached is an example program that reads in 5 voltages from a DAQpad-6015 on Dev4 and then triggers on PFI0 on a rising digital edge.

To find the pinout of the 6015, you need to go to MAX >> Devices and interfaces >> NI-DAQmx >> DAQpad 6015
Right-click select Device Pinouts.

Hope this helps
