The NI-5421 Specs Manual (http://www.ni.com/pdf/manuals/371477d.pdf) says that the PFI ports can be used to send a trigger externally. I haven't been able to find a way to do this. I want to test the potential of external triggering with my device, but for the sake of convenience I would prefer to be able to use one of the PFI ports to send a trigger to the other PFI port, for simplicity of testing (no need for additional pulse generation).
Any advice is appreciated.
Thanks,

Hi Billy,
You will be able to export things like start triggers and markers on the PFI line. Because it involves very tight timing and synchronization, it will be hard to monitor accurately a PFI as input on an FGEN device. Are you looking to confirm the output of triggers, or do you want your device to trigger itself?

You can use the niFgen Export Signal VI to route triggers on your device to the PFI line.
