Finally I understood RTSI lines (or at least I think so).
I am using a PXI Chassis with 3 PXI Cards (5122, 6120, 6250)..
I want to start a measurement when a certain condition is met. I want to measure with all three cards at once. Therefore I thought of using RTSI Trigger Lines.
I added a NIScope Export Signal VI and selected PXI Trigger Line 0 / RTSI 0 as output terminal. Now, when I want to use this signal as Trigger Input for the DAQmx devices (DAQmx Start Trigger Digital Edge) and when I add a constat to the source terminal, I get a quite long list.
What confuses me is, that each card has its own RTSI Lines. I get: /5122/PXI_Trig0, /5122/PXI_Trig1, ... and for the 6120 I get as well: /6120/PXI_Trig0, /6120/PXI_Trig1, .... AND I also get /5122/PXI_Trig0, ...
Now I was wondering if /5122/PXI_Trig0 is the same as "PXI Trigger Line 0/RTSI 0" which I can choose in the Export Signal VI and why do I see all those lines, if they all belong to all cards?
I hope you know what I mean
Thanks in advance
