Hello,
I need to use PXI-5105 with external clock and external digital trigger. Since 5105 only has 1 PFI input on the front panel (PFI1), I decided to use it to input external clock (10MHz) and route the external trigger through another PXI board front panel input, namely "AI Start Trigger" input (PFI0) of the PXI-6133 board. I use Labview VI "DAQmx Connect Terminals" and select PFI0 on 6133 as a source and PXI_Trig0 on 5105 as a destination. I configure 5105 with PFI1 as clock timebase source and RTSI0 as digital reference trigger source.
This setup worked fine until I powered down the system, installed a new PCI-5922 board on the PC and turned it back on. Now from the looks of it the 5105 does not see the trigger routed as described above when it fires. I do not get any error messages from Labview BTW.
I'm using the following hardware and software:
PXIe-10262
PXIe-8370
PXI-6133 in slot 5
PXI-5105 in slot 8
PCI-5922
Labview 8.20
NIDAQmx 8.3
NIScope 3.2
Fedor.
