Synchronizing two PXIe in one Chassis

Hello,

I would like to synchronize a PXIe 6356 (connected to a BNC 2110) and a PXIe 4492, which are installed in the same chassis. Since I unfortunately couldn't get it to work, I wanted to ask if someone could help me with my problem.
With synchronous I mean: The measurements of both PXIe should start at the same time and should take out the measured values at the same time. Possibly it would work with a digital trigger, but unfortunately I don't know how to implement this in Labview and how to wire it. So at least I know that the PXIe 4492 has a PFI0 socket. The BNC 2110 has much more digital connectors. Please find attached my VI.

Thanks for the help in advance.

You will have to setup the triggering, similar to the snippet below. I don't have those DAQs, so I can't test it.

Edit: You might have to do SW trigger, Each DAQ will have its own trigger source (PFI0), and the software will generate a transition on both lines.

      X scale: Minus values to zero
      By merhydin
      Hello everyone!
       
      I am trying to write a program which would allow to show on x axis (time) chart values from for example: -200 s to 0.
       
      I would like each new data (1D array double) to have position 0 and earlier data to be shown as something what happened in the past. 
       
      Unfortunately I did not have any idea how to do it. 
       
      I will be very grateful for each hint.

      How to synchronize a PXI-6541 with 2 PXI-5412
      By spaghetti_developer
      Hi guys,
      I have to develop a software that has to control a waveform generation using a PXI-6541 and two PXI-5412. The first board has to generate a digital data syncronized with the arbitrary waveforms which will be genereted by the other two. Can someone tell me what is the best method to use to synchronize the three boards? Which is the best board to use as master on the clock source?
      Can MAX 5.0 simulate this hardware?
      Thank you in advance.
