I am now attempting to recieve signals from 4 boards synchronously. Using the attached VI, if I set two boards to operate from an external reference and two others to use MIMO, I receive an error at the Initiate vi that ~The reference clock PLL did not lock within the alloted time. However, if I only use MIMO on one board and operate the other three boards off an external reference the VI works fine. Am I missing something?

I realized I forgot to save the values I was using as defaults, so it probably was not very clear how I set up the boards.
ch0 was connected to ch1 with a MIMO cable, ch3 was connected to ch2 with another MIMO cable.
External references for RefIn and PpsIn was connected to ch1 and ch2.
When I run the VI, I get the error I mentioned before about the pll not locking. However, I am certain that there are no problems with the external reference as the VI works fine if I connect all four boards to the external reference without using the MIMO cable. Also, the VI can synchronously receive from two boards without any errors using a MIMO cable. As such, I was wondering whether there was anything I need to be aware of in the case when there are more than one master each with its own slave.
