Good news that this is hopefully an easy fix.  I am away
from my daq computer so I can't answer your specific
questions about versions (I will add that in a couple of hours).

In the meantime, if I set "ai.ClockSource = 'External'" I
receive an error message that this is not a valid option. 
When I look at all the settings and options for this board,
External is not on the list (the other NI parameters as on
the ClockSource help page are options, e.g., ExternalScanCtrl). 

In terms of the getdata problem, I just get a timeout error.

Am I thinking about this the right way?  I thought that all
I needed to do is hook up the PFI0 pin connectors to each
other from the two boards and read the clock from one board
to the other. Because I can't do a HW digital trigger due to
my need to collect pretrigger data, I think this is my only
option.
