I figured it out...I needed to set the output to Reading Row to get all the entries in the buffer out.

Thank you for responding.

I am able to trigger the DAQ6500 from the SMU 2470.  I can plot the samples in the graph view in each of the units.  However, I can't seem to store the samples in the reading buffers for export (in either unit)..  This seems to work fine when I use the units individually, but not when I'm going through the  trigger-flow.  The buffers are empty (even though data is correctly sampled, since I can plot it in the graph views) - where is the data going-?--the assigned reading buffer in each unit remain empty - but, again, data is being sampled correctly (it seems) since the graphing view in the respective units displays them without any issue.  

I have a similar need.  I am using a DAQ6500 to monitor a thermocouple,  and it is triggered by an SMU measuring leakage current.  The SMU is triggering the DAQ6500 via digital IO into the  the external trigger input on the DAQ6500.  The triggering seems to be working, and I can graph the samples in the units.  However, when I look at the reading buffers, they are empty, and therefore I cannot export them to USB for further analysis. 
I can't figure out why the data is not being stored in the buffers even though the data is being sampled and displayed in the graph view.  However, if I don't trigger one unit from the other, the buffers seem to work fine.  Any ideas?
