Cannot send software trigger using NI sync and 6682

[jakidd]

I cannot send a global software trigger to the PXI trigger (PXI_Trig0) using the PXI-6682 card and NI sync software (3.0 and 3.1 beta). I ran the example vi: Route Software Trigger.vi and selected my 6682 resource, and destination terminal PXI_Trig0. I get the error: -1074118606 occurred at niSync Connect Software Trigger.vi, Driver Status:  (Hex 0xBFFA4032) The specified source terminal is invalid for this operation. Looking at the source terminal it is selected as GlobalSoftwareTrigger. If this card does not support a software trigger (I can't imagine why), how else can I send a software trigger to the PXI trigger backplane?

Any help would be great.

I figured this one out. Apparently the PXI-6682 card cannot do a software trigger, so I internally connected PFI2 to PXI_Trig0, then setup a time event (low,high,low) on PFI2. The time event will fire a trigger on PFI2 which fires a trigger on the PXI backplane PXI_Trig0. I will then set this up to fire all the star triggers instead of PXI_Trig0 to sync up my two FPGA's.
