Issue Details

When deploying a VeriStand project using PXIe-6738 or PXIe-6739, I receive the following error:

Error -89136 occurred at Project Window.lvlib:Project >> Project Window.lvlib:Command >> NI_VS Workspace ExecutionAPI.lvlib:NI VeriStand - Connect to

Possible reason(s):

Specified route cannot be satisfied, because the hardware does not support it.
NI VeriStand:  DAQmx Control<append>
Property: RefClk.Src
Requested Value: /Slot5_6739_AOwRatiometric/PXI_Clk10

Task Name: Slot5_6739_AOwRatiometric_AO



The default PXI Backplane Reference Clock is 10 MHz, which cannot be used as reference clock for the NI PXIe-6738/6739.
To solve this error, set the PXI Backplane Reference Clock to 100 MHz implicitly for the PXIe-673x device.
