Hey Clinton, From the <a href="
http://www.ni.com/pdf/manuals/372411a.pdf" target="_blank">PXI-8104 User Manual</a>, you will find the following: "The SMB connector on the NI PXI-8104 front panel can connect to or from any PXI backplane trigger line. A trigger allocation process is needed to prevent two resources from connecting to the same trigger line, resulting in the trigger being double-driven and possibly damaging the hardware. At the time of this manual’s publication, this software is not yet available for Windows." Therefore, this functionality has not been implemented yet. If you would like to file a product suggestion on this please feel free to go to <a href="
