DStarB vs Star vs Trigger

Hello,

 

What is the difference between the DStarB, PXI_Star, and PXI_Trigger lines? Are they all attached to the same line? I know that DStarB is length matched to all slots from the timing module which sounds similarly to what the PXI_Star does (https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z000000kIswSAE&l=en-US). I imagine the PXI_trigger line is also just a trigger that isnt length matched?

 

I ask all this because I have a VI that takes in two different triggers (DStarB and PXI_Star) from the 6674T and sends them to a 7972 FlexRio. For some reason when I trigger the DStarB, it triggers both; what it does and what the PXI_star does while the pxi_star only triggers pxi_star. Is this normal behavior? Is the DStarB attached to all the triggers of the FlexRIO?

 

any insight would be appreciated. Thanks
