Another thing to add, I was able to run the the NI-SYNC C API for the example routing the clocks with no errors. Here is an example code for testing the functionality of the PXI-6683H as well as for testing the routing. on line 97 and 98.
//*************************************************************
//** Name: NI-SYNC Route Triggers.c **
//*************************************************************
//Description:
//This code can route triggers from an external line to the
//backplane, or from the backplane to an external line.
//Specifically, this code will route the triggers from the
//"Source Terminal" inputs to their respective
//"Destination Terminal" location.
//HW Requirements:
//PXI-6651
//PXI-6652
//PXI-6653
//PXIe-6672
//PXIe-6674T
//PXI-6682(H)
//PXI-6683(H)
//Connections:
//Possible connection made to one or more PFI lines, depending
//on the routes.
