X-series PCIe to X-series PCIe syncronization on the same task Labwindows CVI

Hi

i have a single task that uses 2 X-series cards PCIe 6363 with a RTSI cable connected.

i made exported signals to start triggers to connect and run both cards. i looked in the examples for multi device synchronization and it lists other devices e,m,,s series but nothing is listed for x series.

when i run the application it works with just the start trigger no errors, but i am curious that in the manual it says to take the master card and export the source clock and route it to the slave card and back to the source clk. if there is any documentation or specific example in CVI that references this please attach
