Figure4-12. RTSIBus Trigger Lines

TheRTSI bus clock line is a special clock line on the RTSIbus that can onlycarry the timebase of the master to the slaves.For the smallest jitterbetween measurements ondifferent devices, you should configure theslavesto use the RTSI bus clock from the master NI 5102.♦NI5 102 (PXI)The NI 5102 (PXI) usest heP XI Trigger<0..5> to carry RTSI Trigger<0..5>and uses PXI Trigger 7 to carry the RTSI clock signal to all otherPXI slots in the system. RTSITrigger 6 is reserved for use with PXI StarTrigger,which the NI 5102 can receive but may not drive.
