Figure 4-12. RTSI Bus Trigger Lines
The RTSI bus clock line is a special clock line on the RTSI bus that can only
carry the timebase of the master to the slaves. For the smallest jitter
between measurements on different devices, you should configure the
slaves to use the RTSI bus clock from the master NI 5102.

♦ NI 5102 (PXI)
The NI 5102 (PXI) uses the PXI Trigger <0..5> to carry RTSI Trigger
<0..5> and uses PXI Trigger 7 to carry the RTSI clock signal to all other
PXI slots in the system. RTSI Trigger 6 is reserved for use with PXI Star
Trigger, which the NI 5102 can receive but may not drive.
