The PXI-5411 is capable of Phase-Lock Looping with the 10MHz Backplane clock and is capable of receiving a trigger signal from the PXI Star Trigger line. However, the PXI-5411 is not capable of driving the PXI Star Trigger.
For more information abotu how the PXI-5411 uses the PXI Trigger Lines, see the "RTSI/PXI Trigger Lines" part of "Chapter 2 - Arb Operation" in the User Manual of the board
The Example program attached below (written under LabVIEW 6.1) shows how to synchronize two NI 5411 boards by first Phase-Lock Looping (PLL) their internal clocks with the 10MHz Backplane Clock provided by the chassis, and then sending a trigger line from one 5411 (the master board) to the other (the slave board).
If you want to receive the PXI Star Trigger as the Star Trigger, you will need to use a PXI board capable of sending a signal to this pin. The only NI PXI boards capable of sending a digital trigger pulse over the PXI Star Trigger line are the PXI-5112 (High Speed Digitizer) and the PXI-7344 (Motion).
The PXI-6608 board is not capable of driving the PXI Star Trigger line, however, if you install the PXI-6608 board in slot 2 of the PXI chassis, it will override the 10MHz clock signal provide by the PXI chassis, with the onboard OCXO 10MHz signal provided by the board itself. The PXI-6608 provides a 75 ppb accuracy 10MHz clock, that replaces the aproximately 50 ppm accuracy 10MHz clock provided by the PXI chassis. By overriding the 10MHz clock with a better accuracy one, the PXI-5411 boards will do PLL using a better reference clock.
The only device that PLL automatically with the 10MHz backplane clock are the PXI-6115 Simultaneous Sampling boards.
