How to synchronize PCI4474 and 6601 througn RTSI

  I am a new user of DAQmx. I use 4474 to acquire virbration singal and use 6601 to acquire tacho signal.I heard that PCI 4474 and PCI 6601 can be synchronized by RTSI,but I really don't know how to  do it in details. I used the example in labview,but it can't work . Because it is used for PXI. The settings of PXI and PCI are different. Is there anyone can give me some examples. Thank you!
(Labview 7.1 ,DAQmx)

There are two signals that you can share between the PCI-4474 and the PCI-6602.  They are the start trigger and the AI sample clock.  Unlike PXI, you cannot share the sample clock timebase of the PCI-4474 over RTSI with the PCI-6602.  Here's a link to a KB which talks about different types of synchronization methods you can use with DSA and counters:
