Sounds like you are interested in triggering two DAQCard-5102. The triggering capabilities of this card are outlined in Chapter 4 of the DAQScope 5102 User Manual:

One thing to point out is that RTSI lines are not available in the PCMCIA version of the 5102.
If you have any further questions you can always request support from National Instruments at ni.com/ask
