Synchronization some PXI Boards

[ana_hg]

Hy!
I have to program with C following boards: two PXI-6602 (Counters), one PXI 8461 (CAN) and one PXI-6220(multifunction DAQ Device). All of them have to work at the same time. Which is the best way? Which functions of the dll libraries shall I have to use?

Thank you!

You can synchronize multiple boards via the PXI-Backplane of the PXI-Chassis. You could for example route the Sample-Clock of the 6220 to all the other cards, so that they all use the same sample clock.

There is an example installed with the DAQmx driver (7.3) that synchronizes multiple boards. You can find it in the National Instruments-folder under the following path:
