I am not sure whether I should use ND_IN_SCAN_CLOCK_TIMEBASE or ND_IN_CHANNEL_CLOCK_TIMEBASE, have no idea about these things. Where can I find details about these signals? So will this works? BTW, the download for NIDAQ6.9.1 is not complete with the function reference manual, mis sing all the bmp files. (ftp://ftp.ni.com/support/daq/pc/ni-daq/6.9.1/Nidaq69.EXE). I do need a complete one. Thanks for your time.
I'm attaching an example C++ code which does the synchronization of analog input of two E-Series board trough RTSI. That example can be applied to PXI as well. Counter 0 is generating the pulse train which will be used as scan rate to both boards. You can refer to that example to see how the select_signal function is used to accomplish that task. Hope this helps. Filipe
