What is the procedure to initialize and use RTSI clock (7) signal?

[Graziano]

I need to synchronize the timebase of my NI6251 to an external clock, through RTSI. Do I need some special driver? Or some initialization procedure need to be used? Do I need to include some file????

Note, I'd like to avoid use of MAX, if it is possible I want to do all my stuffs as C code.

Thanks!

Hi, take a look at this document.

and to this answer (seems related, isn't it? 😉

All samples are LV block diagram, but remind that DAQmx parameters and function names are similar in LV and in LW.
Also remind that you could have problems connecting high frequency clocks to RTSI/PFI lines, I suggest not to go higher than 20Mhz.
If you don't find your answer, describe a little more deeply your application's needs and we'll think about it together!

Regards.
