Hi,

I'm trying to use DAQ S 6143 and M 6224 simultaneously using DAQmx base.
I should admit I'm a little bit frustrated since I didn't managed to do anything !... :

- Using RTSI cable to share sample clock using daqmx base export signal vi, nothing works.
- Using "daqmx base start trigger (analog edge)" to do triggering (start an acquisition when an analog input cross a level) on a single device, nothing works. (example below).


Could somebody have any successful experience to share in the field of triggering/synchronizing on mac os x or should I abandon all my hopes...?
For now, I'll go to bed !

Thanks

Boris

have you tried to test your board with more simple aquisition task ?

Hi Tibras




Yes, I'm using simple acquisition tasks for more than one year on both boards, but without hardware triggering. Now I have to synchronize acquisition between the two cards and that's why I get to try sample clock sharing with RTSI bus. It didn't work so I tried using triggering which didn't work too .

The fact that RTSI doesn't work is not surprising for me (since it's written here :

The fact that triggering doesn't work is more surprising.

Did you ever tried synchronising or triggering with mac os x ?

unfortunately not

just continious analog acquisition…

in couple weeks, I've no time for test but later…

I keep you in touch…
