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
QUOTE (ptit bras @ May 18 2006, 01:02 PM)  have you tried to test your board with more simple aquisition task ? 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 : http://zone.ni.com/devzone/conceptd.nsf/we...256FB1007227EC). The fact that triggering doesn't work is more surprising. Did you ever tried synchronising or triggering with mac os x ? Boris This post has been edited by tibobo: May 18 2006, 01:48 PM
