cDAQ9188 in C

[ASIM_BHATTI]

Hello all

I am trying to run cDAQ9188 with 03 NI 9205 modules installed on it in single task (for auto synchronization) using C APIs given by NI. For single NI 9205 module installed on cDAQ9188, following works fine:

.........

DAQmxErrChk (DAQmxCreateTask("",&masterTaskHandle));

DAQmxErrChk (DAQmxCreateAIVoltageChan (masterTaskHandle,"cDAQMod1/ai0:31","",DAQmx_Val_Cfg_Default,-1.25,1.25,DAQmx_Val_Volts,NULL));

.........

When i install all 03 modules, i get cDAQMod1,cDAQMod2,cDAQMod3 device names. How should i define all three devices in "DAQmxCreateAIVoltageChan" API so that i can acquire all 96 channels in single task (with auto synchronization of three modules)?

Thanks

Best Regards

Hi Asim, 

I'm not certain, but I beleive it may be similar to:

DAQmxErrChk (DAQmxCreateTask("",&masterTaskHandle));

DAQmxErrChk (DAQmxCreateAIVoltageChan (masterTaskHandle,"cDAQMod1/ai0:31,cDAQMod2/ai0:31,cDAQMod3/ai0:31","",DAQmx_Val_Cfg_Default,-1.25,1.25,DAQmx_Val_Volts,NULL));

Let me know how this works.
