We use DAQmx library previously (from within C++) to synchronize 2 M-Series or 2 E-Series cards.
I tried to apply the same calls for the 2 NI-9205 units but get error code of -200452 (propoerty not supported).
Extract of the function calls is below:
// Create the task
DAQmxCreateTask
// Set the range for channels
DAQmxCreateAIVoltageChan
// Set the timing of the board
DAQmxCfgSampClkTiming
// For master board - M series (this gives the -200452 errors)
DAQmxSetRefClkSrc(taskHandle,"OnboardClock")
DAQmxGetRefClkSrc(taskHandle,str1,256)
DAQmxGetRefClkRate(taskHandle,&clkRate)
// For slave boards - M series
DAQmxSetRefClkSrc(taskHandle,str1)
DAQmxSetRefClkRate(taskHandle,clkRate)
// For master board - get the channel name for ai/StartTrigger
// For slave boards - set the ai/StartTrigger
DAQmxCfgDigEdgeStartTrig(taskHandle,trigName,DAQmx_Val_Rising)
// For all boards - start the task
DAQmxStartTask (taskHandle)
// In a loop called every nth seconds...acquire the data...
DAQmxReadAnalogF64
Could somebody please provide the appropriate calls needed for the master and slave devices for the NI-9205 units on cDAQ-9188, so I can test it and apply the changes to my application.
Any help would be greatly appreciated.
Thanks in advance.
