  • NI-9237
  • cDAQ-9181
  • PCIe-6323

Issue Details

I have a PCI(e) input module, and a C series cDAQ module. Can I synchronize the two devices using DAQmx?

Solution

The answer depends on what level of synchronization you require. You will be able to achieve software synchronization, which will start both devices' tasks at the same time in software. However, this is a non-deterministic method, as there are many processes that run on your OS that may delay the true synchronization of the two tasks. 

Additional Information

If tighter synchronization is required, look into moving all devices to the cDAQ or PXI platform in order to utilize hardware features such as trigger and clock routing.
