I have 2 MCC 172 DAQs and would like to synchronous scan now, but there are only examples with external triggers. So I modified existing example like attached code, and test without external trigger. But it seem DAQs have different start time (Figure 1). I used BNC distributor so blue and green graph on Figure 1 have same input. Additionally, blue graph is data from device #0 (Master).
Is there any way to start DAQs simultaneously without external trigger or just code is wrong?
