How syncronize PCI4472 with cDAQ-9172?

[leocavadas]

I need syncronize the acquisition of 32 channels from PCI-4472(8 channels) and rack cDAQ-9172(16ch-9233(4modules) + 8ch-9234(2modules)). I tried several arranges but dont get to do work. I have a 9263 auxiliar module if necessary.

Can anyone help me? A second problem when i do the aquisiton without syncronize is get waveforms with differents DTs between devices.

VI in attached. Thx.

Hi Leonardo,

to use trigger from cDAQ-9172, you need an additional hardware-timed digital module to access the PFI lines. The hardware-timed digital module must be installed in slot 5 or 6 to access the PFI lines. 

Thus, you can use PFI line from PCI-4472 to synchronize your measurements.

I hope I help you.
