how to synchronize AI and AO with software on PCI 4452 and PCI 6731

[ciccia]

Hi,

we have two traditional NI-DAQ devices. We want to synchronize the acquisition on AI device (PCI 4452) with the shot on AO one (PC 6731). How can we do?

Hi, you can use the following example:

Synchronizing Two PCI DSA Devices with CVI in Traditional DAQ

The Select_Signal function routes the In_Start_Trigger signal from the master board to a RTSI pin. Select_Signal connects this RTSI line to the trigger circuitry of the slave board." So using Select_Signal function and the Start_Trigger signal you can syncronize via RTSI your board. Best Regards AmbuA
