DaqMx two digital output module synchronisation

[Labview_user94]

Hello,

How Can I synchronize (Hardware synchronization) between two digital output modules using a digital input trigger

(it means that the digital input module is the master and the two digital output modules are slaves)

I am using C series modules on a compactdaq

Thank you

I've done it using a "wire" (in my case, stranded copper covered with a plastic insulation, bared at the end and connecting a Digital Out terminal to two Trigger Inputs).  If your DAQs are triggered, you simply take your Digital Out and give it a True (to make it go High), wait a msec, then make it go low.  If your "triggered DAQ" devices were wired to start on "Rising Edge", they will both start when you send the True to their Trigger DO.
