Start trigger 6608

[Sirenko Alexander]

Program works in CVI 8.0

I use several 6225 for analog acquisition and one 6608 for time metering.

For simultaneous start of all devices start trigger must be set up.

DAQmxCfgDigEdgeStartTrig function allows me to connect ai\StatrTrigger of "master" 6225 with PXI_Trig0 and to connect ai\StartTrigger of other 6225 with DevN\PXI_Trig0.

So, one of 6225 defines strarting others devices 6225. For complete syncronization I must tune up start of 6608. This mean, that I shall connect PXI_Trig0 with DevN\Ctr0StartArmTrigger, where DevN - name of device 6608 in system.

What function must be applied for it? Maybe I need fundamentally other method of syncronization?

Best regards, Alexander

Hi Alexander,

To define the source terminal of the Arm Start Trigger in LabVIEW, use the DAQmx Trigger Property Node (see attached image).  The C function for the same operation would be DAQmxSetDigEdgeArmStartTrigSrc().  Is this what you're trying to configure?

I think it's what I need.

I'll try to use it, thank you for help, Andrew.
