How do I trigger Analog Output and Digital Outout Tasks Starts off of a Counter Start?

[neuronerd]

Hi,

I am trying to sychronize the start of an analog output task, a digital output task and a counter task. I want the counter's start to serve as the master trigger and the analog and digital tasks to sync to its start. 

I am assuming I need something like:

analogOutputTask.Triggers.StartTrigger.ConfigureDigitalEdgeTrigger("???", DigitalEdgeStartTriggerEdge.Rising);

digitalOutputTask.Triggers.StartTrigger.ConfigureDigitalEdgeTrigger("???", DigitalEdgeStartTriggerEdge.Rising);

analogOutputTask.Start(); // slave 1

digitalOutputTask.Start(); // slave 2

counterTask.Start();n // master

Where ??? is a string specifying the counter task's start trigger source. However, I cannot seem to find what this string is. Any suggestions?

Thanks!

Hi Jon,

I believe that the string that you are looking for is going to be something like this:

/Dev1/ci/StartTrigger

Instead of using Dev1, you should use the actual alias name of your device in the Measurement and Automation Explorer.

Just, FYI, the solution to this problem as well as some other ones is encapsulated in a short .NET example I created. It is located on the NI website:

This project shows how to synchronize all your analog/digital outputs across tasks and boards in terms of start timing and clock synchronization.
