Why is delay in AI Start is ignored?

[David Huggins]

I'm trying to delay my post-trigger data acquisition by using "Delay" in the additional trigger params input of AI Start.vi. Experimentation shows the digital trigger is working but AI Start ignores my delay - in fact, wiring up an indicator to "Actual Trigger Params" shows the delay is set at 0 seconds no matter the input. I'm using a DAQpad and LabView 5.1.1.

Greetings,

Unfortunately, E-Series DAQ devices do not support this feature (only the 2000 Series devices do). To implement a digital trigger delay, you will need to incorporate one of the counters from your board into your program. Below is a link to an example program, which demonstrates how to implement this functionality:

Good luck with your application.
