External Digital Trigger to triggeracquisition using a Lab_PC-1200/AI DAQ and programming in Visual Basic

[Hubert999]

How can I use an External Digital Trigger to trigger (at about 1kHz) acquisition using a Lab_PC-1200/AI DAQ (and a BNC-2090) and programming in Visual Basic?

I have connected the external Digital triggering signal that I want to use to the PFI0/Trig1 bnc connection of my BNC-2090.

I have tried to Configure CAWI1 such as :

CWAI1.StopCondition.Type = cwaiHWDigital

CWAI1.StopCondition.Source = "PFI0"

CWAI1.StopCondition.Mode = cwaiFalling

But it does not work. I do not think that it recognize the channel PFI0. Is it the wrong name to call the channel ?

Thank you very much.

Hello,

The Lab_PC-1200 name for trigger should be EXTTRIG instead of PFI0.  The manual for this product is located here.  What is the error saying?
