Use the PCI-6503 to "start" button which triggers my own Test Sequencer?

[NezaGC]

I am using the Measurement Studio 6.0 and Visual Basic 6 to program my own Test Sequencer and I want to use the PCI-6503 PortC, Bit0 to "start" the sequencer.

My main interest is to use hardware triggers to avoid VB6 timers.
Which objects I must use to enable external triggers and how to configure property pages?

Best Regards

Hi Neza,

It sounds like you are trying to acquire a digital input using a start trigger in Visual Basic.

When you installed the NI-DAQ 7.4 Drivers there should have been some examples installed that are located in this path:
C:\Program Files\National Instruments\NI-DAQ\Examples\VBasic\Di

If you look in this folder you can find some examples that show how to do device triggering. While some of the examples are written for different boards you will see how the triggering is performed in VB.

Regards,
