NI PCIe-1430 software trigger ??

[inovatix]

Hi,

I need to start an acquisition from a NI PCIe-1430 frame grabber.  So far I used to trigger the start of the acquisition from the external "trigger in" SMA connector using another NI board (NI PCI-6123) to generate the trigger pulse. From now, I want to eliminate the PCI-6123 but can't find how to trigger the frame grabber in a "software" manner.  I read about the RTSI connector but this would require some hardware to be connected so I don't think this can help me.

Is there anyone that can help me to find out a way to do it wright without re-writting everything?

I included snapshots of my code.

Thank you for your help

inovatix,

I assume you are trying to trigger over the camera control lines. If so, you might check out the following KB: http://digital.ni.com/public.nsf/allkb/4FC0695C6489E11C8625716A0024AF4D

It describes how to send pulses over the camera control lines without external signals.

Hi, and thank you for your answer,

In fact, what I am trying to do is not to control the camera but it is to start-stop the acquisition on the frame grabber without the use of the external SMA Trigger In connector that is on the frame grabber.  So far i've been using this connector to recieve a signal generated by another NI device that starts the grabbing sequence. This sequence stops by itself after a predefined number of frames.

I want to eliminate the part of the code where I wait for an external rising edge on the frame grabber SMA Trigger In connector and replace it by something else that is software.  That's where I need some help.

The KnowledgeBase article I linked above should accomplish what you are after. No change to your configuration should be required; it allows you to manually send a pulse over the trigger line from a software command rather than wait for an actual external trigger.
