How to Triger for frame start in dalsa spyder 3

[Chauhan]

Hello Everyone.

I have dalsa spyder 3 SG11 line scan camera which is GigE compatible. I am able to use this camera with labview but i am unable to trigger it externally. Actully i want to give an external trigger to start a frame such that the frame is started with the rising edge of the trigger. I do not see any attribute such as frame trigger in attribute tree which could be configured to trigger a frame start. Though i am able to do a frame trigger using the dalsa GUI a screen shot of which is attached. Can anyone please help me by suggesting me changes that i shuold make in the configuration through MAX in IMAQ devices so that i can trigger a frame start. For an idea of the attributes that i see in the camera attributes i am attaching a vi that shows the attributes available for me to change.

regards

Hi chauhan,

The Dalsa utility uses a completely different mechanism to configure the camera than the standard GenICam XML interface that is specified by GigE Vision. Their utility sends proprietary serial commands to the camera (the same as their cameralink models) while IMAQdx sends register read/write commands using GenICam. This is why their software presents a completely different interface than what you see in IMAQdx.

The original implementation of the SG-11 had many issues in their XML file which made configuration very erratic and also configuring the triggering settings was very non-intuitive. You would likely have to work with Dalsa to have them walk you through how to enable the specific triggering mode you want.

HI Eric

Thanks for this. But just one more thing. Actually Dalsa GUI gives me the choise to save the setting to XML file. When the camera is started from the MAX it loads settings from XML file. Is it possible to change the location of this file or in other word if i would like to chnage this file how would i do it.

Hi Chauhan,

Those would be two different XML files. The GenICam XML file is a file that describes the camera's behavior, not the actual values of any settings. The Dalsa GUI's XML file is likely their own format for saving settings - this would likely be comparable to the ICD files that IMAQdx saves when you click Save in MAX, although of course completely different... 🙂

Thanks Eric for this information.
