Dear All,
I connect my Basler camera to matlab through GenTL toolbox.
https://www.mathworks.com/hardware-support/gentl.html
Could anyone success to enable trigger out signal of Basler camera ? Please guide me
My camera is : Basler ace acA4112-20um
It has a function to generate trigger out signal base on 'Exposure Active'.
This is mycode export from Image Acquisition toolbox.
v = videoinput("gentl", 1, "Mono8");
info = imaqhwinfo(v);
width_res = info.MaxWidth;
height_res = info.MaxHeight;
v.ROIPosition = [width_res/2 height_res/2 1280 1280];
src = getselectedsource(v);
src.AutoTargetBrightness = 0.5019608;
src.ExposureTime = 1000;
src.LineSelector = "Line3";
src.LineMode = "Output";
img = getsnapshot(v);
Thanks and Regards!

Configure camera for FrameStart trigger mode and specify external triggering signal input line and desired trigger condition.
This requires setting the TriggerSelector first; once a TriggerSelector value is selected, setting a trigger property (for example, TriggerMode to 'on') applies only to the specified trigger mode (FrameStart).

Hello, I read the original question as trying to use the camera's output line to indicate 'Exposure Active'.
I'm using a Ximea camera and would also like to use this functionality.
The question is marked as answered, but the link is to using the trigger input line, it doesn't seem to provide any insights into configuring camera output line.
Are there any examples showing the configuration of camera ouputs?
Thanks for any help,
Carl
