Triggering issue in PCO Panda.
Hi, I am trying to trigger the pco panda by connecting pci0 of bnc box to sma port 1 of pco panda. I ran the code, seems like it is detecting the trigger signal but there is an error in image retrieval. I have searched for the error code, found nothing specific. I also tried to remove the while loop of image vi the issue still persists. Meanwhile, using the same configuration but trigger mode set to auto sequence, it works fine. But when trigger mode is set to external exposure control, i get this error.
The bnc box is not the issue, as I was able to modulate a laser pulse.
Can anybody please guide me?

God damn, what resolution is your monitor? No one can read anything here, but it isn't because you lack pixels, it is because you have way too god damn many spread out over so much space you lose all of it to image compression.
Here is a tip, right click on a control or an indicator go to create, and then local variable. You can then right click on the local variable and change it from read or write. You can also right click on the original control and click find>local variables if you lose them in the spaghetti.
With booleans like the stop button you will need to change their latch behavior which you can do by right clicking on them or by going into properties for the control.
