Hello Vanessa,
In some applications, when a trigger occurs after several minutes or when integration takes several seconds, the timeout parameter may be too small to wait the amount of time it takes to acquire an image. If the image you request is not ready by the timeout parameter, the acquisition code generates a timeout error.
To prevent this problem, check the acquisition status and request an image only when you know one is ready. By just checking the acquisition status and not requesting an image, you could wait indefinitely for an image without receiving an error.
