Hi, I'm using the NI 1427 with a Goodrich 640x512 NIR camera. We are using an external source to trigger the camera and occasionally the time between trigger pulses is longer than the timeout for the camera (i have it set to 2000 ms right now). I would rather not set a 10 sec timeout period for the camera and was wondering if there was some funciton I could call before calling the imaqGrab function to see if the camera has actually aqcuired an image and was ready to be "grabbed" from. Thanks!

@FeralPhys: I think you can set the timeout period much higher. Actually, we have several projects where the timeout period is set to infinity. The obvious question is, how do you stop the grab while it's stuck infinitely in the wait and you need to stop the application. You can do this by having a parallel execution loop, which in case of stop condition closes the IMAQ session. After IMAQ session is closed, IMAQ Grab stops with an error (which you can easily handle). We are using this approach usually with IMAQdx, but I think it works with IMAQ the same way. V
