Timeout error with external triggering

HI,

 

               I am using redlake ES2093 camera for capturing TV pattern images using apptern generator. I am using the vsync signal(60Hz) output from the pattern generator for triggering the camera.  I have PCI 1428 card for camera.I have done following settings in the MAX

 

 

           Output format   = Single Tap 

           Trigger Source = External BNC (since I am applying the VsYNC signal to camera head as triggersource)

           Trigger Mode    = Edge controlled

           Integration time = 16 ms.

           Gain                   = 1db

 

When I Click the grab option I can see images.

 

Now I have few questions here. If I am getting images in both snap and grab with these settings, does this mean my caemra is triggered??

If NO what should I do to check that.

If YES, When I change the intgeration time above the 16 ms I get timeout error. I tried increasing  the frame timeout. but it's not working.

Help Me.

The fact that you see a timeout confirms that you are in triggered mode. As an easy test, just disconnect the trigger line and see if you get a timeout.


Since you are using a 60 Hz VSYNC signal, your camera gets a trigger every (1000 ms/60) 16.666 ms. So when your integration time becomes longer, you get a timeout as you miss the next trigger pulse. Dont increase the integration time unless, you see a bad image and certainly keep it under 16 ms.

 

Hope this helps.
