13. Ext trigger
The external trigger function is used with a frame grabber to obtain an image of an object at a desired exposure time. Settings can provide images at various timings. The exposure time can be controlled by the external trigger pulse width.
1)Trigger mode : Selects external trigger mode
•Mode 1: Use for exposure time less than 2 fields.
•Mode 2: Use for exposure time greater than 2 fields.
Note: Longer integration time tends to show increased noise and flaws in the CCD.
2)Delay time : Time from end of trigger pulse to camera sync reset
Setting range is 3 to 20 H. Can be used with a strobe light source to provide an optimum image with a frame grabber.
3)Trig polarity : Selects positive or negative trigger pulse polarity.
4)WE polarity : Selects WE pulse polarity
Selects pulse (WE) output synchronized to image obtained from the camera rear panel multi connector for 1 field or 1 frame. Use to match the interface of an external frame grabber or other equipment.
