Shutter-Select Mode With External Trigger - JAI LQ-050CL User Manual

 If using individual exposure, the EEN signal represents the channel with the longest
exposure time
 The longest shutter operation is the same as the set trigger interval.
 If one-push auto white balance is used, using the shutter (command AH) or using the
gain (command AW) depends on applications. If the auto white balance switch located
on the rear panel is used, only the gain is effective.

Shutter-Select mode with external trigger

This mode allows the user to have full control of the exposure time, by programming a
timing generator, while the line rate is controlled by an external trigger signal. The
camera can accept an external trigger through the Camera Link connector or though the
12-pin Hirose connector.
