This is a signal input from the outside. The trigger interval should be shutter speed (DIP switch) + 1 field
+2H period or more. The trigger interval shorter than described above cannot be ensured. If a trigger pulse is not input under the prescribed conditions, the normal operation is engaged several V after a change in input operation under the prescribed conditions.
As shown in the table on page 7, exposure time Te is determined by the setting of a DIP switch.
The normal operation state is engaged when the high period exceeds 1/3 sec. After that, the external trigger shutter operation is engaged when the trigger pulse goes “low”. In this case, the area between the falling edge of a trigger pulse and the subsequent 50 ms period is an external input inhibition area. During the trigger inhibit period, an input trigger may be missed.
After a period set by a DIP switch from the rising edge of the trigger, an image is output.
