TIMING CHART OF EXTERNAL TRIGGER SHUTTER - MODE 2
(RESET MODE)
For setting the shutter speed using TRG width
*
1: This is a signal input from the outside. The trigger interval should be trigger pulse width + 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 ensured several V after a change in
input operation under the prescribed conditions.
*
2: Exposure time Te Te = Trigger width + 97 µs (XC-ES50/ES30, XC-EI50/EI30),
Te = Trigger width + 120 µs (XC-ES50CE/ES30CE, XC-EI50CE/EI30CE)
(The trigger width should be between 2 µs and 1/4 s)
*
3: 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.
*
4: A VD signal is generated 1H to 2H after a trigger pulse falls, and an image is output in synchronization with
the VD signal.
*
5: When the external trigger shutter mode changes into the normal operation mode, a WEN signal is output.
