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 trigger input inhibition area. During the trigger inhibit period, an input trigger may be missed. *4: Be sure to input an external VD signal between 10 µs and 75 ms from the falling edge of a trigger pulse (as shown by 1 and 2 in the figure). For the input (except described above), the operation cannot be ensured. If the external VD signal is not input under the prescribed conditions, the normal operation is engaged several V after a change in input operation under the prescribed conditions. *5: When the external trigger shutter mode changes into the normal operation mode, one WEN signal is output. Note : An image is superimposed when the next exposure ends before the previous image is output. 23

TIMING CHART OF EXTERNAL TRIGGER SHUTTER - MODE 1

For setting the shutter speed using TRG width
HD/VD input
Continuous HD input and single VD input
*
1:
This is a signal input from the outside.
Be sure to input both HD and VD signals in this case.
Make the
phase of the VD signal coincide with the falling edge of the HD signal during input operation.

(The trigger width should be between 2

*
3:
The normal operation state is engaged when the trigger 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 trigger input inhibition area.
During the trigger inhibit period, an input trigger may be missed.
*
4:
Be sure to input an external VD signal between 10
μ
s and 75 ms from the falling edge of a trigger pulse (as
shown by
1
and
2
in the figure).
For the input (except described above), the operation cannot be ensured.
If the external VD signal is not input under the prescribed conditions, the normal operation is engaged
several V after a change in input operation under the prescribed conditions.
*
5:
When the external trigger shutter mode changes into the normal operation mode, one WEN signal is
output.
Note
:
An image is superimposed when the next exposure ends before the previous image is output.
