1: This is a signal input from the outside.  Be sure to input both HD and VD signals in this case.

(The trigger width should be between 2 

µ

s and 1/4 s)

*

3: The normal operation state is engaged when the trigger high period exceeds 1/3sec. 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: In all cases the WEN signal indicates when a valid image is available. Normally, an image is output after

the external falling edge. If the falling edge of the trigger is very close to the falling edge of the external VD,
there may be a delay of 1VD in the output. The period of uncertainty is when the falling edge of VD is
between 65 

µ

s before or 10 

µ

s after the falling edge of the trigger.

*

5: When the external trigger shutter mode changes into the normal operation mode, one WEN signal is

output.

 : An image is superimposed when the next exposure ends before the previous image is output.
