1 This is an external input signal. Make sure to input

both HD and VD signals.
 2 The shutter speed (Te) is determined by the setting
of DIP switches.
For details, see page 23.
3 Normal operation is resumed when the trigger pulse

width is 1/3 s or more. The trigger falling edge
restores external trigger shutter operation. At this
time, the 50 ms after the falling edge of the trigger
pulse is an external trigger input inhibition area.
There is no guarantee of operation for any trigger
input in this period.

 4 An image is output when an external VD signal falls
10 ms or more after a trigger pulse rises ( and 
in the figure). If the period from the trigger rising
edge to the external VD falling edge (T in the
figure) is under 10 ms, it is not defined whether the
image is output for the external VD falling edge or
the image is output for the next external VD falling
edge. ( in the figure shows that the image is
output for the next external VD). In this case, see
WEN since the image and WEN make up a pair.
Note
An image is not output correctly when the next trigger
is input before the image for the previous trigger has
been output.
