*1 This is a signal input from outside. Make sure to
input both HD and VD signals.
*2 The exposure time (Te) is determined by the
setting of DIP switches.
For details, see Page 14.
*3 The normal operation state is carried out when the
trigger pulse width is 1/3 s or more. The trigger
falling edge restores the external trigger shutter
operation. 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.
There is no guarantee of operation for any triggers
input in this period.

*4 An image is output when an external VD signal
falls 10 ms or more after a trigger pulse rises (2
and 3 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, there may be a delay of
1 VD in the output. (1 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.
*5 Video out 2 is output only in the 2I mode.
Note
An image is not output correctly when the next trigger
is input before the image for the previous trigger is
output.
