1: This is a signal input from the outside. The period of a continuous VD signal is prescribed as one field. Be

sure to input both HD and VD signals.

2: As shown in the table on page 7, exposure time Te is determined by the setting of a DIP switch.

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: An image is output when an external VD signal falls 10 ms or more after a trigger pulse rises (shown by 2

and 3 in the figure). If the time (T in the figure) between the falling edges of a trigger pulse and external

VD signal is under 10 ms, an image is output when the external VD signal or the next external VD signal

falls (as shown by 1 in the figure). (In this case, an image is output when the next external VD signal falls.)

An image and WEN signal are always output together. For more details, refer to the WEN signal.

Note

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