For setting the shutter speed using the DIP switches

HD/VD input
Continuous HD input/Single VD input

*1 This is a signal input from outside. Make sure to

input both HD and VD signals in this case. Input
the signal so that the VD phase aligns with the HD
falling edge.

*2 The exposure time (Te) is determined by the

setting of the DIP switches.

For details, see Page 9.

*3 The normal operation state is chosen when the

trigger pulse width is 1/3 s or more. (By entering a
continuous VD in this section, an image is output.)
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 Input the external VD within the period of 10

ms to

75 ms after the trigger rising edge (1 and 2 in
the figure). There is no guarantee of operation
when any other input is selected. If an invalid
signal is input, the input is changed to a valid
signal, and after several V signals, normal
operation will resume.

Note

Make sure that the trigger signal and the VD signal
make up a pair.
An image is not output correctly when the next trigger
is input before the image for the previous trigger is
output.
