*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 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 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.
*5 Video out 2 is output only in the 2I mode.
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.
