*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.
*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.
