*1 This is a signal input from outside. The continuous VD frequency is one field. Make sure you input HD and VD at the same time.
*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. 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.
Note
An image is not output correctly when the next trigger is input before the image for the previous trigger is output.
