*1 This is a signal input from outside.
*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 The internal VD signals are output as long as there is no external input and the HD/VD signal input/output switch on the rear panel is set to INT.
*5 An image is output when an internal 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 internal VD falling edge (T in the figure) is under 10 ms, it is not defined whether the image is output for the internal VD falling edge or the image is output for the next internal VD falling edge. (1 in the figure shows that the image is output for the next internal VD). In this case, see WEN since the image and WEN make up a pair.
(The internal VD falling edge and the beginning of the equivalent pause in the V period of the SYNC have the same phase.)
Note
An image is not output correctly when the next trigger is input before the image for the previous trigger is output.
