This is a signal input from the outside. Be sure to input both HD and VD signals in this case. Make the phase of the VD signal coincide with the falling edge of the HD signal during input operation.

Exposure time Te Te = Trigger width + 97 μs (XC-ES50/ES30, XC-EI50/EI30),

Te = Trigger width + 120 μs (XC-ES50CE/ES30CE, XC-EI50CE/EI30CE) (The trigger width should be between 2 μs and 1/4 s)

The normal operation state is engaged when the trigger high period exceeds 1/3 sec. After that the external trigger shutter operation is engaged when the trigger pulse goes “low”. 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. During the trigger inhibit period, an input trigger may be missed.

Be sure to input an external VD signal between 10 μs and 75 ms from the falling edge of a trigger pulse (as shown by 1 and 2 in the figure). For the input (except described above), the operation cannot be ensured. If the external VD signal is not input under the prescribed conditions, the normal operation is engaged several V after a change in input operation under the prescribed conditions.

When the external trigger shutter mode changes into the normal operation mode, one WEN signal is output.

Note : An image is superimposed when the next exposure ends before the previous image is output.
