Trigger Mode - Sony XCL-5005CR Technical Manual

4.2.4.

Trigger mode

This mode is for starting exposure by synchronization
with the external trigger input (12-pin or 26-pin
connector) and then outputting the individual video
signals of all pixels after the time that was set for the
shutter elapses. There is the edge detection mode for
detecting the rise edge of the external trigger signal and
the width detection mode for detecting the effective
period of the trigger. The period of the external trigger
signal cannot be set shorter than the shutter speed.
Furthermore, if the shutter is set to OFF, the shutter
speed is automatically set to 1/15 s.
