11.2 Random trigger shutter
Images can be taken and imported at arbitrary timing by inputting an external trigger signal in a random trigger
shutter mode.
・
External trigger signals can be input from either the camera link I/F CC1 or the DC IN connector. However,
signals cannot be input at the same time. Fix an unused input to Low.
・
It starts exposure at a rising trigger edge when the polarity is set to positive polarity while it starts exposure at a
negative-going trigger edge when the polarity is set to negative polarity.
・
Random trigger shutter operates in either the fixed mode and the pulse width mode and has different ways to
determine the exposure time depending on the mode.
・
Film cannot be exposed during reading images using the random trigger shutter. If inputting triggers is to be
continued, input them after finishing image output of the camera.
1) Fixed mode
・
The exposure time is determined by the set value of the shutter speed.
