Programmable timing output

By using the programmable timing output, synchronizing external devices is simple. A system
that needs simple timing signal does not require a delay unit or pulse generator. It is possible to
program and output a pulse that has an optional pulse width and an optional delay time to the
end of readout timing or Vsync. The setting range for delay time is 0 µs to 10 s, and the setting
range for pulse width is 10 µs to 10 s.
The relation between the parameter which can be set with each reference signal, and an output
signal becomes below.

9-6-3-3 Trigger ready output
The trigger ready output is useful to make the frame intervals as short as possible in external
trigger mode. For example, when the camera is working in the edge trigger mode, the next frame
can start after the previous frame exposure is done. Thus, the camera cannot accept a trigger for
the next frame during the exposure period. To reduce useless time to be as short as possible, it
is necessary to know the period when the camera can accept a trigger for the next frame. The
trigger ready output shows the trigger ready period when the camera can accept an external
trigger in the external trigger mode.
Camera outputs a pulse after certain delay, from the end of sensor readout.
Also the pulse width can be set.
Camera outputs a pulse after certain delay, from the beginning of readout. Also
the pulse width can be set.
