10-2-6 TRIGGER OUTPUT
The camera provides a range of trigger output signals to synchronize with an external instrument
and the camera becomes the master and the external instrument becomes the slave. There are
three different trigger output functions as follows. Also, it can output continuous High output
(High output fixed) or continuous Low output (Low output fixed).
These three different trigger output functions can be selected by software command, and
they are output from Timing out connector.
Note
•
Please refer to Figure 10-4 to Figure 10-11 about details of each trigger output functions.
10-2-6-1 Global exposure timing output
It shows the global exposure timing where all lines expose at the same time. There is a case
that one event is divided into two frames because the timing of the exposure in each line is
different for the rolling shutter. However, by using the Global exposure timing output the global
exposure becomes possible for the phenomenon that happens for this period. Global exposure
timing output shows the period where all lines expose at the same time.
Note
•
There is no output signal when the exposure time is less than the frame rate.
10-2-6-2 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.
Reference

Output signal
Read End
Camera outputs a pulse after certain delay, from the end of sensor readout. Also the
pulse width can be set.
Vsync
Camera outputs a pulse after certain delay, from the beginning of readout. Also the
pulse width can be set.
