TRIGGER OUTPUT
9-8
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.
- Global exposure timing output
- Programmable timing output
- Trigger ready output
Also, it can output continuous High output (High output fixed) or continuous Low output (Low
output fixed).
These trigger output functions can be selected by software command, and they are output from
Timing out connector. And the polarity can be changed by software command.
9-8-1 GLOBAL EXPOSURE TIMING OUTPUT
Global exposure timing output shows the period of all pixels exposing.
•
For more detail, please refer to the timing charts of Figure 9-1 to 9-8.
9-8-2 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 nor pulse generator. It is possible to
program and output a pulse that has an optional pulse width and an optional delay time to the
exposure start timing of the camera by command.
The setting range for delay time is 0 µs to 10 s, the setting range for pulse width is 1 µs to 10 s, and
the minimum setting step is respectably 1 µs.
