4.4.6 Software Trigger
The software trigger enables to emulate an external trigger pulse by the camera software
through the serial data interface. It works with both burst mode enabled and disabled. As
soon as it is performed via the camera software, it will start the image acquisition(s),
depending on the usage of the burst mode and the burst configuration. The software trigger is
not working FreeRunning mode.
4.4.7 Strobe Output
The strobe unit is implemented in the form of two interfaces:
•
RS422 compatible interface
•
Opto-isolated interface.
Each interface has 3 output channels OUT[0..2]. Channel OUT0 is dedicated for very fast strobes
and is a FPGA output signal. Channel OUT1 and OUT2 are used for the slow strobe outputs and
are connected with DSP output signals. Fig. 4.33 shows the different kinds of interfaces in a
simplified manner. The pinout of the interface connectors are given in Appendix Appendix A.
For further hardware details see Section 5. The strobe output can be used both in free-running
and in trigger mode. There is a programmable delay available to adjust the strobe pulse to
your application.
The opto isolated strobe outputs OPTO_OUT[0..2] need a separate power supply.
Please see Appendix Appendix A for more information.
