4.4 Trigger and Strobe

4.4.7

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 trigger mode
must be set to

Interface Trigger

or

I/O Trigger

.

4.4.8

Missed Trigger Counters

Missed Trigger Counter

If an external trigger (interface trigger or I/O trigger) is applied while

the camera is not ready to accept a new trigger, a counter (Missed Trigger Counter) is
incremented and the trigger is rejected. The value of the Missed Trigger Counter can be
read out from a camera register (

Counter.MissedTrigge

r) or from the status line (see

Section 4.10). When the Missed Trigger Counter reaches its maximal value it will not wrap
around. The user can reset the Missed Trigger Counter.

Missed Burst Trigger Counter

The missed burst trigger counter counts trigger pulses that were

ignored by the camera in the burst trigger mode because they occurred while the camera
was not ready to accept a new trigger. To avoid this, the Burst Period Time must be
incremented so that the minimal frame time for the current settings is not violated. The
value of the Missed Burst Trigger Counter can be read out from a camera register
(Counter.MissedBurstTrigger) or from the status line (see Section 4.10). When the Missed
Trigger Counter reaches its maximal value it will not wrap around. The user can reset the
Missed Burst Trigger Counter.

4.4.9

Strobe Output

The strobe output is an opto-isolated output located on the power supply connector that can
be used to trigger a strobe. 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 strobe output needs a separate power supply. Please see Section 6.1.3 and
Fig. 4.25 and Fig. 4.26 for more information.
