The setting Counter_ResetCounterMode=Continuous resets the counters on every occurrence of an
active edge of the reset source without the requirement to arm the device first. This setting is
suited if the reset source signal is different than the camera trigger.
The active edge of the reset input can be set by the property Counter_ResetCounterSourceInvert.
If set to True, then the rising edge is the active edge, else the falling edge.
Counter reset by an external signal is important if you would like to synchronize
multiple cameras. One signal is applied to all cameras which resets the coun-
ters simultaneously. The timestamps of all cameras are then theoretically syn-
chronous with each other. In practice every camera runs on its own clock source
which has a precision of +/- 30 ppm and therefore the values of the timestamp
(real time counter) of the cameras may diverge with time. If this is an issue, then
the counters could be reset periodically by the external signal.
The counter reset by an external signal feature is not available on all camera
revisions, see Appendix B for a list of available features.
Reset of Individual Counters (ResetCounter_Dual)
If the property ResetCounter_Dual is set to False or if this property is not available, then the
ResetCounter settings apply to the image counter and to the real time counter together.
If ResetCounter_Dual is set to True then CounterReset can be set separately for the image
counter and for the real time counter. In this case the settings without 'RTC' are applied to the
image counter and the settings with 'RTC' in its name are applied to the real time counter.
The ResetCounter_Dual feature is not be available on all camera revisions, see
Appendix B for a list of available features.
