When mode PULSE SYNC is used LED bright-
ness is set to 150%.
The shutter output of industrial high speed cam-
eras can be used as trigger signal for the
PULSE SYNC.
By utilizing pulsed light optimal lighting condi-
tions for industrial cameras can be accom-
plished without being too bright or disturbing for
the human eyesight.
In order to use PULSE SYNC the
