3.6.1 Synchronization input (SYNC-IN)
If a third party device is connected to the synchronization input SYNC-IN then depending on
the setting of the configuration window from the application software the measurement will
start/stop or “frame by frame” synchronized by a signal from the third party device. Input is
protected against faulty polarisation and pin 1 is set to +5V ("1") by an internal pull-up- re-
sistor 2.7 k
. If this input is set to 0 V ("0") i.e. by a switch or break contact than the SYNC-
IN is triggered.
