Explanation of trigger signal edge and triggers for edge/level:
Trigger signal edge: The sensor responds to edges, i.e., signal changes
(rising/falling edge) that are triggered by a photoelectric sensor.

Triggers for edge/level: The sensor responds to a pending level, which means it
initiates synchronous trigger cycles as long as the signal is pending, i.e., image
capture, decoding, image capture, decoding, image capture, decoding.
Automatic sensor start
If "Triggers for edge/level" mode is activated, it is possible for the sensor to start
running automatically and trigger, if the trigger input wiring is connected
permanently to High (or Low).
Procedure: Triggers for level active and single trigger mode active -> Trigger as
long as level is High.

Image mode: How the code is to be read. If mirrored is selected, then the
reader expects a mirrored code (read via a deviation mirror).
Select parameter file: A backup file can be loaded into the sensor. Use
the Browse...button to select the file and then load it into the sensor with
the Send button.
Download parameter file: The settings that you have made can be saved
in a backup file.
Set default decoder parameters: Resets all values to their default values.
