Functions
This chapter describes the functions of the code reader:
• Camera operating modes (see chapter 4.1 "Camera operating modes")
• Reference code comparison (see chapter 4.2 "Reference code comparison")
• Code quality (see chapter 4.3 "Code quality")
• webConfig tool (see chapter 4.4 "Leuze webConfig tool")
4.1
Camera operating modes
The camera operating mode defines how the code reader starts a read process and decodes the codes if a
code is located in the read field.
4.1.1
Single trigger mode
In the "Single trigger mode" camera operating mode, the code reader captures
one
image and attempts to
decode it. Under uniform conditions, this camera operating mode makes fast decoding possible.
4.1.2
Reading gate control
The "Reading gate control" camera operating mode is activated upon shipment from the factory. The read-
ing gate control opens a time window for the read process in the code reader – the reading gate. In this
time window, the code reader can capture and decode one or more codes.
4.1.3
Burst mode
In the "Burst mode" camera operating mode, the code reader captures
multiple
images in quick succession
after activation by a trigger signal.
• Decoding occurs following image capture, thereby allowing the codes to be detected more quickly.
• As soon as the decoding result corresponds to the settings, the decoding stops the capture of the re-
maining images.
