Image acquisition
The optical readers detect the object characteristics required for the task using digital image
acquisition.
Following image acquisition, the image is analyzed by a powerful digital signal processor.
Depending on the application, multilevel complex algorithms are used during the analysis:
● To find and decode the codes contained in the image.
● To verify codes.
The results of the evaluation are transferred to an automation system connected via the
communications interfaces.
The user is supported in the use of the optical reader by a variety of feedback messages:
● Live image display
● Auto-detection for code type recognition
● Result and quality preview
● Display of diagnostic images
● Warning and error messages
● 3-language online help in the optical reader
Web Based Management (WBM)
The WBM is based on Web server technology. This means that only a computer with an
Internet browser connected with an optical reader via Ethernet is necessary. The optical
reader is then called using its IP address. The display of the WBM appears in the display
window of the Internet browser. Display via Ethernet allows convenient setting and control of
all parameters of the optical reader. Operator control of the optical readers is supported by
context-sensitive online help.
If automatic adjustment does not lead to an optimum result due to special conditions, you
can use the WBM to readjust individual parameters of the optical reader manually. You can
save 15 different settings in the optical reader.
Depending on the task, up to 12 processing steps can be set as a sequence in one program.
The following processing steps are available:
● Decoder step for reading 1D/2D codes
You can store up to 15 different programs on the reader.
The settings for communication with other devices must be made in the WBM.
