8.6.5 Optimizing reading performance
Optimize the reading performance of the code reader using the following settings in the webConfig tool:
•
Decoding table
Limiting of the code types being searched for and the number of digits
The adjustment options can be found in the webConfig tool: Configuration > Decoder > Code types
•
Exposure time
A short exposure time enables high object speeds. Because the image brightness is thereby
reduced, it may be necessary to adjust the signal gain. Image noise increases as a result, however.
The adjustment options can be found in the webConfig tool: Configuration > Image acquisition
•
Region of interest
Define a region of interest (ROI) to restrict coding to a single part of the image. If no region of interest
is defined, the complete image is defined as the region of interest.
The adjustment options can be found in the webConfig tool: Configuration > Decoder > Region of
interest
•
Max. decoding time
Define the maximum decoding time to limit the execution time of the code search algorithm.
The adjustment options can be found in the webConfig tool: Configuration > Decoder > Properties
•
Camera operating mode
Select the
Single trigger mode
camera operating mode for fast complete decoding.
The adjustment options can be found in the webConfig tool: Configuration > Control > Camera oper
-
ating mode
•
Maximum number of codes
If the maximum number of codes to be expected in an image (ROI) is small and known, the code
search will be accelerated.
Define the maximum number of codes that can be decoded in a test program. If the defined number
of codes has been decoded, the code search algorithm is interrupted.
The adjustment options can be found in the webConfig tool: Configuration > Decoder > Extended
•
Image transfer
Deactivation of image transfer in process mode increases the decoding rate.
Adjustment options can be found in the webConfig tool: Configuration > Device > Image transfer
8.6.6 Transfer configuration data
Transferring configuration data with the webConfig tool
With the webConfig tool, you can store complete device configurations on data carriers and transfer them
from these to the device: Maintenance > Backup/Restore
This storage of configuration data is especially useful if you want to store basic configurations which will
require only minor changes.
