Data Capture
Overview
Laser scanning
Things to be considered for scanning
CW30 provides two kinds of data capture modes:
Laser decoding
Image decoding
The barcode scanning features of CW30 are as follows:
Recognizing various linear barcodes such as Code39, Codel128, or 1-dimension barcodes, etc.
User-de¿ned setting mode customizable for users
’
working environments.
Generally, scanning is a very simple task composed of leveling, scanning, and decoding. Therefore, a user can
be familiar with the process after a few trials. However, the followings should be noted beforehand to optimize the
scanning performance:
Distance
All scanning devices have their optimal recognition range (minimum or maximum distance from a barcode).
This range may differ in barcode sizes or in the type of scanning devices. If a scanning task is performed within
the range, scanning will be fast and reliable, but if the task is performed within too close distance or too far
distance, the success rate will decrease.
When scanning, move CW30 forward and backward in order to ¿nd an optimal operation range.
Angle
Scanning at too tilted angle is more likely to fail in recognition.
The bigger a barcode is, the greater distance between the barcode and CW30 should be.
The shorter the distance between barcodes, the closer the use of CW30.
To perform data capture mode, a scanning application must be installed in CW30.
