Count direction of the code position CP
Explanation
The CLX can scan and decode several bar codes with each read. In doing so, it determines
the specific local reading diagnosis data for each bar code the position (CP value) of the cen-
ter of the bar code within the scan.
shows the count direction of the code position. The count direction of the code po-
sition is marked by a cross in the reading window.
By determining this data, the device can separate identical bar codes (code type, code
length, and data content identical) and assign the bar code data in the reading result to its
position on the object.
Tip
In the default setting, the CLX does not output the "CP" value in the reading result on the
host interface. If this is required to evaluate the result in the host, the values can be included
in the separator of the output string using the "CLV-Setup" program.
