Strip Leading/Trailing Control
This group of controls determines what data is removed from the barcode before the data is
buffered for the application. If all values are set, Code ID takes precedence over Leading and
Trailing; Barcode Data stripping is performed last. Stripping occurs before the Prefix and Suffix
are added, so does not affect them.
See Also: Barcode Processing Overview earlier in this chapter.
Figure 4-6 Strip Leading / Trailing and Barcode Data
If the total number being stripped is greater than the number of characters in the barcode data, it
becomes a zero byte data string. If, in addition, Strip Code ID is enabled, and no prefix or suffix is
configured, the processing will return a zero-byte data packet, which will be rejected.
The operation of each type of stripping is defined below:
Leading This strips the number of characters specified from the beginning of the barcode data
(not including Code ID). The data is stripped unconditionally. This is disabled by
default.
Trailing This strips the number of characters specified from the end of the barcode data (not
including Code ID). The data is stripped unconditionally. This is disabled by default.
Code ID Strips the Code ID based on the type code id specified in the Enable Code ID field in
the Barcode tab. Programmed custom identifiers are always checked (in the order they
are entered) and stripped, regardless of Enable Code ID setting. By default, Code ID
stripping is enabled for all symbologies (meaning code IDs will be stripped, unless
specifically configured otherwise).
