Output Data Editing
The Output Data Editing feature was removed from this barcode setup manual. It is
implemented to the Scanner Configuration Manager Software providing a user-friendly
interface for easier operation. Please download the latest program from Unitech’s web site at
http://www.ute.com. This chapter will mainly describe the concept and feature provided by this
data output feature. The function described here also can be replaced by the “Pre-defined
Labels” function. So if data-editing function is defined, “Pre-defined Labels” will be removed.
They cannot be defined at the same time.
General
The purpose of Data Edit is allowing you to define and modify a data record that comes from
decoding of a bar code. By using combination of formulas, you can perform the following
functions on the data received by the scanner:
A. Rearrange the output sequences.
B. Delete characters from the record.
C. Insert characters to the record, including function codes.
D. Duplicate characters in the record.
E. Insert time delay in the record
Formula
Formula is a structure that tells the scanner what and how to process the original data record
to produce the desired output. The wedge allows multiple Formulas, but the number of the
Formulas can be defined depends on the memory size allocated for Data Editing.
 Original Data Structure
The original data is the decoded data plus preamble and postamble. The original data structure
is as follow:
Preamble Decoded Data Postamble
 Formula Structure
A Formula consists of two parts: Qualifier and Modifier. Qualifier is used to verify if the data
record meets the conditions specified and Modifier is processed only if all conditions in
Qualifier are met.
 Execution Sequence
If several Formulas were defined, data editing will perform sequentially from the first Formula to
the last Formula. If a Formula is qualified and executed, the further formulas will be ignored. If
none of the Formulas is executed, the data record will be discarded and there will be no output
to the host.
