Chapter 7 Output Data Editing
The function described here can be replaced by the
7.1. 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
7.2. 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.
7.2.1. 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
7.2.2. Formula Structure:
A Formula consists of two parts: Qualifier and Modifier (See Figure 7.1). 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.
7.2.3. 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.
