Code 128
Purpose: Enables/disables decoding of Code 128 symbology. Code 128 is a very high
density alphanumeric symbology. It is a variable length, continuous code
employing multiple element widths. Code 128 symbology can be configured to
Standard or UCC/EAN, which affects how function code 1 characters are
decoded. Function code 1 characters are decoded as follows:
•
If Code 128 is configured to Standard, the reader will not decode function
code 1 characters in bar code labels.
• If Code 128 is configured to UCC/EAN, the reader will decode the bar code
label as standard Code 128 unless the first two characters are a start
character and a function code 1. If the first two characters are a start
character and a function code 1:
1. The first two characters are not transmitted.
2. The three symbology ID characters, ]C1, are transmitted.
3. The remaining Code 128 characters are decoded as standard
Code 128.
4. Any subsequent function code 1 characters are translated to the ASCII
GS character as a separator for variable length fields.
