Scanner Parameters
Code 128
Code 128 is a smaller symbology useful in applications with limited space and high-security
requirements.
A very dense alphanumeric symbology. It encodes all 128 ASCII characters, it is continuous,
has variable length, and uses multiple element widths measured edge to edge.
Fixed Symbol Length Status
When enabled, the scanner will check the symbol length against the symbol length field. If
disabled, any length will be considered a valid symbol.
Fixed Symbol Length
Fixed Symbol Length helps prevent truncations and increases data integrity by ensuring
that only one symbol length will be accepted.
This specifies the exact number of characters that the scanner will recognize (this does not
include start, stop, and check character characters). The scanner ignores any symbol not
having the specified length.
