Scanner Redundancy
Purpose: Defines the number of scans (voting) the scanner takes of the same label that must decode
correctly for a good read of the label. Voting requires the terminal to decode the same bar
code multiple times during a single scanner event, and to compare the decoded
information a specific number of times before signaling a good read. There are three
options:
None
Allows the terminal to accept the first good read, which speeds up terminal
performance. This setting is recommended when scanning good quality bar code labels.
Normal
The terminal decodes the bar code a minimum number of times in each scanner
event. The number of comparisons that are made depends on each bar code symbology.
High
The terminal scans and decodes the bar code a maximum number of times in each
scanner event. The specific number of comparisons depends on each bar code symbology.
The high setting is recommended when scanning poor quality labels that may cause
substitution errors.
For example, when you scan Code 39 labels and the scanner redundancy is set to normal,
two successive matching decodes in a single scanner event are required. When scanner
redundancy is set to high, three successive matching decodes in a single scanner event are
required.
