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 codes.
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.
