Scanner Redundancy
Purpose: Defines the number of scans (voting) the scanner takes of the same label that
must be decoded correctly for a good read of the label. Voting allows the
JANUS 2050 to decode the same bar code label multiple times during a single-
trigger event, and to compare the decoded information a specific number of
times before signaling a good read. Setting the redundancy configuration to low
allows the JANUS 2050 to accept the first good read, which speeds up
performance. This setting is recommended for good quality bar code labels.
When configured to normal, the JANUS 2050 decodes the bar code label a
minimum number of times in each trigger event. When configured to high, the
JANUS 2050 scans and decodes the bar code label a maximum number of times
in each trigger event. The specific number of comparisons depends on each bar
code symbology.
For example, when you are scanning Code 39 labels and voting is configured to
moderate, two successive matching decodes in a single-trigger event are
required. When voting is configured to high, three successive matching decodes
in a single-trigger event are required.
Setting the redundancy configuration to high is important when scanning poor
quality labels that may cause substitution errors.
