31. Redundant Decoding
The Number of Redundant Decodes determines how many times the scanner must decode a bar code
and obtain the same value before it will transmit the data. For example, if the redundancy is set at three
times, the scanner will not transmit data until it has completed three consecutive, identical “good reads”.
In the case of a poor label which generates an intermediate “no decode” within a sequence of four scans
where three of the four have resulted in “good reads”, the scanner will transmit the data after the fourth
scan. In other words, a “no decode” does not restart the sequence.
