1.9 READ REDUNDANCY (1D)
Select the level of reading redundancy. For example,
If "No Redundancy" is selected, one successful decoding will make the reading valid
and induce the "READER Event".
If "Two Times" is selected, it will take a total of three consecutive successful decoding
of the same barcode to make the reading valid. The higher the reading redundancy is
(that is, the more reading times the user selects), the slower the reading speed gets.
It is obvious that the more redundancy selected, the higher the reading precision is, and
thus, the slower the reading speed becomes. It will have to compromise between reading
precision and decoding speed.
