1.9 READ REDUNDANCY (1D)
Select the level of reading security. 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 security is
(that is, the more redundancy the user selects), the slower the reading speed gets.
It is obvious that the more redundancy you select, the higher the reading security is, and
thus, the slower the reading speed becomes. You will have to compromise between
reading security and decoding speed.
