Redundancy (1D code common)
9.2.3
When redundancy is enabled, a 1D code has to be scanned and decoded multiple times and the
results must be the same before it considered correctly decoded. The redundancy count is the number
of times that the code has to be scanned in addition to the first scan. Selecting a higher redundancy
count reduces the probability of reading errors, but it makes the output response slower. With high
quality printed codes, the default setting is enough to ensure the reliability.

* This setting only affects the reading of 1D barcodes. 2D codes are not affected by this redundancy setting
Add-on waiting time
9.2.4
The scanner search valid UPC/EAN add-on code within the selected time. If effective add-on code is
found, scanner sends data immediately. If there is nothing after the code, scanner sends data without
add-on. If there is something after the code, but not valid add-on code, reader ignores the code.
“Supported code”
• UPC 2 digits / 5 digits add-on and GS1 composition symbol
• EAN/JAN 2digits / 5 digits add-on and GS1 composition symbol.
