PDF417, continued
The following list shows the information that appears for the PDF417 symbology.
Note:
The higher the percentage of unused error correction (UEC), the easier it
should be to read each code.
PDF 417:
x rows, x cols, xx data & xx chks (ECL = x), UEC = xxx%
Rows = Number of rows
Cols = Number of columns
Data = Number of data words
Chks = Number of check words
ECL = Error Correction Level
UEC = Unused Error Correction
PDF Learn Mode
This setting tells the scanner to brighten the LED’s when you have an optimal
distance between the scanner and the PDF417 code you are attempting to read.
Because some PDF417 codes are more compact than others, the reading
distance varies from code to code. When you turn on the PDF Learn Mode, the
3800/3900’s light becomes very bright when you are at the best distance for
reading the PDF417 code.
Default = Off.
