Scan Diagnostics
When Scan Diagnostics is turned on, the scanner sends a report instead of the
decoded message. Your terminal displays the diagnostic information first, then
the data from the scanned code.
Default = Off.
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
PDF417 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.
Reading distance varies, depending on x-dimension and row height of the
symbol. When you turn on the PDF Learn Mode, the IT3870’s light becomes
brighter when you are at the best distance for reading the PDF417 code.
