Honeywell N431X User Manual

6 - 11

No Check Digit indicates that the engine reads and transmits bar code 
data with or without a check digit.

When Check Digit is set to Validate, but Don’t Transmit, the unit only 
reads Interleaved 2 of 5 bar codes printed with a check digit, but will not 
transmit the check digit with the scanned data.  

When Check Digit is set to Validate and Transmit, the engine only reads 
Interleaved 2 of 5 bar codes printed with a check digit, and will transmit this 
digit at the end of the scanned data.  

Default = No Check Digit.

If you are encountering errors when reading Interleaved 2 of 5 bar codes, 
you may want to adjust the redundancy count.  Redundancy adjusts the 
number of times a bar code is decoded before transmission, which may 
reduce the number of errors.  Note that the higher the redundancy count, 
the longer it will take to decode the bar code.  To adjust the redundancy, 
scan the Interleaved 2 of 5 Redundancy bar code below, then scan a 
redundancy count between 0 and 10 on the 

back cover of this manual.  Then scan the 

 bar code.  

Default = 0.
