Code 39 Start/Stop Characters
Start/Stop characters identify the leading and trailing ends of the bar code. 
You may either transmit, or not transmit Start/Stop characters.  
Default =  
Don’t Transmit.
Code 39 Check Character
No Check Character indicates that the engine reads and transmits bar 
code data with or without a check character.
When Check Character is set to Validate, but Don’t Transmit, the unit 
only reads Code 39 bar codes printed with a check character, but will not 
transmit the check character with the scanned data.  
When Check Character is set to Validate and Transmit, the engine only 
reads Code 39 bar codes printed with a check character, and will transmit 
this character at the end of the scanned data.  
Default = No Check Character.
Code 39 Redundancy
If you are encountering errors when reading Code 39 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 Code
