Enable Bi-directional Redundancy for added security to linear code type security levels. When enabled, a bar code 
must be successfully scanned in both directions (forward and reverse) before reporting a good decode.

The Code 39 and Codabar symbologies have an intercharacter gap that is typically quite small. Due to various bar 
code printing technologies, this gap can grow larger than the maximum size allowed, preventing decode. If this 
occurs, select Large Intercharacter Gaps to tolerate these out-of-specification bar codes.
