Scans Required 

This parameter sets the number of scans required to read an Interleaved 2 of 5 bar code. 

Increasing the number of scans can improve reading nominal bar codes. There are four 

settings: 1 scan, 2 scans, 3 scans, and 4 scans. The default is 2 scans. Set this parameter by 

scanning the appropriate Hex tag (Hex 1 to Hex 4). 

Overlap Characters 

This parameter sets the minimum number of characters which each segment must contain 

when tag stitching is done. There are four settings: 1 overlap character (Hex 1) (default), 2 

overlap characters (Hex 2), 3 overlap characters (Hex 3), and 4 overlap characters  

(Hex 4). Set this parameter by scanning the appropriate Hex tag (Hex 1 to Hex 4). 

Minimum Segment Size 

This parameter sets the minimum number of characters which each segment must contain 

when tag stitching is done. Set this parameter by scanning the appropriate Hex tag (Hex 2 to 

Hex 9). The default is  

Hex 3.
