The length of a code refers to the number of characters (i.e., human readable characters), including check digit(s) 
the code contains. Lengths for Codabar may be set for any length, one or two discrete lengths, or lengths within a 
specific range. 

One Discrete Length - This option allows the scanner to decode only those Codabar symbols containing a 
selected length. Lengths are selected from the numeric bar codes in 

. For 

example, to decode only Codabar symbols with 14 characters, scan Codabar - One Discrete Length, then scan 1 
followed by 4. In case of an error, or to change the selection, scan Cancel on 

.

Two Discrete Lengths - This option allows the scanner to decode only those Codabar symbols containing 
either of two selected lengths. Lengths are selected from the numeric bar codes in 

. For example, to decode only those Codabar symbols containing either 2 or 14 characters, select Codabar 

- Two Discrete Lengths, then scan 0, 2, 1, and then 4. In case of an error, or to change the selection, scan 
Cancel on 

.

Length Within Range - This option allows the scanner to decode a Codabar symbol with a specific length 
range. The length range is selected from numeric bar codes in 

Appendix D, Numeric Bar Codes. 

For example, 

to decode Codabar symbols containing between 4 and 12 characters, first scan Codabar - Length Within 
Range. Then scan 0, 4, 1, and 2 (insert a leading zero for single digit numbers). In case of an error, or to change 
the selection, scan Cancel on 

.

Any Length - This option allows the scanner to decode Codabar symbols containing any number of characters 
within the scanner capability.
