Code Lengths

The length of a code refers to the number of characters (human

readable characters) the code contains. You can set the code length

for certain one-dimensional code types (Code 39, Codabar,

Interleaved 2 of 5) to any length, one or two disrete lengths, or

lengths within a specific range. You cannot set a discrete length for

Code 128.

Select this option to decode a one-dimensional code containing any

number of characters. For example, to scan a Codabar symbol

containing any number of characters, scan Codabar Any Length.

Select this option to decode a one-dimensional code containing a

length within a specified range. For example, to decode Code 39

codes containing between 4 and 12 characters, scan the Code 39

Length Within Range code. Then scan, 0, 4, 1, 2. Single digit

numbers must be preceded with a zero.

Select this option to decode only one-dimensional codes containing a

selected length. For example, to decode Codabar codes containing

14 characters, scan Codabar – One Discrete Length. Then scan 1

and 4.

Select this option to decode only one-dimensional codes containing

two selected lengths. For example, to decode Interleaved 2 of 5

codes containing 2 or 14 characters, scan Interleaved 2 of 5 – Two

Discrete Lengths. Then scan 0, 2, 1, 4. Single digit numbers must

be preceded with a zero.
