may be set for any length, one or two discrete lengths, or lengths within a

specific range. If Code 39 Full ASCII is enabled, Length Within a Range or

Any Length are the preferred options. To set lengths via serial commands,

see Setting Code Lengths Via Serial Commands on page B-6.

NOTE

When setting lengths, single digit numbers must always be preceded by a

Two Discrete Lengths - This option limits decodes to only those Code 39

symbols containing either of two selected lengths. Lengths are selected from
