Wasp Bar Code WLS 8400 FZ 用户手册

8-27

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 Code 39 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.

When setting lengths for different bar code types by scanning single 
digit numbers, single digit numbers must always be preceded by a 
leading zero.

One Discrete Length - This option allows the scanner to decode only those Code 39 
symbols containing a selected length. Lengths are selected from the numeric bar codes 
beginning on page 

 in 

. For example, to decode only 

Code 39 symbols with 14 characters, scan Code 39 - One Discrete Length, then scan 1 
followed by 4. In case of an error, or to change the selection, scan Cancel on page 

Two Discrete Lengths - This option allows the scanner to decode only those Code 39 
symbols containing either of two selected lengths. Lengths are selected from the numeric 
bar codes beginning on page 

. For example, to 

decode only those Code 39 symbols containing either 2 or 14 characters, select Code 39 - 
Two Discrete Lengths, then scan 0, 2, 1, and then 4. In case of an error, or to change 
the selection, scan Cancel on page
