decoder beeps twice and ignores the programming instructions in

Guidelines for Creating Batch Bar Codes
Keep the following in mind when creating bar codes for batch
programming:
•
Create your programming bar codes using the standard Code 39
character set,
not
the full ASCII character set. (You must read the
bar codes in full ASCII Code 39 mode, however.)
•
The first and last character of each bar code must be an asterisk (*),
the start and stop character for Code 39. (Most label-printing soft-
ware programs automatically place the asterisks in Code 39 bar
codes.)
•
The first asterisk of each bar code must be followed immediately by
the characters $+$-. This lets the decoder know that it is reading
programming information rather than data.
•
Each bar code must end with EE and the final asterisk.
•
String data must appear in a programming bar code after the I.D.
number for the code parameter. Use two slashes (//) to terminate the
string. (Parameters that accept string data include preambles and
postambles.)
•
You must enter control or “action” characters (for example, tabs, line
feeds, or function keys) by encoding their Code 39 equivalents (see
Full Keyboard Support on page 81
). For example, to enter a horizontal tab,
you would include the character pair $I in the bar code.
NOTE
Programming Bar Codes on page 46
, contains batch bar codes for most of the set-
tings you will need. To make your own batch bar codes, see the section titled,
Programming Options on page 34
, for parameter I.D. numbers and acceptable set-
tings.
