Code length:
The code length is transmitted as 2 digits, representing the decimal number of data
characters transmitted, excluding prefix and suffix characters. For 2D bar codes the
code length is transmitted as 6 digits. It is also possible to send for both 1D and 2D
codes the length as 6 digits. These direct input characters count as 1 entry of the 4
permissible entries for a prefix or suffix.
Example:
If you want to configure the prefix <code identifier>:<code length>: scan the
following labels:
<SET>
<Set prefix all>
<Code identification>
<:>
<Code length>
<:>
<END>
If you want to use the code identifiers, but need another code identifier for Code 39,
you scan the following labels:
<SET>
<Set prefix all>
<Code identification>
<:>
<Set prefix Code 39>
<$>
<:>
<END>
