Conventions for Bar Codes
You can scan the bar codes listed in this manual to enter data or perform a command.
The bar code labels in this manual are printed in the Code 39 symbology. Each bar code
includes the name and human-readable interpretation. For example:
*$+*
Change Configuration
*$+*
Name
Bar code (Code 39)
Human-readable
interpretation
242XU.146
The asterisks (*) at the beginning and end of the human-readable interpretation are the
start and stop codes for a Code 39 bar code label. If you are using a bar code printing
utility, it may automatically supply the asterisks as the start and stop code, so that you
only need to type the actual text of the command. You can also create and print
configuration labels and reader command labels in Code 93, which has its own start and
stop codes.
