Data Editing

Prefix/Suffix Overview

When a bar code is scanned, additional information is sent to the host computer along with the bar

code data. This group of bar code data and additional, user-defined data is called a “message

string.” The selections in this section are used to build the user-defined data into the message

string.

Prefix and Suffix characters are data characters that can be sent before and after scanned data.

You can specify if they should be sent with all symbologies, or only with specific symbologies. The

following illustration shows the breakdown of a message string:

1-11 variable length 1-11 alpha numeric alpha numeric characters characters

Points to Keep In Mind

• It is not necessary to build a message string. The selections in this chapter are only used if

you wish to alter the default settings. Default prefix = None. Default suffix = None.

• A prefix or suffix may be added or cleared from one symbology or all symbologies.

• You can add any prefix or suffix from the ASCII Conversion Chart (Appendix B), plus Code I.D.

and AIM I.D.

• You can string together several entries for several symbologies at one time.

• Enter prefixes and suffixes in the order in which you want them to appear on the output.

To Add a Prefix or Suffix:

Step 1. Scan the Add Prefix or Add Suffix symbol

Step 2. Determine the 2 digit Hex value from the Symbology Chart (included in Appendix A) for

the symbology to which you want to apply the prefix or suffix. For example, for Code 128, Code ID

is “j” and Hex ID is “6A”.

Step 3. Scan the 2 hex digits from the Programming Chart (Appendix D) or scan 9, 9 for all

symbologies.

Step 4. Determine the hex value from the ASCII Conversion Chart (Appendix B), for the prefix or

suffix you wish to enter.

Step 5. Scan the 2 digit hex value from the Programming Chart (Appendix D)

Step 6. Repeat Steps 4 and 5 for every prefix or suffix character.

Step 7. To add the Code I.D., scan 5, C, 8, 0.

To add AIM I.D., scan 5, C, 8, 1.
