*Scan “PP” to end preamble setting.

*Scan “OO” to start postamble setting.

*Scan ‘ETX’ from Full ASCII Table.

*Scan “OO” to end postamble setting.

*Scan “Exit”.

6.1.5 Predefined Labels

The scanner provides three special labels encoded as “/FY”, “/FZ” and “/F-” in Code 39 format. The output from these labels can be defined through the setup menu. The definition of the labels share the same space with “Edit Formula definition”(See “Output Data Editing”), so you can only use either one of the function.
