Programming

• UPC A and E Preamble

Three options are given for the lead-in characters of decoded UPC-A or
UPC-E symbols transmitted to the host device. Select one preamble for UPC-A
decodes and one for UPC-E decodes. These lead-in characters are considered
part of the symbol itself. The three options are:

a system character only

the country code and system character

no preamble

The system character is the digit printed to the extreme left of a UPC symbol.
The country code for UPC is always zero, and it cannot be transmitted without
the system character.

• Prefix/Suffix Values

A prefix/suffix may be appended to scan data for use in data editing. These
values are set by scanning a four digit number (i.e., four bar codes) that
correspond to keycodes for various terminals. An ASCII table begins on
