YMBOLOGY
Symbology-specific label identifiers comprise one or two ASCII characters
that can precede or follow bar code label data as it is transmitted to the
host. The host uses these characters as a means of distinguishing between
symbologies.
Industry standards have been established for symbology-specific label
identifiers, and are listed in the table below. Most scanners will have
factory default identifiers preset to these standards.
UPC-A ------------------------ 'A'
UPC-E ------------------------ 'E'
EAN-8 ----------------------- 'FF'
EAN-13 ----------------------- 'F'
UPC-A (2 add-on) --------- 'A'
UPC-A (5 Add-on) --------- 'A'
UPC-A (8 Add-on) ---------- 'A'
UPC-E (2 add-on) --------- 'E'
UPC-E (5 Add-on) --------- 'E'
UPC-E (8 Add-on) ---------- 'E'
EAN-8 (2 add-on) --------- 'FF'

To set symbology-specific label identifiers:
1. Look at the ASCII chart on the inside back cover and identify
the ASCII character(s) and the corresponding Hex Code(s) for
the ASCII characters you will use as identifiers. You will also
need to determine whether the character(s) will need to be
sent as a prefix or a suffix.
For example: You need to change the label identifier prefix
for UPC-A to 'A1'.
2. Scan the SET label below.
3. Scan either the TRANSMIT LABEL I.D. AS PREFIX or TRANS-
MIT LABEL I.D. AS SUFFIX, depending on your requirements.
For our example, the 'transmit as prefix' label would be
scanned.
