BAR CODE INFORMATION

Since you may use any of the four start/stop characters on either end of

the symbol, there are 16 possible combinations. These combinations can

identify the product type or other information.

PLESSEY AND MSI1

PLESSEY code supports numerals 0-9, plus six additional characters

(typically A-F). PLESSEY uses a check digit, but the check digit may be

calculated several different ways. To allow the user some flexibility the

printer does not calculate or print the check digit. You must calculate

and enter the check digit manually, according to the requirements of

your bar code system.

MSI is a modified PLESSEY code that uses two check digits. The

printer automatically calculates and adds the check digits. The check

digits are not printed in the bar code subtext.

MSI1 is another modified PLESSEY code that uses one check digit.

Again, the printer will automatically calculate and add the check digit.

The check digits are not printed in the bar code subtext.

MAXICODE

MAXICODE is a fixed-size, two-dimensional bar code symbology

consisting of a matrix of hexagonal elements arranged around a bull’s-

eye "finder pattern." MaxiCode uses five code sets (designated A

through E) to encode all 256 characters of the extended ASCII character

set. Cognitive’s implementation of MaxiCode only supports code set A at

present. This code set can represent the uppercase characters A - Z,

numerals 0 - 9, most common punctuation marks, and a few special

symbols.

PDF417

PDF417 (an abbreviation for Portable Data File 417), originally

developed by Symbol Technologies, Inc., is a two-dimensional stacked

bar code symbology. It is a highly compact medium for encoding any

data representable by the 256 characters of the International Character

Set.

The codeword is the basic unit of a PDF417 bar code. All data encoded

using PDF417 is first converted to a decimal value between 0 and 928

inclusive, since there are 928 discrete symbols that can be represented
