Note: Do not create bar codes with the FNC 3 character unless instructed to do so by Technical Support. These bar codes
are used to control and configure the decoder.
FNC 4 provides access to the extended ASCII mode. Data encoded in code set A and B have their values increased by 128 from
the normal ASCII values. For example, code set B value 65 normally encodes an "a" or ASCII data value 97; therefore, using FNC
4, it would encode an extended ASCII data value 225 or 97+128. Code subset C's numeric characters (ASCII values 48 - 57) are
not changed by using FNC 4.
A single FNC 4 toggles in or out of extended ASCII mode for the next data character. Two consecutive FNC 4 symbol characters
toggle the extended ASCII mode state for all succeeding data characters until another double FNC 4 or the end of the symbol. (A
single FNC 4 changes back to normal mode for a single character.)

Interleaved 2 of 5 Characteristics
Interleaved 2 of 5 (also called I 2/5 or ITF) is a bar code symbology with a numeric character set and unique start and stop
patterns. Interleaved 2 of 5 symbols always contain an even number of digits. In the symbol, two characters are paired together
using bars to represent the first character and spaces to represent the second. Each character has two wide and three narrow
elements. To enhance bar code integrity a check digit and Bearer Bars can be present.
