Code 128, continued
<GS> Substitution
A Code 128 FNC1 symbol character may appear in the first or second symbol
position to indicate compliance with certain industry standards. If the FNC1
appears in any other symbol position, the reader substitutes a <GS> character
(ASCII 1D hex) in the transmitted data. If <GS> Substitution is turned off, the
reader ignores all FNC1 characters except those that occur in the first or second
symbol position.
Default = On.
ISBT 128
The International Society of Blood Transfusion (ISBT) ratified a new standard in
1994 for communicating critical blood information in a uniform manner. The
ISBT
128 Application Specification describes 1) the critical data elements for labeling
blood products, 2) the current recommendation to use Code 128 due to its high
degree of security and its space-efficient design, 3) a variation of Code 128 that
supports concatenation of neighboring symbols, and 4) the standard layout for
bar codes on a blood product label.
