Code 128, continued
ISBT 128 Concatenation
In 1994 the International Society of Blood Transfusion (ISBT) ratified a standard
for communicating critical blood information in a uniform manner. The use of
ISBT formats requires a paid license. 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. Use the bar codes below to turn concatenation on or off.
Default =Off.

Code 128 Code Page
Code pages define the mapping of character codes to characters. If the data
received does not display with the proper characters, it may be because the bar
code being scanned was created using a code page that is different from the one
the host program is expecting. If this is the case, scan the bar code below, select
the code page with which the bar codes were created from the chart, Code Page
Mapping of Printed Bar Codes on page A-4, and scan the value and the SAVE
bar code from the Programming Chart inside the back cover of this manual. The
data characters should then appear properly.
