A.7 CODE128 Specifications
Setting No. of Digits
• The start/stop character and check digit are not included in the number of dig-
its.
• FNC1 to 4 (Function codes), SHIFT, and CODE-A to -C should not be added to
the number of digits.
• The number of digits setting range varies depending on the start character
(CODE-A to -C).
CODE-A, B: 1 to 32
CODE-C: 2 to 64

Data Transmission
• The start/stop character and check digit cannot be sent.
• FNC1 to 4 (Function codes), SHIFT, and CODE-A to -C cannot be sent.
• Control codes are sent.
Registration of Preset Data
The number of characters that can be registered as preset data is up to 32 digits
for CODE-A or CODE-B, and up to 64 digits for CODE-C, as described above.
When ! or ? is registered as preset data, it functions as the Preset “!” “?” Function,
as described on page 20 .
Since CODE128 can represent all ASCII codes as bar code data, ! or ? can also
be represented as bar code data.
To register ! or ? as preset data, send \! or \? to differentiate it from the Preset “!”
“?” function.
To register \ as preset data, send \\.
Example: To register 123 \!?ABC as preset data, send the following command (see
page 57).
WP68123 \\\!\?ABC
Control codes (00h to 2Fh of the ASCII code table, such as and <STX>), start/
stop character, check digit, FNC1 to 4 (function codes), SHIFT or CODE-A to-C
cannot be registered as preset data. (Data comparison is also impossible.)
