The length of the data depends on the IA. Some fields are of a fixed length and others are variable.
All positions must be completed in fixed-length fields.
If not all the positions are completed in variable-length fields, the FNC1 character must be entered
at the end in order to indicate end of field.
CHANGE (Change A, Change B and Change C) is a special character that permits the code type
to be changed within an EAN 128. Therefore, when a change character is encountered, the EAN
128 will be printed with the new code specified until another change character is encountered.
The Change character only makes a change between sets of A and B characters and only affects
the following character found after the Change character.
IMPORTANT: If IA 10 is used (batch number) it is not necessary to include the data field after
the identifier, LP2550 automatically inserts the batch number of the machine.
It is not necessary to enter a STOP character. The LP-2550 automatically enters a STOP
character when a space is found instead of an application identifier.
EXAMPLE OF EAN 128:
This barcode was programmed as follows:
START C + FNC1 + identifier
+ DATA +
identifier + DATA
(TOT3 + 2) + (TOT3 + 7) + (10 ) + (12345678901234567890) + (11) + (110201)
In this example, the machine batch number is 12345678901234567890. If the batch number has
less than 20 characters, the FNC 1 character must be entered at the end of the field.
(TOT3 + 2) + (TOT3 + 7) + (10 ) + (1234 (TOT3 + 7)) + (11) + (110201)
If the batch number contains letters as well as numbers, the EAN 128 must be edited so that it
occupies the least possible space.
If, for example, the batch number is: ABCD1234
In this case the best form of programming would be:
(TOT3 + 1) + (TOT3 + 7) + (10 ) + (ABCD + (TOT3 + 5) + 1234+ (TOT3 + 7)) + (11) +
(110201)
In this case, the EAN 128 is commenced with a set of B characters because there are capital
letters in the data (set A could also be used at the beginning). As there are digits after the letters,
and there are an even number of digits, set C is then used.
