Code 128
This code uses four to 16 data digits on the LH 700 Series and four to 11 data digits for the
SlideMaker bar-code label printing.
The checksum character immediately precedes the stop character. The checksum character
used with Code 128 must conform to the AIM USS 128 checksum generation procedure. DO
NOT use the following values because they are not recognized as valid values:
The checksum value (see the following table) is equal to the modula 103 sum of the value of
the start character and the weighted values of the data/special characters. The weights are one
for the first data/special character and continuing with two, three, four and so forth for the
following data/special characters.
For example, a label contains a START character (Code C), Data (25), a Check character and a
STOP character. The value of the Start character C is 105, and the data character for 25 is 25.
The weight of the first data character is one, so the check character value is calculated as follows:
105 + (25 x 1) = 130
where 105 and 25 are the values and 1 is the weight.
The checksum is equal to 130 modula 103 (the remainder of 130 divided by 103):
130 ÷ 103 = 1, REMAINDER 27
Therefore the check character equals character value 27, which is; in Code Set A.
For additional information on this procedure, refer to AIM USS-128 Rev. 1986, published by
AIM, Inc., 1326 Freeport Road, Pittsburgh, PA 15238.
Code set A 0, 3, 32, 59, 60, 61, 64 through 102
Code set B 0, 3, 32, 59, 60, 61, 64, 91 through 102
Code set C 100 through 102
IMPORTANT Inaccuracies will occur when printing a SlideMaker slide label using certain Code 128
characters. DO NOT use the following characters when printing a slide label using Code 128: question mark
(?), asterisk (*), or space.
