PQ-8P, PQ-8S

NOTE

Since Interleaved 2 of 5 symbols are created from data-character pairs, the number to be encoded must have an even number of digits. If an odd number of data characters (including the optional check digit) is entered, the PQ-8 adds a “0” to the beginning of the bar code. If an even number of data characters (including the optional check digit) is entered, the PQ- 8 prints the bar code exactly as it is input.

Code 128

Code 128 has three unique character subsets (code A, B, and C) shown in the table on the following pages. When entering data representing Code 128 bar code, follow these two steps:

1.Define which code set you want to use: type “A” to represent code A; type “B” to represent Code B; and type “C” to represent code C.

2.If you are using code set B, enter the data characters directly. The ~ character and other special characters are represented by the Symbol Character Value found in the left column of Table 6-4.

If you are using code set A or C, enter the Symbol Character Value found in the left column of the table. Each character is represented by two digits or a ~ followed by a digit. For example, to bar code the

character “&” using Code Set A, type 06.

Maximum number of data characters: Valid characters:

30 (includes special characters) Differs with selected code set, see Table 6-4.

Example: ¬B2,3,2,1,1,0,ABCDEFGHIJKLMNOPQRSTUVWXYZ¬B
