A8. "weights" String of digits used for calculation. A weight string is a group of two or more numbers that is applied to a field. The number of digits in this string should equal the number in fld_length.

Enclose in quotation marks. Range: 0 - 2710 (0 - 100 for 9403/9805).

Example {A,1,A,R,10,5,P,"65432" p }

Adds check digit scheme number 1 to the printer’s memory. The modulus is 10, the maximum number of characters in the field is

5.The check digit is calculated by using the Sum of Products and the string of digits used in the calculation is "65432."

This is an example of how the printer uses Sum of Products to calculate a check digit for this data:

5 2 3 2 4 5 2 1 9

1.Weights are applied to each digit, starting with the last digit in the weight string. They are applied right to left, beginning at the right-most position of the field. Remember, a weight string must contain at least two different numbers. This example has a weight string

of 1,2,3,4.

field:5 2 3 2 4 5 2 1 9

weight string: 4 1 2 3 4 1 2 3 4

2.Each digit in the field is multiplied by the weight assigned to it:

field:5 2 3 2 4 5 2 1 9

weight string: 4 1 2 3 4 1 2 3 4

products: 20 2 6 6 16 5 4 3 36
