Instruction manual

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.”
Sum of Products Calculation
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
3. Next, the product of each digit is added together. This is the sum of the
products.
20 + 2 + 6 + 6 + 16 + 5 + 4 + 3 + 36 = 98
4. Divide the sum of the products by the modulus (10 in this case), only to
the whole number. The balance is called the remainder.
