OCR Check Digit Multiplier

Parameter # 700 (SSI # F1h BCh)
This option sets OCR check digit multipliers for the character positions. For check digit validation, each
character in scanned data has an equivalent weight used in the check digit calculation. DS4308 OCR ships
with the following weight equivalents:
0 = 0 A = 10
1 = 1 B = 11
2 = 2 C = 12
3 = 3 D = 13
4 = 4 E = 14
5 = 5 F = 15
6 = 6 G = 16
7 = 7 H = 17
8 = 8 I = 18
9 = 9 J = 19
All other characters are equivalent to one (1).
You can define the multiplier string if it is different from the default.

ISBN uses modulo 11 for its check digit. In this case, 132 is divisible by 11, so it passes the check digit.
To set the check digit multiplier, scan the following bar code, then scan numbers and letters to form the
multiplier string from the alphanumeric keyboard in the Advanced Data Formatting Guide. Then scan
in the Advanced Data Formatting Guide.
