OCR Check Digit Multiplier

Parameter # 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. DS35787 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.
