form the template expression, then End of Message) for each template in the multiple template string, using a
capital letter X as a separator between the templates.
For example, set the OCR Template as 99999XAAAAA to decode OCR strings of either 12345 or ABCDE.

OCR Check Digit Modulus
Parameter # 688 (SSI # F1h B0h)
This option sets OCR module check digit calculation. The check digit is the last digit (in the right most position) in
an OCR string and improves the accuracy of the collected data. The check digit is the end product of a calculation
made on the incoming data. For check digit calculation, for example Modulus 10, alpha and numeric characters are
assigned numeric weights (see OCR Check Digit Multiplier on page 269). The calculation is applied to the
character weights and the resulting check digit is added to the end of the data. If the incoming data does not match
the check digit, the data is considered corrupt.
The selected check digit option does not take effect until you set OCR Check Digit Validation.
To choose the Check Digit Modulus, such as 10 for modulo 10, scan the following bar code, then scan a three-digit
number from 001 to 099 representing the check digit using the numeric keypad in the Advanced Data Formatting
Guide. The default is 1.
