HandHeld Entertainment 4600rp OCR User-Defined Check Character, OCR Modulo 10 Check Character

Example: You need to read any combination of seven digits, with a modulo 10 check character in the eighth position. The template would be:

dddddddc

To create this template, you would enable the OCR-A font. Scan the Modulo 10 Check Character symbol. Then scan the Enter OCR Template symbol, and scan the d from the OCR Programming Chart seven times, and scan the c once. Scan Save OCR Template (page 9-13). This template will let you read any combination of six digits with a correct check character after. (If the check character is invalid, the data is discarded.) For example, the following string could be scanned:

01234569

and the output would be: 0123456

OCR User-Defined Check Character

You can customize the check character calculation to suit your application. Each character of the check character alphabet can be programmed in its proper order. The number of characters you enter determines the modulo value for the calculation. By default, the check character computation is unweighted, but the imager also supports two weighted modulo 10 checking schemes.

Example: To program a modulo 11 check character, you would enter the following 11 characters in order:

9 - 8
