Ocr Modulo 36 Check Character; Ocr User-Defined Check Character - Honeywell 4800dr - Document Camera Barcode Manual

OCR Modulo 36 Check Character

Scan this symbol to program the OCR template for a simple modulo 36 checksum of the digits 0 through
9 and the letters A through Z.

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 deter-
mines 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:
Also enter the OCR template:
Enable the OCR-A font, then scan the following string:
The imager performs the following check character computation:
Since the result is zero, the message is considered to be valid, so the reader outputs the message:

Programming a User-Defined Check Character
1. Scan the Enter OCR Check Character barcode, below.
2. Enter the characters in order. For each character, look up the corresponding hex value from the
ASCII Conversion Chart (Code Page
the back cover of this manual to scan the two symbols for each hex value.
3. Scan the Save barcode on the inside back cover.
Example: To program the modulo 11 check character from example #8 on
font. Scan the Enter OCR Check Character barcode on
hex values in order:
