Honeywell 4800dr manual OCR Isbn Application Example, 0128454

Then scan the string below:

0128454

The reader performs the check character computation below:

(0 x 1 + 1 x 2 + 2 x 1 + 8 x 2 + 4 x 1 + 5 x 2 + 4 x 1) modulo 10

=(0 + 2 + 2 + (1 + 6) + 4 + (1 + 0) + 4) modulo 10

=0

Since the result is zero, the message is considered to be valid, so the reader outputs the message: 012845

OCR ISBN Application Example

One application of OCR is to read the ISBN characters typically encoded using the OCR-A or OCR-B font. This is especially useful when the ISBN number is not encoded in an EAN-13 barcode. The follow- ing example shows how to configure the imager to read the ISBN strings on books in Japan. After you have followed the steps below, you will be able to scan the following ISBN number or the additional data below it, depending on the line of text at which the imager is aimed.

1.Scan the OCR-B On barcode on page 7-1.

2.Program the user-defined variable “g” to comprise the ten digits plus the dash: 0123456789-

3.In Japan, it is common for two fields to follow the ISBN number, the three digit price field, and the four digit price field. The first field typically starts with a “C” (uppercase c), followed by four digits. The second field typically starts with a “P” or a yen symbol, followed by three or four digits, followed by an “E.” Program the user-defined variable “h” to comprise the “P” and the yen symbol (represented by a backslash).

P\

4.Scan the symbol below to set up three templates to handle the ISBN number, the three digit price field, and the four digit price field.
