Hand Held Products 4410 manual Adding an OCR Check Character, Reading Multi-Row OCR

This template would then let you read data that began with 6 digits, and had an A, B, or C trailing. So you would be able to read:

654321ABC

or

654321BAC

or

654321CCC

Adding an OCR Check Character

You may want to program the scanner to read OCR strings that have a check character. The IT4410/4710 reads and strips out the OCR check character created using a modulo 10 or modulo 36 table. (Modulo 10 being digits 0-9, modulo 36 being digits 0-9 and characters A-Z.)

Scan the Modulo 10 or Modulo 36 Check Character bar code to specify the type of check character used in the OCR strings you’re scanning. The scanner will then only read OCR character strings with a valid check character. The IT4410/4710 transmits the OCR data without the check character data. You must specify the location of the check character in the template with a c.

Example F: You need to read any combination of 6 digits, with a modulo 10 check character in the 7th position. The template would be:

ddddddc

To create this template, you would scan the Modulo 10 Check Character symbol (page 4-10). Then scan the Enter OCR Template symbol, scan the d from the inside back cover 6 times, and scan the c once. Scan Save OCR Template (page 4-11). This template will let you read any combination of 6 digits with a correct check character after. (If the check character is invalid, the scanner will issue an error beep.) For example, the following string could be scanned:

0123455

and the output would be:012345

Reading Multi-Row OCR

The IT4410/4710 is capable of decoding multi-row OCR text. Consider the following example. This example shows serial commands as would be entered using Quick*View.

Example G: You need to read multiple rows of OCR data as shown below:

12345678 ABCDEFGH

4 - 8
