Reading Multi-Row OCR

The imager is capable of decoding multi-row OCR text.

Note: Reading rows longer than sixteen characters is not recommended.

Consider the following example. This example shows serial commands as they would be entered using Quick*View.

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

12345678

ABCDEFGH

First, enable the OCR-A font. To read the first row of OCR data, you would program the following template:

OCRTMP"dddddddd".

This template is the default OCR template. If you wanted to read the second line of data, you would use the following template:

OCRTMP"llllllll".

To read both lines of OCR at one time, use the variable r to indicate the start of a new row. All the other templating variables for the individual rows work the same as previously described. For instance, in the above example, you would use the following template to read both rows:

OCRTMP"ddddddddrllllllll".

To read the three rows below, you would use the template command "OCRTMP"ddddddddrllllllllrlllldddd".

12345678

ABCDEFGH

ABCD1234

OCR Check Character

You may want to print and verify a check character in order to enhance the security of your OCR application. The imager can be programmed for almost any type of check character. A number of presets are provided for common check character uses (e.g., modulo 10 and modulo 36).

Scan the OCR Modulo 10 or OCR Modulo 36 Check Character barcode to specify the type of check character used in the OCR strings you’re scanning. The imager will then only read OCR character strings with a valid check charac- ter. The imager transmits the OCR data without the check character data. You must specify the location of the check character in the template with a c.
