Honeywell 4800dr manual OCR User-Defined Variables, Reading Multi-Row OCR

OCR User-Defined Variables

You can create up to two of your own user variables for an OCR template. These variables will represent any OCR readable characters. The user-defined variables are stored under the letters “g” and “h.” Cre- ating a user variable follows the same steps as creating a template, but instead of scanning the Enter OCR Template symbol, you scan the Enter User-Defined Variable symbol (page 7-10). The letters g and h can then be used in an OCR template to define the variable you specified.

Example: You need a variable to represent the letters “A,” “B,” or “C.” The template for this variable would be:

414243

To create this template, you would enable the OCR-A font. Scan the Enter User-Defined Variable g symbol (page 7-10). Scan 414243 from the Programming Chart (the hex characters for “A,” “B,” and “C”). Scan Save OCR Template (page 7-10). This will let you read either A or B or C in any position where you place the g. For example, you could create the following template:

ddddddggg

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

654321ABC

or

654321BAC

or

654321CCC

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".
