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.” Creating 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. 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. Scan 414243 (the hex characters for
“A,” “B,” and “C”). Scan Save OCR Template . 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:
Reading Multi-Row OCR
The ZB-3062 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:
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".
