You can string together as many templates as you need.

Creating a User-Defined Variable

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

would be:

414243

To create the template, you would scan the Enter User-Defined Variable g symbol. Scan 414243 from

Appendix D (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 6 digits, and had an A, B, or C trailing. So you

would be able to read:

654321ABC

654321BAC

654321CCC

Reading Multi-Row OCR

The OEM Engine 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

To read the first row of OCR data, you would menu 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 rto indicate the start of a new row. All of 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".
