ddd2041424320ddd

To create this template, you would enable the OCR-A font. Scan the Enter OCR Template symbol (

page 7-9

). Scan the d

from the

OCR Programming Chart

in the back of this manual three times, then scan 2041424320 from the

Programming Chart

on the inside back cover (the hex characters for “space,” “A,” “B,” “C,” “space”). Scan the d three more times, then scan Save
OCR Template

(

page 7-9

). This would let you read any string of three digits, space, “ABC,” space, then any string of three

digits. For example:

551 ABC 983

Note: If using Quick*View to program, use the space bar to designate a space and not the hex value of 20.

4. Exit OCR Template Editor

Scan Save OCR Template to save your entries. Discard OCR Template exits without saving any OCR Template changes.

Stringing Together Multiple Formats
(Creating “Or” Statements)

You may want to program the imager to accept many OCR formats. To do this, you would string together each format with a “t.”

This tells the imager to read optical characters that match any one of the formats in the template.
Example: You need to read any combination of eight digits, or a combination of four digits, two uppercase letters, and two digits.

The template would be:

ddddddddtddddlldd

To create this template, you would enable the OCR-A font. Scan the Enter OCR Template symbol (

page 7-9

). Scan the d

from the

OCR Programming Chart

in the back of this manual eight times, then scan the t to create the “or” statement. Then

you would scan the characters for the second template. Scan d four times, scan l two times, then scan d two more times.

Scan Save OCR Template (

page 7-9

). This would let you read either type of format, for example:

99028650

or

9902XZ50

You can string together as many templates as you need.

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 (

page 7-9

). 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 7-9

).

Scan 414243 from the

Programming Chart

(the hex characters for “A,” “B,” and “C”). Scan Save OCR Template (

page 7-9

).

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

hex code for a space
