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 9-14 ). 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 9-15 ). 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 9-
14 ). 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:
