OCR Programming
8-8 DuraLine™ 2D Imagers
To create this template, you would enable the OCR-A font. Scan the
Enter OCR Template
symbol (
page 8-16
). Scan the
d
from the
OCR Pro-
gramming Chart on page B-4
in the back of this manual three times, then
scan
2041424320
from the
Programming Chart on page B-5
(the hex char-
acters for “space,” “A,” “B,” “C,” “space”). Scan the
d
three more times,
then scan
Save OCR Template
(
page 8-17

string of three digits, space, “ABC,” space, then any string of three digits.
For example:

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 8-16
). Scan the
d
from the
OCR Pro-
gramming Chart on page B-4
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 8-17
). This would let you read either type of
format, for example:
99028650
or
9902XZ50
NOTE
If using PowerView to program, use the space
bar to designate a space and not the hex value
of 20.
