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:
551 ABC 983

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.
