9 - 8 IMAGETEAM™ 2020/4620 System Manual

To create this template, you would enable the OCR-A font. Scan the
Enter
User-Defined Variable
g
symbol (page9-14 ). Scan
414243
from the
Programming Chart (the hex characters for “A,” “B,” and “C”). Scan
Save
OCR Template
(page 9-15). 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

or

654321CCC

Reading Multi-Row OCR
The IT4620 is capable of decoding multi-row OCR text.
Note: Reading rows longer than sixteen characters is not recommended.
Consider the following example. This example shows serial commands as they
would be entered using Quick*View.
Example: You need to read multiple rows of OCR-A data as shown below:

12345678

ABCDEFGH

First, enable the OCR-A font. To read the first row of OCR data, you would
program 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
r
to indicate the start
of a new row. All 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".
