OCR Programming8-10 PowerScan ® 7000 2DConsider the following example. This example shows serial commandsas they would be entered using PowerView.Example: You need to read multiple rows of OCR-A data as shown below:12345678ABCDEFGHFirst, enable the OCR-A font. To read the first row of OCR data, youwould program the following template:OCRTMP"dddddddd".This template is the default OCR template. If you wanted to read thesecond 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 thestart of a new row. All the other templating variables for the individualrows work the same as previously described. For instance, in the aboveexample, you would use the following template to read both rows:OCRTMP"ddddddddrllllllll".To read the three rows below, you would use the template command"OCRTMP"ddddddddrllllllllrlllldddd".12345678ABCDEFGHABCD1234.OCR Check CharacterYou may want to print and verify a check character in order to enhancethe security of your OCR application. The imager can be programmedfor almost any type of check character. A number of presets are providedfor common check character uses (e.g., modulo 10 and modulo 36).Scan the OCR Modulo 10 or OCR Modulo 36 Check Character bar code tospecify the type of check character used in the OCR strings you’re scan-ning. The imager will then only read OCR character strings with a validcheck character. The imager transmits the OCR data without the checkcharacter data. You must specify the location of the check character inthe template with a c.Example: You need to read any combination of seven digits, with a modulo 10 checkcharacter in the eighth position. The template would be:
