Calculate checksum characters as follows: 

1.  Add the characters in the string (not including the checksum character). 
2.  Subtract 10 from the sum obtained above. Continue subtracting 10 until the remainder is less than 

10. 

3.  The remainder obtained above is the checksum. Enter this digit in the checksum position. 

1.  Add the characters in the string (not including the checksum character). 
2.  Subtract 36 from the sum obtained above. Continue subtracting 36 until the remainder is less than 

36. 

3.  Subtract the remainder obtained above from 36. The value obtained is the checksum. Enter this 

character in the checksum position. 

Digit / Alpha values are defined as follows for modulo 36: 
0 – 9 = 0 – 9;  A = 10, B = 11, … Z = 25 

Direction (Orientation) – this parameter is ignored

Description

0 left to right 

1 top to bottom 

2 right to left 

3 bottom to top 

Orientation. Decoder reads 

OCR fonts in any orientation, 

but setting this parameter 

correctly can increase 

decoding speed. 

 

1. 

To read a combination of 6 alpha and numeric characters use the following template: 

  

aaaaaa 

2. 

To read the same string with a modulo 10 check digit in the 7

th

 character position, use the 

following template: 

  

aaaaaac 

 

Then enter 0123456789 for parameter 6. 

3. 

To read either a string of 6 alphabetic letters OR a string of 8 numeric digits, use this 
template: 

 

 lllllltdddddddd 

 

Note the use of the “t” to separate the first template from the second. 

4. 

To read multiple rows of OCR data as shown below: 

  

123450 

  

ABCDEF 

 

Either of the following templates could be used: 

 

 ddddddrllllll or aaaaaaraaaaaa 

 

Note the use of the “r” to define the position of the second row.
