Code 93 Extended

ConnectCode Code 93 barcode font is able to support the full 128 ASCII characters. However, as the substitution mechanism is not easy to perform manually, it is recommended to use this barcode through the Software Encoder or the supplied VB macros.


Using the Code 93 barcode font

For example, to encode the data "12345678", you can key in the following in your text editor and choose the Code 93 barcode font.

Input (Using the Encoder or VB macros): 12345678

Manual Input: Å12345678Æ

ASCII 197 and 198 are used as the start/stop characters.

Output:



For example, to encode the data "ABCD", you can key in the following in your text editor and choose the Code 93 barcode font.

Input (Using the Encoder or VB macros): ABCD

Manual Input: ÅABCDÆ

Output:


If you are using the Encoder, it will automatically put in the start/stop characters for you and allow you to choose the optional check character.

Calculation of Code93 Modulo 47 Check Character

For example if the data "12345678" is to be encoded as a barcode. The check character is calculated as follows.
  
ASCII Characters12345678 
Code 93 Values12345678 
From the rightmost digit, multiply the value by a weight starting from 1. If the weight is greater than 20, restart the value from 1. Sum up all the values.
Check C Weight*8*7*6*5*4*3*2*1 
Check Digit C Sum :1*8 + 2*7 + 3*6 + 4*5 + 5*4 + 6*3 + 7*2 + 8*1 = 120
Modulo 47 Check Digit C :120 % 47 = 26 'Q'
Code 93 Values with Check Digit C1234567826
From the rightmost digit, multiply the value by a weight starting from 1. If the weight is greater than 15, restart the value from 1. Sum up all the values.
Check K Weight*9*8*7*6*5*4*3*2*1
Check Digit K Sum :1*26 + 2*8 + 3*7 + 4*6 + 5*5 + 6*4 + 7*3 + 8*2 + 9*1 = 182
Modulo 47 Check Digit K :182 % 47 = 41 '+'


The characters "Å12345678Q+Æ" can then be keyed in to the text editor with the appropriate font selected to generate a Code 93 barcode with check characters.
