Forced Account Code F-7
Programming (cont’d)
Note:
Bit 0 through bit 7 may be used when 8-digit FORCED ACCOUNT CODES are assigned in the AATC
command.
System Data 1, Index 13. Each bit in Index 13 directly correlates to a digit in the FORCED
ACCOUNT CODE assigned in AATC, and will determine the second digit of the Check Sum method.
Again pick any bits, 0 to 4, but not the same combination of bits as picked in Index 12.
System Data 1, Index 14. Determines the algorithm used to calculate the last two digits of every
FORCED ACCOUNT CODE. Only decimal numbers may be used in this index; hexadecimal values
A to F may not be assigned.
System Data 1, Index 14 = XY. X and Y represent any arbitrarily chosen decimal digit 1-9; Y is used
determine the first digit in the Check Sum method and X is used to determine the second digit in the
Check Sum method. The following data, 37H; has been used for the example calculation:
Note:
If only one digit is to be added via the Check Sum method, Index 13 data will be 00H and Index 14, digit X
(bits 4-7) = 0.
EXAMPLE CALCULATION
In AATC, 26428 has been assigned.
In System Data 1, Index 12, bits 0 and 3 were chosen; 26428
2 + 2 = 4.
The decimal value of bits 0-3 of Index 14 = 7.
4 + N = 7. N = 3.
7 is obtained as any whole number greater than 4 that ends with a 7, the decimal value as determined in
Index 14, bits 0 to 3.
In AATC, 26428 has been assigned.
In Index 13, bits 4 and 1 were chosen; 26428
8 + 6 = 14.
The decimal value of bits 4-7 of Index 14 is 3.
14 + N = 23. N = 9.
23 is obtained as any whole number greater than 14 that ends with a 3, the decimal value determined in
Index 14, bits 4 to 7.
The FORCED ACCOUNT CODE will be 26428-39.
