4
Examples:
1.
2+3+4+7+1+3 = 20
20 ÷ 16 = 1, REMAINDER 4
The value 4 corresponds to character 4; therefore, the checksum is 4 and the final
decoded message is 2347134.
2.
11+11+13+13+15+15+15+15 = 108
108 ÷ 16 = 6, REMAINDER 12
The value 12 corresponds to character :, therefore, checksum is :, and the final decoded
message is: $$//++++:
NW7 Decoding
This code uses three to 16 numeric data digits.
The value assigned to each of the characters is presented in the following table.
Table 4.27 NW 7 Character Value Table
The checksum technique is:
r
The data digit value that is the difference between 11 and the Mod 11 sum of the
weighted values of the data digits is used as the check digit. The start and stop digits are
not used as part of the checksum calculation.
r
NW7 is made up of 1 start digit, 16 data digits and 1 stop digit.
r
The checksum digit immediately precedes the stop digit.
WEIGHTED MODULUS 11:
MESSAGE 2 3 4 7 1 3
VALUE 2 3 4 7 1 3
MESSAGE $ $ / / + + + +
VALUE 11 11 13 13 15 15 15 15
