Input Digit Limitation Function
The input limitation function is used to verify the master data and the extracted part of input data read with the
code reader.
Input Limitation Function
When the input limitation function is used, only the digits (input limit data) specified within the
data read by the code reader (input data) are verified with the master data. The input limitation func-
tion is also applied to data to be preset as the master data.
A B C D 1 2 3 4 5 6 B C D E 7 8 Input data
1 2 3 4 5 6 B C D E ............................. Input limit data
The following example shows how this function is used.
„ To verify only part of the bar code data
If you want to verify only “ABCD” within the following data, use the input limitation function to
preset only “ABCD” as master data.
1 2 3 4 A B C D 5 6 7 (* The circled digits are input limit data.)
By setting this, all of the data shown below, which contains the digits “ABCD” in this order, is veri-
fied as O.K.
