4-7 Digit Limit Function Settings
The Digit Limit Function is useful if you are scanning barcodes with a certain number of digits
n and want to ignore barcodes with more or fewer digits.
Depending on the application, the BL-N70 family offers two Digit Limit Options:
z LIMIT ALL
Applies to ALL enabled symbologies. All barcodes of length n characters, will be
scanned. Any barcode with < > n characters will be ignored.
To set the number of digits, scan three decimal barcodes from page 4-24.
z LIMIT SELECT
Up to 7 different limits can be activated at the same time. For example, you can limit all
ITF codes to 14 digits. At the same time, you can limit all Code 128 barcodes to 26
characters. All ITF codes <>14 digits are ignored. All Code128 codes <>26 digits will be
ignored.
Conditions:
• Can set up to 7 total limits
• Can use multiple limits for same symbology:
example: Allow Code 39 barcodes of length 7 to 10 digits (4 limits used; 7, 8, 9, 10)
• Individual limits must be scanned in order, starting with limit #1 codes first, then #2 and
so on. Do not jump around.
Example 1: Read 10 digits for CODE39 and 14 digits for ITF
