Checksum Verification: 
The checksum is optional and presented as the sum 
mod 43 of the numerical value of the data digits.
Checksum Transmission: 
When this option is enabled, the QS2500 will 
transmit the checksum.
Maximum/Minimum Code Length: 
Each symbology has own maximum and 
minimum code length, which can be set to qualify data entry. The length 
is defined as the actual bar code data length to be sent. Labels with lengths 
below the minimum or above the maximum will be rejected. If the maxi-
mum and minimum code lengths for a specific symbology are both set to 
zero, the global minimum and maximum code length settings are in 
effect.
Truncate Leading/Ending:

Format: 
The Full ASCII Code 39, an enhanced set of Code 39, uses a total 
of 128 characters to represent Full ASCII code. Each Full ASCII Code 39 
character is a combination of one of the characters +,%, $ and / with an 
uppercase alphabetical character (A to Z).
Start “*”
Data Digits (Variable)
Checksum (Optional)
End “*”
NOTE
Make sure that the minimum length setting is not greater than the maxi-
mum length setting; otherwise, all the labels of the symbology will be
unreadable. You can set the same value for both minimum and maximum
length to force decoding of only bar codes of a certain length.
