Bar Code Label Formats
The Bar Code Reader on the CELL-DYN 3200 System can read all four label types
listed below. Code size, collection tube length, and cap style limit the number of
digits to the following maximum numbers:
A minimum of three digits is required.
• Code 39 — 9 digits
• Code 128 — 11 digits
• Interleaved 2 of 5 — 10 or 12 digits only
• Codabar — 10 digits
NOTE:
The maximum number of digits includes any check digits within
the code. For example, if one check digit is used in Code 39, then
only 8 digits can be used for the rest of the code.
Bar Code Check Digit Formats
Bar code Check Digits are used whenever the instrument is to read a specific type
of bar code. To enable or disable the check digit option, refer to
Check Digit specifications are as follows:
• Code 39 - The modulus 43 sum of all the character values in a given message
• Code 128 - The check digit is built into the Bar Code Reader.
• Interleaved 2 of 5 - The check digit is the complement of the weighted sum
of the digits modulo 10. To determine the weight of the digits, multiply every
other digit by 3, starting with the first.
• Codabar - The modulus 16 sum of all the character values in a given message.
NOTE:
If a specific check digit option is selected and turned ON, the Bar
Code reader will read only bar codes in that specific format. If more
than one format will be used on the instrument, it is recommended
that the check digit option be turned OFF.
