TECHNICAL INFORMATION, ID Bar Code
C-28 Sysmex SF-3000 Operator's Manual -- Revised September 1995
3.7 Applicable Characters
The valid characters for the ID bar code system are numerals (0-9) and a hyphen (-).
CODABAR (NW-7) and CODE-39 may use the other characters such as alphabets. The
SF-3000 ID system does not recognize them. The ID number allows up to thirteen
digits. The application of hyphens in an ID number should adhere to the following rules:
(1) Hyphens must be placed between other characters.
(2) The ID number cannot begin or end with a hyphen.
(3) Hyphens are included as part of the allowable maximum number of 13 characters.
(4) When calculating check character of an ID number that includes hyphens, the
hyphen in CODABAR (NW-7) is calculated as 0 (zero), and hyphen in CODE-11
is calculated as 10 in decimal. In the CODE-39 symbology, the hyphen is
calculated as 0 (zero) for Modulus 11, and as 36 for Modulus 43.
(5) ITF cannot recognize the hyphen since this symbology does not allow such a
character.
3.8 Effective Bar Code Length
For the NW-7 (CODABAR) and CODE-39 symbologies, the ID number can consist a
minimum of 1 digit, and a maximum of 13 digits. For the other symbologies, the
minimum number of digits depends on the symbology used and the application of the
check-digit.
