Bar Code Types and Options
Introduction
Four bar code types are supported by the IMMAGE 800:
• Code 39
• Code 128
• Interleaved 2 of 5
• Codabar
The bar code scanner will read any of these bar code types, provided the type is
enabled in Bar Code Setup and the options match those defined for the bar code label.
The scanner will also automatically discriminate between the symbologies, so tubes
with bar code labels of different types may be intermixed in a run.
Code 39 Options
Check Digit: If a higher degree of data integrity is required, a check digit may be
enabled and added to the bar code ID. The check digit used is a Modulus 43, which is
the sum of all the character values and is the last digit of the bar code ID. Code 39
expects the check digit to be included in the final code length.
Large Intercharacter Gap: In Code 39, the intercharacter gap has a minimum value of
one times the width
of the narrow element and a maximum value of
three times the
width
of the narrow element, or 0.06 inches (0.152 cm), whichever is greater. This
feature should be enabled when the intercharacter gap exceeds four times the narrow
element width.
Fixed Code Length: If the sample IDs being used are all of the same length, Fixed
Code Length may be enabled to ensure that only one length of sample ID is accepted.
Define Code Length: When Fixed Code Length is enabled, the code length may be
defined as from 1 to 15 characters.
Code 128 Options
The options for Code 128 bar codes are fixed in the software and cannot be
reconfigured by the user. The IMMAGE 800 uses Code 128 formatting to read
BECKMAN COULTER bar coded cards and rack ID.
Fixed Code Length: disabled.
