NOTE:
The percent sign (%) is valid only on Recall Search screens, where
it is used as a wildcard character in the search.
•
When creating barcodes, use only the characters that are allowed for the
corresponding input fields.
•
The system accepts data input of user-entered information from
user-supplied barcodes read on the external barcode reader for the
following Operator Management screen fields for adding or editing:
•
Operator ID
•
Access Code
•
A search to recall the samples associated with the data entered by
barcode is not case sensitive.
•
The system accepts data input of user-entered information from user
supplied barcodes read on the external barcode reader whenever a user is
prompted to enter an Access Code.
The barcode symbols, and the labels themselves, must meet certain
specifications, detailed below:
Number of Characters:
1–24 data characters. (A maximum of 24 characters
can be displayed, stored, printed, and transmitted by the DCA Vantage
system.)
The Interleaved 2 of 5 (I2of5) symbology requires an even number of
characters. If a scanned barcode has an odd number of characters, the
symbology adds a leading zero, up to the maximum of 24 characters. For
example, 1 becomes 01.
Narrow Bar Width:
0.15–0.51 mm (0.006–0.02 inches). It is better to be closer
to the upper limit (0.51 mm/0.02 inches), as long as the entire barcode can be
contained within the maximum length.
This measurement affects both the symbol length and how far away from the
label you can hold the handheld reader. If the narrow bar width is at the
minimum, the symbol length can be no greater than 90 mm (3.5 inches),
including quiet zones, and the reader can be held no more than 75 mm
(3 inches) away.
Narrow to Wide Ratio:
Must be within the specifications for the format being
used. This is generally 2.0–3.0.
Symbol Length:
Variable. See
Narrow Bar Width
for more information.
Quiet Zone:
Minimum of 10 times the narrow bar width at each end of the
symbol.
Symbol Height:
Minimum of 10 mm (0.40 inches).
Total Size of Label:
May be greater than the size of the symbol to allow for
printing of human readable information. Printing of the specimen ID number in
alphanumeric digits is strongly recommended.
