Standard 2 of 5
The Standard 2 of 5 symbology has the following programmable features:
Check Digit — calculates the Check Digit to verify that the
Check Digit contained in the bar code label is correct. If you
enable this feature, your bar codes must contain a Check Digit.
You may also choose to transmit or not transmit the Check
Digit independent of whether the Check Digit is calculated by
the scanner. The Transmit Check Digit will have no effect
unless the Compute Check Digit feature is enabled. If you
choose Don’t Compute Check Digit, the scanner sends the
Check Digit encoded in the bar code without verifying its
accuracy. If you choose both Compute Check Digit and Don't
Transmit Check Digit, the scanner will remove the Check
Digit's contents before sending the bar code data to the host.
The Transmit Check Digit option has no effect unless the
Compute Check Digit option is enabled.
Label Format — provides the selection between fixed or
variable length labels. If your application has labels with
specific fixed lengths, we recommend selecting fixed lengths
to improve read rate and avoid short reads.
You can select any valid number of digits for reading specific
length labels only. Read the following details for specific
Standard 2 of 5 limits.
Standard 2 of 5 Label Lengths
Standard 2 of 5 Minimum Label Length — sets the minimum
label length required for Standard 2/5 labels (not including
the check character). This feature is provided to ignore small
label segments, reducing the possibility that a portion of a
good label is incorrectly seen as an entire label.
Variable Length — if you select variable length, the scanner will
recognize labels with a number of digits between 01 and 50 * digits.
Fixed Length — if you select fixed length, there are three labels
for programming your scanner to read either one or two fixed
lengths. The labels are:
• Set First Fixed Length — use this label to instruct the scanner
that the next two programming labels you scan will define the
first fixed label length. This setting can be any number of digits
between 01 and 50 * digits.
* For variable length symbologies, the QS6000/6000 Plus will decode up to 50 characters, but
the actual length varies with label size and quality. The IBM POS interface is limited to 32
characters labels.
