Interleaved 2 Of 5 - Wasp Bar Code Laser Scanner Programming Manual

I
NTERLEAVED
The Interleaved 2 of 5 symbology has the following programmable features:
Check Digit — calculate the Check Digit to verify that the
Check Digit contained in the barcode label is correct. If you
enable this feature, your barcodes 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.
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
Interleaved 2 of 5 limits.
Interleaved 2 of 5 Minimum Label Length — set the mini-
mum label length required for I 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 an even number of digits between 04
and 50 digits (Note: For IBM Interface the scanner recognizes
labels with an even number of digits between 04 and 32).
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
even number of digits between 02 and 50 digits. (Note: For
the IBM Interfaces the setting can be any even number of
digits between 02 and 32 digits).
