Standard 2 Of 5 - PSC PowerScan Programming Manual

Standard 2 of 5

The Standard 2 of 5 symbology has the following programmable features:
Check Digit — calculate 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.
If the Check Digit is not calculated, the digit will be sent
regardless of settings for transmit or don't transmit. For
example, if you choose to Transmit Check Digit, but not
calculate, the scanner sends the Check Digit encoded in the
bar code without verifying its accuracy.
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 characters for reading specific length
labels only. Read the following details for specific Standard 2 of 5 limits.
Standard 2 of 5 Minimum Label Length — set the minimum
label length required for Standard 2/5 labels (range 01-50
(This feature is provided to improve read rate).
Variable Length — If you select variable length, the scanner will
recognize labels with between the minimum label length (see
the section titled, "Setting Standard 2 of 5 Fixed and Minimum
Label Lengths") and 50
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 characters between 01 and 50
• Set Second Fixed Length — use this label to instruct the
scanner that the next two programming labels you scan will
define the second fixed label length. Again, this setting can be
any number of characters between 01 and 50
• No Second Fixed Length — scan this label after setting the
first fixed length to instruct the scanner to recognize only the
label length chosen as the first fixed length.
1 For this symbology, the scanner will decode up to 50 characters, but the actual length read
will vary depending upon interface type, and bar code physical size and quality.
