66 PowerScan ™ Scanner
Symbology Options
After enabling the desired symbology, you can use the bar codes labels
in this section to configure the specific options/features required for
your site.
Code 39/PharmaCode 39
Code 39
Options
The Code 39 symbology has the following programmable features:
• Check Digit
• Start/Stop Characters
• Code 39 Full ASCII
• Minimum Label Length
• Read Verification
• QuadraLogic Decoding
Check Digit 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.
Start/Stop
Characters
Start/Stop Characters selects either Send or Don’t Send depending on
your host’s interface requirement.
Code 39 Full
ASCII
Code 39 Full ASCII enables or disables the ability to decode Code 39
Full ASCII labels.
Minimum Label
Length
Minimum Label Length sets the minimum label length required for the
Code 39 symbology. This feature causes the scanner to ignore small
label segments, reducing the possibility that a portion of a good label is
incorrectly seen as an entire label.
Read Verification Read Verification is the number of times the scanner is required to read
the bar code data before sending the label data to the host.
QuadraLogic
Decoding
QuadraLogic Decoding directs the scanner to decode labels with wide-
spread problems of spots, voids, and/or non-uniform widths.
To optimize your scanner’s performance activate this option only for
symbologies for which it is necessary.
There are many additional ways to configure the scanner to read and
decode extremely poor labels. Contact your sales representative or ser-
vice provider for other advanced QuadraLogic Decoding settings.
