Chapter 4 — Enabling and Configuring Symbologies
After enabling one or more symbologies, you can use the bar codes in the following sections to configure the symbology options and features.
Code 39/PharmaCode 39 Options
This section describes the Code 39 options and contains the programming bar codes you can use to configure those options.
About 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
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.
