Light Pen Emulation Feature
Some light pen decoders require an extra toggle of the data line before they
will recognize a border condition. Others require that while idle, the data line
be the polarity of a bar instead of a space. Enabling this feature can satisfy
these requirements.

Code Type Selections
The following bar codes are used to program the scanner to read different
types of bar codes. The default setting for all of the bar code types is enable.
To improve reliability, disable the code types that will not be used. This will
not decrease the time it takes for the scanner to scan a bar code, but it will
prevent the operator from accidentally scanning bar code types that should not
be included in your application.
