Good Read Setup
1. Select your specific data collection type from the icons over the Configuration Parameters
tree area: Code Collection, Code Combination, Presentation or Match Code. Not all data
collection types are available for all Operating Modes. Incompatible data collection types
will be shown in grey and cannot be selected.
The following example shows Code Combination. By default, the Expected Codes (when
more than one code type is selected), are in logical AND, which means that all codes are
required to be decoded to produce a Good Read condition.
2. If a Good Read condition should be produced when any single code is decoded,
independent from the others, then they need to be combined in logical XOR. To do this,
drag the code icon(s) from their relative Expected Code box into the Expected Code box
of the XOR combination you wish to create. Then delete the empty box by selecting it
with the mouse (highlighted) and pressing the delete key on your keyboard.
