3.2 Algorithm Control
Click the “Algorithm” page of the main form, as figure 13. The Algorithm pane is used to
view, the parameters for the selected singulation algorithm. The user may select Fixed Q,
Dyanmic Q, Dynamic Q Adjustable and Dynamic Q Threshold from the Active Algorithm
combo box. Then, you can edit parameters and click “save” button to refresh the values
displayed in the Algorithm Settings View panel.

1. FixedQ : Fixed Q algorithm. The items as follows:
1: qValue: The Q value to use. Valid values are 0 to 15, inclusive.
2: retryCount: Specifies the number of times to try another execution of the
singulation algorithm for the specified session/target before either toggling
the target (if toggleTarget is non-zero) or terminating the inventory/tag access
operation. Valid values are 0-255, inclusive.
3: toggleTarget: A flag that indicates if, after performing the inventory cycle for the
specified target (i.e., A or B), if the target should be toggled (i.e., A to B or B to
A) and another inventory cycle run. A non-zero value indicates that the target
should be toggled. A zero value indicates that the target should not be
toggled. Note that if the target is toggled, retryCount and repeatUntilNoTags
will also apply to the new target.
4: repeatUntilNoTags: A flag that indicates whether or not the singulation algorithm
should continue performing inventory rounds until no tags are singulated. A
non-zero value indicates that, for each execution of the singulation algorithm,
