Definition: The appropriate output will be activated if, at the end of the read cycle, the
symbol decode count is below this setting.
Note: To activate this feature the reader must be in Decodes per Trigger
mode. To put the reader in this mode during the read cycle and the Trend
Analysis operation, the Decodes per Trigger status in the quality settings
must be enabled. Enabling this setting will also append the decode count to
the symbol data.
