Specifies the maximum duration for the
reading phase. Selections: from 1 to 255 seconds in 1 second increments.
Always On:
In Always On, the scanner is continuously scanning. When a label enters the reading
zone and is decoded, no more decodes and reading phases are allowed until the label
has left the reading area. In order to guarantee identification of the code in the reading
zone, a threshold specifies the number of scans after the successful decode that the
scanner will wait before rearming the reading phase. The transmission of the decoded
label depends on the configuration of the Transmission Mode parameter.
