Phase Off Event:
Specifies whether the reading phase is closed on a timeout
or phase off event.
The following selections are available:
• Trigger Stop: the reading phase ends when the serial stop character (or
string) is received. Timeout is disabled.
• Timeout: the reading phase ends when the timeout is expired. Serial
stop character (or string) is ignored.
• Trigger Stop - Timeout: the reading phase ends when the first event
occurred.
Timeout (Scanning Active Time option):
Specifies the maximum duration for the
reading phase. Selections: from 1 to 255 seconds in 1 second increments.
Automatic (Always On)
In Automatic mode, 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 guar-
antee 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.
Automatic (Object Sense)
Automatic/TOS mode is the same as Automatic mode but with the illumina-
tion system normally off*. As an object or bar code enters the reading area,
illumination is turned ON. Illumination will return to the Presentation Illumi-
nation Control setting as the reading phase is closed (see Automatic Mode
above).
*Default. The illumination can be programmed for several different operation
states (off, dim or on) while the reading phase is not active. See
"Presentation
Illumination Control" on page 72.
