Product Reference Guide 269
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 occured.
Timeout (Scanning Active Time option): Specifies the maximum duration for the reading
phase. Selections: from 1 to 255 seconds in 1 second increments.
Automatic Mode
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 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.
Automatic/Trigger Object Sense
Automatic/TOS mode is the same as Automatic mode but with the illumination system
normally off*. As an object or bar code enters the reading area, illumination is turned ON.
Illumination will return to the Presentation Illumination 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 86
