Operating Mode
The following Operating Modes (Reading Modes) are supported:
On Line (Single Trigger)
In On Line mode, the reading phase is defined as the time between the
Phase ON and Phase OFF events. The Phase events can be generated by an
external input (trigger) or by the Trigger button. While in this mode the
scanner activates reading only during a reading phase.
On Line mode allows the following configurations:
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 trigger event
stops.
Timeout is disabled.
•
Timeout: the reading phase ends when the timeout is expired. Trigger
stop is ignored.
•
Trigger Stop - Timeout: the reading phase ends when the first event
occur
ed.
Timeout: Specifies the maximum duration for the reading phase. Selections:
from 1 to 255 seconds in 1 second increments.
Serial On Line
In Serial On Line mode, a reading phase is defined as the time between two
events: phase on and phase off, generated by a message sent from the host
interface to the scanner. While in this mode the scanner activates reading
only during a reading phase. The message (character or string) is user pro-
grammable.
Serial On Line mode configurations:
Serial Start Character (or String): Specifies the string message to be sent over
the host interface to activate the reading phase.
Serial Stop Character (or String): Specifies the string message to be sent over
the host interface to stop the reading phase.
The Serial Start/Stop Characters must be different and must not
contain reserved characters (see Appendix E, Host Configuration
Reserved Characters).
See "Manual Trigger Control" on page 71 to configure control of
manual triggering.
