Operating Modes
Scan Mode
The imager can be set to operate in one of several scanning
modes. See the PRG for more information and settings for
any of the options:
Trigger Single (Default) —
This mode is associated with typical
handheld reader operation. When the trigger is pulled, illumi-
nation is turned on and the scanner attempts to read a label.
Scanning is activated until one of the following occurs:
• the programmable “maximum scan on time”
1
has
elapsed
• a label has been read
• the trigger is released
Trigger Pulse Multiple —
Scanning begins when the trigger is
pulled and continues after the trigger is released, until the
trigger is pulled again or until the programmable “maximum
scan on time”
1
has elapsed. Reading a label does not disable
scanning. Double Read Timeout
1
prevents undesired multiple
reads while in this mode.
Trigger Hold Multiple —
When the trigger is pulled, scanning
starts and the product scans until the trigger is released or
“maximum scan on time”
1
has elapsed. Reading a label does
not disable scanning. Double Read Timeout
1
prevents unde-
sired multiple reads while in this mode.
Always On — The illuminator is always ON and the reader is
always ready for code reading. Double Read Timeout
1
pre-
vents undesired multiple reads.
Flashing — The reader illuminator flashes on and off regard-
less of the trigger status. Code reading takes place only
during the Flash On
2
time. Double Read Timeout
1
prevents
undesired multiple reads.
Object Detection — The scanner looks for changes within its
field-of-view. The Aiming Pattern is always on to show the
optimum reading area. If a predefined amount of movement
is detected, the red illumination switches on. Scanning con-
tinues until a label is read or "maximum scan on time" is
reached.
