Scan modes

The scanner can operate in one of several scanning modes.
Trigger Single: When the trigger is pulled, scanning begins until one of the following occurs:
A programmable duration has elapsed
A label has been read
The trigger is released
"Maximum scan on time" is reached
This mode is associated with typical handheld scanner operation.
Trigger Hold Multiple: When the trigger is pulled, scanning begins and the product scans until the trigger is
released, a programmable duration has elapsed, or the "maximum scan on time" is reached. Reading a label
does not disable scanning. "Double read" time-out prevents undesired multiple reads while in this mode.
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 "maximum scan on time" is reached or a programmable duration
has elapsed. Reading a label does not disable scanning. "Double read" time-out prevents undesired multiple
reads.
Flashing: The reader flashes on and off regardless of the trigger status. Code reading takes place only during
the flash on time. "Double read" time-out prevents undesired multiple reads.
Always On: The illuminator is always on regardless of the trigger status and the reader is always ready for
code reading. "Double read" time-out prevents undesired multiple reads.
Object Detection: In this mode the scanner looks for scene changes within its field of view to initiate read
attempts. To help the user find the position of the reading line, the green spot can be configured to be on.
When an object's presence is detected in the scene, the illuminator turns on and turns off the green spot.
Scanning continues until the Object Gone Timeout expires after last read. "Double read" time-out prevents
undesired multiple reads while the scanner is in this mode.
Trigger Object Sense: This is similar to Object Detection. A trigger pull is required to activate the decoder.
NOTE:
See the Product Reference Guide (PRG) for more information.
