Scanning Features
Scan Mode
Selects the scan operating mode for the reader. Selections are:
Trigger Single. When the trigger is pulled, scanning is activated until one of the following
occurs:
- Scanning Active Time has elapsed
- a label has been read
- the trigger is released
This mode is associated with typical handheld reader operation: when the trigger is pulled,
scanning starts and the product scans until the trigger is released, or a label is read, or the
maximum
Scanning Active Time has elapsed.
Trigger Hold Multiple . When the trigger is pulled, scanning starts and the product scans until
the trigger is released or Scanning Active Time has elapsed. Reading a label does not disable
scanning. Double Read Timeout prevents undesired multiple reads of the same label while in
this mode.
Trigger Pulse Multiple. When the trigger is pulled, continuous scanning is activated until
Scanning Active Time has elapsed or the trigger has been released and pulled again. Double
Read Timeout
1
prevents undesired multiple reads of the same label while in this mode.
Flashing. The reader flashes
1
on and off regardless of the trigger status. Flash rate is controlled
by Flash On Time and Flash Off Time . When Flash is ON the imager reads continuously; when
Flash is OFF scanning is deactivated.
Always On. No trigger pull is required to read a barcode. Scanning is continually on. If the
trigger is pulled, the reader acts as if it is in Trigger Single Mode. Double Read Timeout
1
prevents undesired multiple reads of the same label while in this mode.
Stand Mode. No trigger pull is required to read a barcode. Scanning is turned on automatically
when an item is placed in the reader’s field of view. If the trigger is pulled, the reader acts as if it
in single read mode.
Double Read Timeout
1
prevents undesired multiple reads while in this
mode.
Trigger Object Sense. This mode is similar to Stand Mode, except that a trigger pull is required
to activate the decoder.
