Scanning Features
Scan Mode
This mode is associated with typical handheld reader operation. Selects the
scan operating mode for the reader. The following selections are valid for all
models:
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
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 acti-
vated until Scanning Active Time has elapsed or the trigger has been
released and pulled again. Double Read Timeout prevents undesired multi-
ple reads of the same label while in this mode.
Flashing:
The reader flashes 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 bar code. Scanning is contin-
ually on. If the trigger is pulled, the reader acts as if it is in Trigger Single
Mode. Double Read Timeout prevents undesired multiple reads of the same
label while in this mode.
Stand Mode:
No trigger pull is required to read a bar code. 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 prevents undesired multiple reads while in this mode.
