Scanning Modes
The reader can operate in one of several scanning modes:
Trigger Single — When the trigger is pulled, scanning is activated
until one of the following occurs:
- a programmable duration
1
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
programmable duration
1
has elapsed.
Trigger Hold Multiple — When the trigger is pulled, scanning starts
and the product scans until the trigger is released or a program-
mable duration
1
has elapsed. Reading a label does not disable
scanning. Double Read Timeout
2
prevents undesired multiple
reads while in this mode.
Trigger Pulse Multiple — When the trigger is pulled and released,
scanning is activated until programmable duration
1
has elapsed
or the trigger has been pulled again to transition to another
state. Double Read Timeout
2
prevents undesired multiple reads
while in this mode.
Flashing — The reader flashes
3
on and off regardless of the trigger
status.
Always On — No trigger pull is required to read a bar code. Scan-
ning is continually on. Double Read Timeout
4
prevents unde-
sired multiple reads while in this mode.
Stand Mode — No trigger pull is required to read a bar code. Scan-
ning is turned on automatically when an item is placed in read-
er’s field of view. If the trigger is pulled, the reader acts as if it
in Trigger Single mode. Double Read Timeout
5
prevents un-
desired multiple reads while in this mode.
Trigger Object Sense — This mode is similar to Stand Mode, ex-
cept that a trigger pull is required to activate the decoder.
NOTE
If the interface type is changed, scanner configu-
ration may be automatically reset to a different
Scanning Mode.
