Scan Modes
The imager can operate in one of several scanning modes:
Trigger Single — When the trigger is pulled, scanning is activat-
ed 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 opera-
tion.
Trigger Hold Multiple — When the trigger is pulled, scanning
starts and the product scans until the trigger is released or a
programmable duration
1
has elapsed. Reading a label does not
disable scanning. Double Read Timeout
1
prevents undesired
multiple reads while in this mode.
Trigger Pulse Multiple — When the trigger is pulled and re-
leased, scanning is activated until programmable duration1
has elapsed or the trigger has been pulled again to transition to
another state. Double Read Timeout
1
prevents undesired
multiple reads while in this mode.
Flashing — The reader flashes
1
on and off regardless of the trig-
ger status.
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 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
reader’s field of view. If the trigger is pulled, the reader acts as
if it is in Single Read
mode. Double Read Timeout
1
prevents
undesired multiple reads while in this mode.
