3.2.6 Expanded Features
Power ON with Trigger Key
If the Trigger key has been set to “Enable turning on the power with Trigger key”, the power can
be turned ON (while the power was being turned off) when it is pressed down. This function
allows the user to achieve three-step operation with only one action, (1) turn on the power → (2)
press the Trigger key → (3) scan a bar code. This feature is a perfect idea when the user wishes to
resume scanning after the power has been turned off. The default is “Disable turning on the power
with Trigger key”.
Setting Trigger Key
4-way cursor key and side trigger keys can be set as the Trigger key. The default is only both left
and right side keys are set as the Trigger key.
Noise Filter
If the background of a bar code is white color, a noise tends to be generated easily during
scanning causing the error rate to increase. To reduce such the noise, the noise filter function is
available with the terminal. Two methods are available to set the function operable.

Software
noise filter
A software process removes noise. In determining the
blank at the leading edge of the bar code, if there is a
bar width smaller than a certain value, it will be
bonded to the fore and aft data, the noise eliminated
and the determination made. Also, the time from scan
start to “enable” of software filter can be set in the
range of 1 to 8 seconds. The default is 3 seconds.
Effective when
scanning leading
edge blank of bar
code using laser
module noted for
easily picking up
noise.
If initial bar is
extremely thin, it
will be determined
as noise and
eliminated, which
may mean that the
bar code cannot be
scanned.
Hardware
noise filter
A noise is removed with the laser module process by
narrowing the frequency band width of detecting bars
of a bar code symbol. This process makes a noise to
be generated less.
Effective for bar
code symbol with
poor resolution.
Not recommended
for bar code symbol
with high resolution.
Note:
The software noise filter is not effect with the DT-X11 series.
Configuration File
The various setting parameters related to scanning bar code symbols can be stored in a file
(configuration file) and then resumed. The configuration file storage path and its file name are
“\FlashDisk\System Settings\OBRDRV.ini”. If there is no such the configuration file existed, the
default values are used to initiate scanning.
