5.2 Software Control
You can control the scanner by sending scanning control commands from the host computer via the Bluetooth
interface, instead of pressing the trigger switch.
Scanning control commands include R, READON, LON, Z, READOFF and LOFF and are restricted by the trigger
switch operating modes, as listed below.
Commands
Ready-to-scan commands
R,
Upon receipt of one of these
READON,
commands, the scanner lights
LON
the illumination LEDs and
becomes ready to scan.
Standby commands
Z,
Upon receipt of one of these
READOFF,
commands, the scanner turns
off the illumination LEDs and
LOFF
switches to standby.
Each of these commands should be enclosed with a header and terminator for transmission according to the
communications conditions of the scanner.
5.3 Auto Sensing Mode--Automatic detection of labels
After establishing the Bluetooth
Auto Sensing mode (Auto sense operation in Auto stand mode is included), bringing a code label within the scan
range of the reading window turns on the illumination LEDs and starts the scanner reading the code. No trigger switch
operation is required. Use this mode when the scanner is stationary to a stand and a code label is moved.
The illumination LEDs come on when you bring a code label within the designated range or move a code label within
the same range. These LEDs turn off when a code label is moved away from the range or stays within the range
without move for approx. 3 seconds.
In the Auto stand mode, after establishing the Bluetooth
broken" parameter, the scanner is set to the Auto sense operation when the power is turned on.
If the trigger switch is pressed while the scanner is operating in this mode, the scanner goes to the Auto off and reads a
code whenever the trigger switch is pressed.
However, the scanner will automatically return to the Auto sense operation if the trigger switch is not pressed for
longer than a time specified for the scanner to return to the Auto sense.
The time for the scanner to return to the Auto sense operation from the Auto off operation can be selected with the
configuration software (ScannerSetting_2D).
Auto sensing mode and Auto stand mode are selected with the QR-coded parameter menu or the configuration software
(Scanner Setting_2D).
The scanner offers a choice of three sensitivity levels for responding to codes. Switch to a higher sensitivity level if
the illumination LEDs will not come on when a code is brought into the range, for example.
Note: Even if you do not bring a code label within the scan range, the illumination LEDs may come on when the ambient
level of light changes or any shadows move within the scan range.
Note: To enable the scanner to work properly in auto sensing mode, an ambient illuminance of at least 500 lx is required.
