5.4.1 Sleep
State
When using interfaces other than USB, this mode allows the
P in the reader to enter a “Sleep” state for minimum power
consumption.
Before entering Sleep mode, the following are verified:
no commands coming from Host
no data being transmitted to Host
Enter Sleep Timeout ended (see par. 5.4.2)
To exit Sleep mode press the trigger.
For BT8300 series readers, sleep state is entered immediately after reading a code and is not configurable. To exit Sleep
mode press the trigger.
When using the USB interface, this mode allows the device to manage Selective Suspend conditions generated by the
Host Operating System in which optimizing low power consumption (ex. Windows Stand-by). It is possible to exit the
Suspend mode either from the Host (ex. moving the mouse during Stand-by) or through the barcode reader. The latter,
called Remote Wakeup, makes the device wake up the Host restoring the communication. Remote Wakeup is possible by
pressing the trigger.
5.4.2
Enter Sleep Timeout
For readers that have the Sleep state enabled, this timeout determines when the reader will enter this state.
5.5 Reading
Parameters
5.5.1 Trigger
Signal
This mode determines how the reading phase is controlled when the hardware trigger operating mode is selected:
trigger active level: the reader goes ON when the trigger is pressed and goes OFF when it is released
trigger active pulse: the reader goes ON at the first trigger press and goes OFF only at a second press
5.5.2 Trigger
Click
When enabled, it activates a "click" sound upon each trigger pressure.
5.5.3 Trigger-Off
Timeout
When this timeout is selected, the reader turns OFF automatically after the desired period of time.
5.5.4
Reads per Cycle
In general, a
reading cycle
corresponds to the ON + OFF times of a device.
The resulting effects of this parameter on code reading depend on other related configuration conditions. Here are the
definitions of ON and OFF times.
For readers using the software trigger parameter (FLASH MODE), a reading cycle corresponds to the
flash on
+
flash
off
times. Code reading takes place during the
flash on
time.
For readers using the
hardware trigger
parameter, a reading cycle corresponds to a trigger press (ON) + one of the
following OFF events:
trigger release (for
trigger active level
)
a second trigger press (for
trigger active pulse
)
trigger-off timeout
(see par. 5.5.3).
