5.4 Power Save

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).
