5.4 POWER SAVE
5.4.1 Sleep State/USB Suspend
When using interfaces other than USB, this mode allows the µP in the reader to enter
a “Sleep” state for minimum power consumption. For D-series readers, this command
is only valid when hardware trigger type is selected.
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.
Enabling the Sleep state implements Standby mode for CCD devices, see par. 5.4.3.
For Mx30 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.
5.4.3 Standby
If this command is enabled, part of the CCD circuitry shuts down (Standby), in order
to optimize low power consumption when not reading. When the trigger is pressed
this circuitry powers up. This mode causes a minor delay of about 100 ms before the
reader is ready.
For Mx30 series readers, standby is always enabled and is not configurable. To exit
Standby press the trigger.
