5.5.1

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. 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 section 5.5.2)

To exit Sleep mode press the trigger.

For M8300 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.

5.5.2
