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.
