4.4 POWER SAVE
4.4.1 Illuminator/Laser Driver
To reduce maximum power consumption, this command assures that the
Illuminator (for CCD devices), and the beeper are not on simultaneously.
For scanners the Laser and the beeper are not on simultaneously.
4.4.2 Sleep State (only devices with button/trigger)
This mode allows the
µP in the reader to enter a “Sleep” state for minimum power
consumption. 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.4.4.3)
To exit Sleep mode press the trigger.
Enabling the Sleep state implements Standby mode for CCD devices, see par. 4.4.4,
and disables FIFO, see par. 4.1.3.
4.4.3 Enter Sleep Timeout
For readers that have the Sleep state enabled, this timeout determines when the
reader will enter this state.
4.4.4 Standby (only CCD devices with button/trigger)
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.
Disabling Standby automatically disables Sleep State, see par. 4.4.2.
