4.2.10 Enter Sleep Timeout
For readers that have the Sleep state enabled, this timeout determines when the reader
will enter this state.
4.2.11 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.
Standby is always enabled and is not configurable. To exit Standby press the trigger.
4.3 READING PARAMETERS
4.3.1 Hardware Trigger Mode
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
4.3.2 Trigger-Off Timeout
When this timeout is selected, the reader turns OFF automatically after the desired period
of time.
4.3.3 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. 4.3.2).
When one read per cycle is selected, the device decodes only one code during the ON
period and immediately turns the reader OFF. It is only possible to read another code when
the next ON time occurs.
In multiple reads per cycle , the ON period is extended so that the device can continue
decoding codes until an OFF event occurs. For software trigger mode, the flash on period is
immediately reset after each read and therefore extended. If another code is decoded
