NOTE
Since Test Mode is basically a diagnostic mode, it can
only
be
enabled at run time and not saved to a non-volatile memory.
For the same reason, this operating mode must be disabled
only
via RS232 interface by selecting another Operating Mode
command, if you want to restore the previous state of the
reader.
5.5.2
Reads per Cycle
In general, a
reading cycle
corresponds to the Phase ON / Phase 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 Phase ON and Phase OFF times.
When
one read per cycle
is selected, the device decodes only one code during the
Phase ON period and immediately turns to the Phase OFF. It is only possible to read
another code when the next Phase ON time occurs.
In
multiple reads per cycle
, the Phase ON period is extended so that the device
can continue decoding codes until an OFF event occurs.
5.6 DECODING
PARAMETERS
CAUTION
These parameters are intended to enhance the decoding capability
of the reader for particular applications. Used incorrectly, they can
degrade the reading performance or increase the possibility of a
decoding error.
5.6.1 Ink-Spread
The ink-spread parameter allows the decoding of codes which are not perfectly
printed because the page texture tends to absorb the ink.
