5.6.5 Safety Time
Safety time prevents the device from immediately decoding the same code more than
once. Same code consecutive reading can be disabled requiring the reader to be
removed from the code (no decoding) for at least 400 ms, or a timeout can be set up
to 9.9 seconds before the decoder will accept the same code. Reading is immediate if
the code changes.
The safety time parameter is not applicable when reading stacked codes or when
setting one read per cycle in hardware trigger operating mode, since these settings
require voluntary action by the user.
5.7 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.
5.7.1 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.
5.7.2 Overflow Control
The overflow control parameter can be disabled when decoding codes printed on
small surfaces, which do not allow the use of an overflow space.
This command does not effect code families 2/5, Code 128 and Code 93.
This command is forced (enabled) when PDF417 codes are enabled.
5.7.3 Interdigit Control
The interdigit control parameter verifies the interdigit spacing for code families Code
39 and Codabar.
