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 don’t 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.
5.8 RADIO PARAMETERS (M SERIES ONLY)
5.8.1 Radio Protocol Timeout
This parameter sets the valid time to wait before transmission between the M series
reader and OM-DRAGON cradle is considered failed.
This parameter should be set taking into consideration the radio traffic (number of
readers in the same area).
If the RS232 interface is used with ACK/NACK enabled, this parameter should be at
least equal to the Rx Timeout parameter for low traffic environments. It should be
increased if there are many readers in the same area.
It can be set between 2 and 19 seconds.
