Operation
Note
The CLV only outputs several bar codes in the reading result if the parameterized minimum
and maximum number of bar codes is > 1, and several bar codes have been presented to
it. The number of bar codes to be read/output for each reading interval can be selected in
the C
ODE
C
ONFIGURATION
tab in the N

section.
The reading result of the
host interface
can also be displayed.
