CLV 41x Bar Code Scanner
10. 4 AutoSetup (code configuration)
The AutoSetup function allows you to set the application-specific parameters
automatically to read
•
a bar code (from a code type with a fixed code length)
•
at a fixed reading distance.
For this purpose, the PC with the user interface must not be connected .
During AutoSetup, the CLV automatically determines the code type, code length and
the optimum scanning rate in free-running mode for the bar code presented at the
maximum reading distance.
All other code types are disabled for further
evaluation
. The CLV writes the parameter values to the parameter set directly and
stores it permanently (EEPROM).
Since the CLV overwrites important code configuration parameters without requiring
confirmation from the user, we recommend that you upload the valid CLV parameter
set to the PC and store it as a configuration file (*.scl) using the S
AVE
AS
menu option
in the user interface before you change the CLV parameters.
AutoSetup can be started at any time in Reading mode by presenting profile bar
code no. 12 and triggering the corresponding reading pulse. Alternatively, the CLV
can read profile bar code no. 12 in free-running mode directly after the device has
been switched and within the wait time of 5 seconds after the self-test has been
completed.
The CLV does not output any reading results during teach-in mode and does not
respond to an external reading pulse.
Note:
The CLV does not enter any real values for the Minimum Distance and Minimum Bar
Width parameters, since it cannot determine absolute dimensions. When you upload
the parameter set from the CLV to the PC, therefore, the values in the R
EADING
C
ONFIGURATION
card do not correspond to the actual values.
AutoSetup can also be called under the T
ERMINAL
menu of the user interface by
choosing the corresponding entry in the V
IEW
menu. The CLV, however, does not
output any reading results here. By connecting the PC, you can also subsequently
check the read quality of the bar code that was read in by switching to P
ERCENTAGE
E
VALUATION
mode.
