Function of the tabs in CLV-Setup (overview)
Reading Configuration
This tab and further dialog boxes are used to set the following:
•
Scanning frequency
•
Start/stop ratio
•
Reading area (reading angle limits or three-dimensional reading space when the
conveyor is running)
•
Autofocus mode (object distance measurement, preference focus distance, delay of
focus change, depth of field optimization, autofocus space, delimitations, extent of
deflection)
•
Reading distance configurations for event-controlled focus control (focus position,
evaluation range of the scan line, assignment table)
•
Trigger source for the focus control
•
Adjustment to bar code quality caracteristics, background (scattered print) and relative
module width
Device Configuration
This tab and further dialog boxes are used to set the following:
•
Device number
•
Source of the Reading trigger mode
•
Laser timeout
•
Output time of the Reading result referred to the start of the reading interval
•
Scanner position parameters (the position of the CLV490 in the area)
•
Tracking parameters
•
Object polling parameters
•
Output filter of the reading result (host interface)
•
Physical arrangement for data output via the host interface
(stand-alone, master/slave)
•
Functional assignment of the "IN 3" and "IN 4" switching inputs
•
Functional assignments of the "Result 1" to "Result 4" switching outputs
•
Start option for accessing the parameter set
•
Match code
Code Configuration
This tab and further dialog boxes are used to set the following:
•
Type of active decoder (SMART and/or standard decoder)
•
Evaluation routines for individual code types
•
Number of identical reads (multiple reads)
•
Minimum and maximum number of bar codes to be read/output
•
Start/Stop recognition mode
•
Activation of the comparison of the reading angle for the separation of identical bar
codes
•
Special parameters of the SMART decoder (e. g. for OTS mode)
Recommendation
To enhance the reading reliability with fast applications, only activate those code types and
code lengths that are actually relevant.
