Operation
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 CLV 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 ... Result 4" switching outputs
•
Start option for accessing the parameter set
•
Code position comparison
Code Configuration
This tab and further dialog boxes are used to set the following:
•
Type of active decoder (SMART 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
•
Kind of Start/Stop recognition
•
Activation of the comparison of the code position for the separation of identical bar co-
des
Recommendation
To enhance the reading reliability with fast applications, only activate those code types
and code lengths that are actually relevant.
Host Interface
This tab and further dialog boxes are used to set the following:
•
Destination of the read result date strings (host interface or CAN interface)
•
Active physical interface (RS 422/485 or RS 232)
•
Data format and transmission rate
•
Data transmission protocol
•
Start and stop characters of the interface protocol
Data Strings
This tab and further dialog boxes are used to set the following:
•
Data output format of the host interface (telegram format)
•
Constants and reading diagnosis data in the header, separator and terminator
•
Arrangement of the separators in the data string
•
Output format for no reads and contents of the error string
•
Test string function
•
Output sequence and sort criteria for reading more than one bar code per reading pulse
•
Format mask and its structure
