Appendix
CLV-Setup Help
On-line help function that provides support for using the CLV-Setup program. The functions
of the parameters of the CLV are explained and the respective range of values specified in
the help. Runs under an HTML browser such as "Netscape Navigator
TM
" or the enclosed
"I-ViewPro
TM
" and can be called in CLV-Setup.
CLV-setup user interface
Windows-based input interface in the "CLV-Setup" PC software for operating and configuring
the CLV.
Code angle (CA value)
Current deflection range of the scan line (oscillating mirror) perpendicular to the scan direc-
tion when a bar code is detected. Is determined by the CLV for each scan and used, for ex-
ample, to define a capture range so that bar codes with identical data contents in a given
range can be separated.
Code geometry
Length and height dimensions of the bar code.
Code position (CP value)
Position of the first dark bar in a detected bar code along the
Ö
scan line. Determined by
the CLV for each scan and can be used, for example, to separate bar codes with identical
data contents. The active evaluation range in the scan line can be restricted for
Ö
decoding
purposes by specifying the maximum and minimum CP value for the application.
Command strings, commands
Alternative user interface to the CLV instead of the "CLV-Setup" program. Basic, yet clearly
structured command language for modifying the CLV parameter record online. Accesses the
CLV command interpreter directly. Special programming activities are required to use the
command strings from the host.
Configuration file
File in the CLV-Setup program that archives an entire
Ö
parameter record of the CLV. Can
also be printed out in tabular form.
Data forwarding
Option of forwarding data sent by the host transparently to a terminal via the CLV using an
identifier. The direction can also be reversed. Furthermore, this function also allows data re-
ceived on one of the serial interfaces to be output again straight away on one of the same
interfaces (echo). Application: Forwarding reading results or reading trigger commands in
pass-through mode, e. g. in a master/slave network.
Data output string
Structured data message of the
Ö
reading result output by the CLV on the
Ö
host interface.
The structure of the data string is flexible and can be adapted to a large extent to the sub-
sequent data processing task. The data output format of the
Ö
terminal interface, on the
other hand, cannot be changed.
