letters, digits), depending on the configuration. The "Code-Info/Separator" block is empty in
the default setting of the CLX.
Command strings, commands
CLX user interface – alternative to the "CLV-Setup" program. Basic, yet clearly structured
command language for modifying the CLX parameter sets online. Accesses the CLX
command interpreter directly. Special programming activities are required to use the
command strings from the host.
CLX490 Compact OMNI Scanner
Scanner with a scan line deflected by two mirrors in the device cover. The scan line is folded
and crossed which allows omnidirectional reading of bar codes.
Configuration file
File in the "CLV-Setup" program that archives the entire
Ö
parameter set of the CLX. Can
also be printed out in tabular form.
Data forwarding
Option of forwarding data sent by the host transparently to a terminal via the CLX using an
identifier. Data can also be forwarded in the opposite direction. Furthermore, this function
also allows data received on one of the serial interfaces to be output again straight away on
one of the same interfaces (echo).
Data output string
Structured data telegram in the
Ö
reading result output by the CLX 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
auxiliary interface, on the
other hand, cannot be changed.
Decoder, decoding
Code-type-specific evaluation routine for reconstructing the read bar code in electronic form
in order to decode its data content.
Distance configuration
Data record in the CLX for defining a
Ö
focus position for the laser beam for
Ö
dynamic
focus control. The focus position must be entered on the R

tab in the
"CLV-Setup" program for this purpose. The depths of field for the individual focus positions
are shown as a function of the resolution values in the specification diagrams.

Method of transferring the
Ö
parameter set that was modified with the
Ö
CLV-Setup pro-
gram offline from the PC to the CLX. CLV-Setup either always transfers a complete copy to
the memory (RAM) of the CLX (D
