For further terms, please refer to the online help
"CLV-Setup Help".
Aspect ratio
Ratio code height (bar length) to code length (numer of characters). Using the SMART De-
coder even bar codes with very small code height can be read.
Autofocus function
Ability of the CLX to detect the distance of the objects during the reading operation without
external sensors in order to adapt the focus position to the reading plane of the bar codes.
Auxiliary input
Special function on
Ö
the terminal interface. Used to enter bar code data subsequently in
order to complete reading results sent to the host.
CAN interface
Can be used for building a quick SICK specific CAN Scanner Network with several functions
(e.g. multiplex function, master/slave configuration) or for the integration into an existing
CAN network according to the CANopen protocol.
Capture range
Zone around a moving bar code created by the CLX using the increment management and
code position comparison functions. Enables bar codes with identical contents and code
type to be separated.
CLV-Setup
PC program that runs on Windows 95
TM
/98
TM
, Windows NT
TM
and Windows XP
TM
is used to
parameterize the CLX offline (adjust the device to the local conditions) and operate it online.
The parameter set is exchanged with the CLX by
Ö
uploading and
Ö
downloading it.
CLV-Setup Help
Online help function that provides support for using the "CLV-Setup" program. The help
function explains the CLX parameters and their permissible values and can be launched
directly from CLV-Setup in an HTML browser, such as Netscape Navigator
TM
, or I-ViewPro
TM
supplied with the program.
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. Calculated by
the CLX for each scan and can be used, for example, to separate bar codes with identical
data contents.
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.
