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 auxiliary interface. Used to enter bar code data subsequently in
order to complete reading results sent to the host.
Auxiliary interface
Auxiliary data interface (RS 232) on the CLX with fixed data output format. Used to connect
the "CLV-Setup" program to the CLX so that it can operate and configure the device. Also
used to output
Ö
system and error messages. Can be assigned various functions.
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
reading angle comparison functions. Enables bar codes with identical contents and code
type to be separated.

and is used to parameterize the CLX offline (adjust the device to the local condi-
tions) and operate it online. The parameter set is exchanged with the CLX by
Ö
uploading
and

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 Internet Explorer

Code geometry
Length and height dimensions of the bar code.
Code Info/Separator
Data block in the reading result on the
Ö
host interface. Used to provide additional informa-
tion about the bar codes. Can be attached to the bar code as a prefix or suffix. Contains up
to 10 elements, consisting of reading diagnosis data and/or constants (control characters,
