Online help – CLV Setup Help.
Adjusting mode
Special operating mode that enables the center of the scan line to be positioned exactly on
the object containing the bar code.
Aperture angle
α
Angle within whose limits the laser beam is deflected by the polygon mirror wheel.
A V-shaped range perpendicular to the scan direction, which must contain the bar code, is
formed in front of the reading window. If only part of this aperture angle is used (part of the
scan line symmetric around the center point), the depth of field for the focus position and
resolution is greater.
Aspect ratio
Ratio of the code height (bar length) to the code length (number of characters).
AutoSetup
Function that allows the code and reading configuration of the CLV to be adapted
automatically to the application at hand. The CLV searches for a bar code that is presented
at a fixed distance and the optimum scan rate. It enters the code type and code length and
disables all other code types and lengths.
Auxiliary input
Special function on the
terminal interface. Used to enter bar code data subsequently in
order to complete reading results sent to the host.
CLV Assistant
The Assistant simplifies parameterization and testing of the CLV, among other things. It
carries out configuration of the CLV for a user-specific reading situation with
one
bar code
in simple steps. The determined settings are transferred to CLV Setup.
CLV Setup
PC program which runs under Windows 95
TM
/98
TM
, Windows NT
TM
, Windows 2000
TM
and
Windows XP
TM
. Used for offline parameterizing (adjustment to the reading application at
hand) and the online operation of the CLV. The parameter set is exchanged with the CLV
by
uploading and downloading it.
CLV Setup Help
Online help function that provides support for using the "CLV Setup" program. The help
function contains explanations of the CLV parameters and their valid entries. Can be
launched directly from CLV Setup in an HTML browser such as "Internet Explorer
TM
".
Code geometry
Length and height dimensions of the bar code.
Code Info/Separator
Data block in the reading result of the
host interface. Used to add useful data to each bar
code. Can be attached to the bar code as a prefix or suffix. Contains up to 10 elements,
