Start/Stop operation
In this reading operation mode, only one object per reading pulse is located in the reading
area. Two external sensors or command strings control the beginning and end of the rea-
ding pulse for the bar code scanner (stand-alone device). The length of the reading area is
determined in this case by the distance of both reading pulse sensors for the start (begin-
ning of the reading area) and stop (end of the reading area). The minimum reading distance
between two objects must always be greater than the length of the reading area.
In the case of combined use with other bar code scanners in a master/slave combination
(e.g. unidirectional double-side reading), the bar code scanner as a slave receives its pulse
signals from another bar code scanner (master). The bar code scanners are networked via
the CAN interface, the output of the master’s reading result via its RS- 232/RS-422/485
interface and/or the Ethernet interface.
Pine tree effect
This effect of the line scanner with oscillating mirror is a result of the limits set by the active
scan line range and the oscillation amplitude (CW value). Hence a "sharp window" of the
same size can be generated in the reading field for every distance configuration for any read
distance.
Teach-in
Method of programming the information required to adjust the CLV65x to the reading appli-
cation in Parameterization mode.
Example: teaching in the background for the Autofocus function, also known as a distance
profile.
Switching sequence
Sequence of the focus positions to be adjusted one after the other with the corresponding
depths of field. For this purpose, the numbering of the active distance configurations is
entered in the cross-reference list in the desired position.
Upload
Transfer process of all parameter values from the connected bar code scanner’s working
memory to a PC in the SOPAS-ET configuration software for display and modification. This
is achieved when the device is connected and communication is successfully carried out af-
ter the scanning process for a confirmed request to synchronise the user interface and the
bar code scanner. Where necessary, this can be triggered manually in the Kommunikation
menu (U
