CLV63x Bar Code Scanner
Appendix
Parameter value set
Data set which is used to initialise and activate the implemented functions of the bar code
scanner. Transferred using the upload (all parameter values only) or download from the bar
code scanner SOPAS-ET configuration software or vice versa.
Raster scanner
Scanner that uses a polygon mirror wheel with tilted mirrors to deflect its focused laser
beam extremely quickly. As a result, it creates a light spot that moves quickly in several rows
across the reading plane. Each light spot repeatedly moves along a straight line. It thereby
appears to human eyes as one of several stationary scan lines.
Reading angle (RA value)
The reading angle from the reading window to the red scanning line of the scanning beam
under which the middle of a bar code is detected. Recorded by the bar code scanner for
each scan and used, e. g., for the separation of bar codes with identical data contents. For
the decoding process, the active analysis area along the scanning line can be restricted application-
specifically by presetting the minimum and maximum RA values.
Reading diagnosis data
Code-, object- or device-related data which the bar code scanner derives directly from the
reading process. The data allows, among other things, an assessment of the reading quality
and to draw conclusions on the reading process.
Reading gate, reading interval
Time window in which the bar code scanner switches on the scanning line and attempts to
recognise valid bar codes from the read information. The reading gate can be shorter than
the external reading pulse, depending on the output mode of the selected reading result.
Reading pulse
Triggering of the internal reading gate via a bar code scanner-external pulse is carried out
by means of an external trigger source such as a photoelectric reflex switch or a command
string via the data interface. With internal trigger source "automatic tick", the bar code scanner
creates the reading pulse itself.
Reading range (DOF)
Depth of field at both sides of the lens focal point at the reading level. The size of the range
depends on resolution and reading distance.
Reading result
Electronic display and output of the data contents of the scanned bar codes together with
reading diagnosis data in a data output string at the defined output time.
