Distance detection
Device detecting in 2 graduation distances from objects carrying the bar codes. One examp-
le is the downward reading of a photoelectric reflex switch arranged beside the conveyor
system. The ranges for focus position switching are defined through combinations of the
switched input "Sensor 1" and the cross-reference list for distance configurations.
Distance configuration
Data set in the bar code scanner to establish a focus position of the laser beam for focus
position switching. The depths of field for the individual focus positions can be obtained
from the specification diagram in relation to the resolution.
Aspect ratio
For bar codes with the code height (strip length) to code length (number of characters) ratio.
Deflection range
Deflection of the scanning line by way of the oscillating mirror across the scanning direction
to both sides of the central position CW=50 (corresponds to a light exit under 105° (default
setting)). Also called oscillation amplitude.
Deflection angle
Angle which the scanning line covers at both sides each of the central position CW=50 (cor-
responds to 0°) when deflected by the oscillating mirror. Also called oscillation angle.
Autofocus function
Ability of the CLV65x to detect the distance of the objects without external sensors in order
to adapt the focus position to the object distance.
Aux interface
Logical auxiliary data interface of the bar code scanner with a fixed data output format, phy-
sically switched to RS-232 (Aux) and Ethernet (port 2111). With this data interface, access
to the bar code scanner for the configuration is always possible with the PC and the SO-
PASET configuration software. The data interface is also used for diagnosis (output of rea-
ding diagnosis data or monitoring the data traffic on the Host interface). For the physical RS-
232 interface, the following applies: fixed data format, data transfer rate 57.6 kbd. The data
output to the PC via RS-232 can be switched off, existing Aux interface communication via
the Ethernet interface (port 2111) remains active.
