Appendix
Master/slave configuration
Special arrangement for connecting up to max. 10 CLX to one reading station (e. g. left/right
read) using the CAN interface. Thanks to the master, the entire network appears as one de-
vice to the host.
Multiple read
Variable number of reading operations that must provide identical reading results (data
content) of the same bar code before the CLX outputs the result.
No Read
The CLX failed to detect a bar code or the required number of bar codes specified by the
evaluation parameters during the
Ö
reading pulse.
No Read format
Special, parameterizable data block as a substitute for bar codes, which were expected but
not detected, in the data output string on the host interface for
Ö
No Read. Comprises a
variable combination of the error string and the
Ö
separator.
Object height detector
See distance detector.
Parameter set
Data record used to initialize and activate the functions implemented in the CLX. With down-
loading and uploading the parameter set is transferred form CLV-Setup to the CLX or from
the CLX to CLV-Setup.
Parameter memory, external
Optional accessory containing an integrated connector cover. Enables devices to be conve-
niently replaced by storing a copy of the CLX parameter set (EEPROM). The replacement de-
vice then accesses this parameter set directly and does not have to be configured manually.
Percentage evaluation
Special operating mode in which the quality of the reads (not those of the barcodes, how-
ever) is assessed statistically. The bar codes must be stationary. The CLX carries out 100
scans and evaluates the reading quality. It then outputs the reading results on the
Ö
termi-
nal interface every 2 s together with the reading diagnosis data.
Plain text
Legible form of a CLX message. The CLX outputs special messages in coded form, e. g. the
result of the self-test is represented as three digits.
Reading diagnosis data
Data directly derived from the reading procedure by the CLX. This data enables the quality
of the read to be assessed. The data is always output on the
Ö
terminal interface together
with the reading result. Only output on the host interface if enabled on the D
ATA
S
TRING
tab
in the CLV-Setup program. The error status ST is output in the separator by default.
Reading field height
Length of the
Ö
scan line that is available for detecting the bar code in the reading plane.
