Appendix
Host interface
Logical main data interface of the bar code scanner with two independent, configurable
data output formats. Allows, among other functions, the output of the reading result in tel-
egram form to the host/PLC. Physically switchable to RS-232/RS-422/485 and Ethernet
(port 2112) or CAN. Works as a gateway in conjunction with the SICK-specific CAN-SENSOR
network. Provides various transfer protocols (except for CAN).
With the Host interface, access to the bar code scanner for configuration and diagnosis is
always possible with the SOPAS-ET configuration software. The data transfer rate is 57.6
kbd in the default setting. The data output via RS-232/RS-422/485 can be switched off,
existing Host interface data output via Ethernet remains active. However, it can be eliminat-
ed separately.
Line scanner
Scanner that uses a polygon mirror wheel with paraxial mirrors to deflect a focused laser
beam extremely fast. As a result, it creates a light spot in the reading plane that moves along
a straight line, which appears to the naked eye as a stationary scan line.
Master/Slave configuration
Special arrangement and technical circuit connection of several bar code scanners to one
reading station (e.g. multi-side reading) using the CAN interface. Via the master the combi-
nation acts on the host as just one device.
Multi-reading
Selectable number of readings which must each deliver internal results from one and the
same bar code before the bar code scanner generates the reading result.
No read
The defined evaluation condition(s) were not met during the last reading pulse in the read-
ing process.
No read format
Special, configurable output format for no reads in the data output string as a replacement
for the output formats of a reading with fulfilled evaluation conditions. In its default setting,
the bar code scanner displays the "NoRead" string as the no read format, framed by STX and
EXT.
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.
