Figure 4.9: Scanner Arrangement With The Multiscan Function - Leuze electronic BCL500i Technical Description

Device description
always process two readings for a single packet, i.e. a decoding result and a No Read, a
multiScan arrangement is used which transmits only one reading from the two read stations
to the host; this single reading is transmitted by the multiScan master.
Notice!
Thus, from the perspective of the host, the scanner network appears to be just a single bar-
code reader!
For this purpose one multiScan master and one or more multiScan slaves are connected
together via the RS 485 interface.

Notice!
The multiScan function on the RS 485 interface is possible for minimum of 2 and a maxi-
mum of 32 devices!
The protocol set on the RS 485 interface is the multiNet protocol. As a result, during multi-
Scan operation on the RS 485 interface, the multiNet master also functions as the
multiScan master and the multiNet slaves function as multiScan slaves (thus, all multiNet
slave are included in multiScan operation).
