2.6 REDUNDANCY SCANNER CONNECTIONS
Reliability and robustness of the system can be improved by connecting scanners together in a
particular way. In case of failure for the redundancy cable, which connects the two PWOs together,
the active device only sees the scanners physically attached to the relative PWO. In this case, the
best result will be achieved if the scanners in question read as much as possible over the entire
reading area. A possible solution to fulfill this is to connect scanners alternatively.
