Figure 57 Mode 3
All WherePort IVs may be off part of the time. A master and one slave are shown. One is active, then
two, then both are inactive. WhereWand WPSeq Count (or RS232 CMWn) = 2 or higher.
With sequencing, WherePort IVs that might have conflicting fields if they were on at the same time, can
be placed to indicate position or transitions. An example is narrow parking lanes in a warehouse facility.
7.7. Dual WherePort IVs
The dual WherePort IV is a bracket with two WherePort IVs mounted to it, oriented 90º from each other
(Figure 68). They ensure a guaranteed capture range and eliminate the need for multiple mounting sites.
Typically the dual WherePort IV is used when the orientation of the tag can not be fixed. They also
simplify placement in locations that are larger than the guaranteed capture range of a single WherePort
IV (see Figure19). Dual WherePort IVs are always phased with one set as the master at 0º and the other
at 90º.
