WherePort III User Guide D948 Rev B

Figure 17 Mode 2

More than one WherePort may be active at a time. A master and

three slaves are shown. One and three are active while 2 and 4

are inactive. WhereWand WPSeq Count (or RS232 CMWn) = 1.

Figure 18 Mode 3

All WherePorts 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, WherePorts 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.

3.6 Dual WherePorts

The dual WherePort is a bracket with two WherePorts mounted to it, oriented 90º from

each other (Figure 19). They ensure a guaranteed capture range and eliminate the need

for multiple mounting sites. Typically the dual WherePort 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 (see Figure 20). Dual WherePorts are

always phased with one set as the master at 0º and the other at 90º.
