3.4 Phases
When two are more WherePorts are used to cover a large area they must be phased to
reduce the interference between the two fields. WherePorts mounted on the ceiling might
be set to 0º and on a wall 90º. Figure 15 shows the correct phase settings for four
orientations of the WherePort. The phases are set with reference to the orientation of the
master WherePort.
A WherePort set to 0º phase is defined as the master and all the other WherePorts
are then connected to it using the phase wire connections. Phased WherePorts must all
have the same ID.
