Communication Link with RPC2

When power is cycled to the MPH2, it takes a few moments to establish communication and load the
configuration information from RPC2, such as receptacle labels and IP and MAC addresses.

When configuration changes (such as turning-on/off a receptacle) require that the LCD screen update, the
configuration wheel appears and spins,

Figure 3-3

, to indicate that navigation is unavailable while

configuration is in-progress.
