A wireless communications system for viewing and modifying memory locations within a power system device is provided including a wireless device and a power system device. The wireless device includes an input mechanism adapted to accept input from a user indicating a memory location the user wishes to view; a first radio frequency transmitter for transmitting a first signal including the memory location within the power system device the user wishes to view; and a first radio frequency receiver for receiving a second signal. The power system device includes at least one randomly accessible memory location and a processor coupled to at least one randomly accessible memory location; a second radio frequency receiver coupled to the processor and a second radio frequency transmitter coupled to the processor for receiving the first signal. The processor retrieves the value of the memory location included within the first signal and activates the second radio frequency transmitter to transmit a second signal including the value of the memory location. The value of the memory location may be a command or control that is executed by the power system device.
