Classification: CPC H | IPC H

Claim 22:
23. A system comprising:
a machine control unit (MCU) having a unique public media access control address (Public MAC address); and
an operator control unit (OCU) having a unique Public MAC address different than the unique Public MAC address of the MCU;
the MCU and OCU each having a same private media access control address (Shared Private MAC address);, wherein:
the system is configured such that the Shared Private MAC address is usable for initiating a learning interchange during which the OCU and MCU exchange their unique Public MAC addresses with each other to thereby associate the OCU with the MCU whereby the OCU is operable for transmitting commands to the associated MCU for controlling operation of a machine;
the OCU includes a switch to allow a user to initiate the learning interchange during which the OCU and MCU exchange their unique Public MAC addresses to thereby associate the OCU with the MCU;
the MCU includes a switch to allow a user to prioritize the MCU for association with the OCU; and
the system is configured to:
associate the OCU with the MCU when the switch of the OCU and the switch of the MCU have both been activated; or
associate the OCU to an MCU having a highest received signal strength when the switch of the OCU is activated but the switch of the MCU is not activated.
