Classification: CPC H | IPC H

Claim 13:
14. An industrial wireless remote control 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 in a broadcast mode for initiating a learning interchange during which each of the OCU and MCU securely exchange their unique Public MAC addresses with each other to thereby associate the OCU with the MCU whereby the OCU is operable for wirelessly transmitting commands to the associated MCU for wireless remote controlling operation of a machine, and whereby the MCU is only responsive to operator control units that are associated with the MCU;
wherein the OCU is configured to allow a user to input a user request to trigger and initiate the learning interchange during which each of the OCU and MCU securely exchange their unique Public MAC addresses with each other to thereby associate the OCU with the MCU.
