• the slave device and the control master unit are capable of communicating wirelessly with each other;
• the control master unit is configured to:
• transmit, to the slave device, a wireless command signal containing a command instruction;
• the slave device is configured to:
• write the command instruction to the slave device memory to create a stored instruction;
• read the stored instruction from the slave device memory;
• and
• transmit, to the control master unit, a wireless response signal containing the stored instruction;
• the control master unit is further configured to:
• compare the stored instruction to the command instruction;
• and,
• only if the stored instruction is the same as the command instruction, send a process instruction to the slave device.
