• a receiver for receiving messages from the first and second subnet on the predetermined RF;
• an Input/Output device for receiving or sending information;
• and
• a processor, wherein said processor is operatively connected to said memory, transmitter, receiver, display device and Input/Output device, and wherein said processor transmits a link claim to the first and second subnets, a first command and random wait time to the first subnet, and a maximum random wait time to the second subnet by way of said transmitter, and receives an acknowledgement from the first subnet by way of said receiver.
