//  To configure FDRS:
 
//   Each device in the system has a unique, one-byte address which 
//    is assigned to the last digit of its MAC address at startup.

//   Each relay receives data from its pre-programmed "PREV_MAC" device and
//    sends the packet verbatim to the address corresponding to "NEXT_MAC".

//   The gateway receives the data and outputs it as a json string over the serial port.
