    receiving said signal by a plurality of receiving modules, the receiving modules comprising at least some of the electronic display modules;

    decoding the address part of said signal by each receiving module into a received address;

    comparing the received address to the module address for each receiving module;

    matching the received address to the module address in at least one addressed module among the receiving modules;

    for each addressed module, decoding the data part of the signal into product information;

    storing the decoding product information in a memory of the addressed module; and
