    The eight switches in group SW1 are used to set the node ID.
    Each node attached to the network must have an unique node ID which
    must be different from 0.
    Switch 8 serves as the least significant bit (LSB).

    -The node ID is the sum of the values of all switches set to "1"
    -These values are:
