The control unit has allocated each expander a block of zone numbers, up to the capacity
of the device. Note the link between zone number and connection point address. The last
digit of the connection point address is the same as the last digit of the zone number. The
middle digits of the connection point address (the bus device number - underlined) are the
same as the first two digits of the zone number (underlined).
