Connecting Shelves
For a 3- or 4-shelf system, you need to install an optional BUS-M card and BUS-ME card(s) in the Basic Shelf.
To connect the shelves, plug the Bus Cables (supplied with the BUS-M card or BUS-ME card) into the slots
of the BUS-M card. Then, plug the other end of each Bus Cable into the BUS-S card built in to each Expansion
Shelf.
For details about the cards, refer to "2.4.1 BUS-M Card (KX-TDA6110)", "2.4.2 BUS-ME Card
(KX-TDA6111)", and "2.5.1 BUS-S Card".
Note
