 One RK611 can control up to 8 drives; a [[flat cable]] plugs into a [[Berg connector]] on one of the cards, and runs to a transition adapter on the back of the rack. From there, a round cable runs to the first drive, and similar cables connect the rest of the drives, in series. A [[terminator]] must be plugged into the 'out' port of the last drive in the series.
