Abstract
PURPOSE: To eliminate the limitation for the driver capacity in case the physical gap is increased between the units by actuating the receiver circuit as well as the driver of the interface part by the 2nd unit and via the power voltage supplied from the 1st unit.
CONSTITUTION: The 1st unit supplies power voltage 31 to the 2nd unit along with the signals, and the 2nd unit amplifies the signals given from the 1st unit to then transfer them to the lower-rank unit. At the same time, the 2nd unit repeats once the signals to be given to the 1st unit and then transfer them to the 1st unit. In this system, the 1st unit supports the power capacity of the circuits for driver 35, 43, 44, 37, 39 and 41 plus receiver 34, 42, 36 and 40 each at the interface part of the 2nd unit, and does not support the power capacity of the entire 2nd unit. Accordingly, a comparatively small amount of power capacity suffices for the 1st unit itself. This system is not applied to all 2nd units but applied in terms of the key, and thus the cable length can be increased between the units.
