In a daisy chain connection system in which a plurality of card devices are installed in each slot of a backplane that forms a daisy chain using a bus permit line or an interrupt response line in an input/output bus, a daisy chain is installed in each slot. A three-way connection between the chain input side and the daisy chain output side.
A state buffer is connected, and the card device is provided with a signal transmitting means for disabling the three-state buffer, and when the card device is not installed, the three-state buffer is enabled and passes through the daisy chain signal. and wherein when the card device is installed in the slot, the three-state buffer is disabled and the daisy chain signal is transmitted into the card.
