Abstract
PURPOSE:To connect two devices without remodeling hardware even in case of a difference in parity between two devices by controlling parity setting for generation of parity and that for detection of parity in a channel controller by a main processor. CONSTITUTION:Parity setting for generation of parity to data inputted to a computer of one device, that for detection of parity to data outputted from this computer, that for generation of parity to data outputted to the other device, and that for detection of parity to data inputted from the other device are performed in the channel controller, and a parity control circuit 6 is provided which controls respective parity settings independently of one another by the indication of a main processor 1. Since parity setting for generation of parity and parity setting for detection of parity which are performed in a channel controller 5 are controlled by the main processor 1, data is transmitted between devices different in parity from each other without remodeling hardware.
