Abstract:
1. A computer capable of being connected to an IO expansion device for connecting at least one external IO device to the computer, the computer comprising: an IO unit including a first connection interface for connecting the IO expansion device, sending an output signal to the external IO device connected to the IO expansion device and receiving an input signal from the external IO device; and a monitoring and control unit including wherein the monitoring and control unit compares the connection setting information stored in the storage and the connection setting information acquired from the IO expansion device through the second connection interface, and determines that the IO expansion device is correctly connected to the IO unit when the connection setting information acquired from the IO expansion device and the connection setting information stored in the storage match each other, and that communication between the IO expansion device and the IO unit is disabled when the connection setting information acquired from the IO expansion device and the connection setting information stored in the storage do not match each other.
