Abstract: After powered on, a check unit rewrites a lookup table in a memory of a programmable logic circuit unit to one of lookup tables in its own memory so as to switch a circuit state that a logic circuit implements. When the check unit outputs an inquiry signal in this state and an identification signal which responds to the inquiry signal is input into the check unit from a check circuit of a sub substrate via the logic circuit and a port, the sub substrate corresponding to the identification signal is specified as a connection destination of connectors. The circuit state of the logic circuit is optimized on the basis of a result of specification of the sub substrate as the connection destination obtained by repeating the above-mentioned operation.
