The invention relates to a control system comprising a motherboard (1) having at least two auxiliary card connectors (2A, 2B, 2C) and a control bus (6) on which control addresses and control data are transferred. Auxiliary cards (3A, 3B, 3C) are connected to the auxiliary card connectors of the motherboard, the auxiliary cards being essentially identical but having different control addresses for selective controlling through the control bus (6). In the present invention the control addresses of the auxiliary cards are card location-specific and provided (8A, 8B, 8C) on the motherboard by wiring or switches or in some other corresponding manner. When an auxiliary card is inserted in an auxiliary card connector of the motherboard, the auxiliary card always obtains the correct address from the motherboard through the connector. |
