A system configuration device provides system configuration information to a system unit. The device, for example a card, includes a circuit, circuit contacts, and a notch in one edge of thereof. The notch is configured to cooperate with a restraint when located in a card reading station for securing the card in the card reading station. A system configuration card reading station comprises a card receiver defining a slot for receiving the card, and a card reader including card reader contacts for contacting the circuit contacts on the card. The card reader contacts are located so as to contact the circuit contacts on the card when the card is received within the slot. The card receiver is configured to enable a restraint to engage the notch in the card for securing the card in the card reading station when the card is received within the slot. The restraint could be in the form, for example, of a padlock, a cable tie, or the like, to be operated manually, or it could be, for example a sprung or solenoid operated latch to be operated automatically.
