    Note: If you select this option, when you are connecting devices with wires, and the system of the wire does not match the system of the electrical connector on the device, you cannot add the wire.
    be prompted before connecting to an existing system select Prompt for user input. If you accept a connection between dissimilar systems, you have 2 options:
    • You can establish a valid connection by changing the part’s system to match the existing system.
    • You can ignore the system and create an invalid connection.
    Note: If you select this option, when you are connecting devices with wires, and the system of the wire does not match the system of the electrical connector on the device, you are prompted to accept the change of the system of the connector. If you do not accept the change, you cannot add the wire. The system of the device, which only determines how the device is displayed, is not affected.

The system of the connector on the device is automatically changed. The system of the device, which only determines how the device is displayed, is not affected.
