    Hello,

    Those warnings tell you that you connected ports of different types together. Those rules are fixed in orcad Tools-->Design Rules Check --> ERC Matrix.
    There is a default matrix but you can set it up as you want.

    Regards,
    Franck.

    Just to add to that:

    Output connected to an input is usually OK.
    Input connected to an input is usually an error.
    Input connected to a bi-directional could be an error so you get a warning - you need to decide if it is OK.
    Input connected to power could be an error so you get a warning - again, you need to decide if it is OK.
    Passive connected to passive could be an error so you get a warning - you need to decide if it is OK.
