    Default serial protocol A error and IQ3 firmware upgrade problem


    I have 2 IQ3, and one was sent to Racepak to upgrade in the middle of last year.

    The other one has not be upgraded, and I tried to make different setting through DataLink.

    It was connected and recognized, but when I clicked SEND Configuration, I got error Message Log like attached file.

    1. What is the mean "CCP ERROR"?

    I tried firmware upgrade(IQ3D_v27.hex) both of them, but failed, because of "cannot communicate with the IQ3".

    They was connected to Datalink and recognized.

    2. What is the problem and how can I know my IQ3s' version?

    Anyone help me!
