  • Hello Johnny,

    I am sorry, I am not able to understand your question clearly.

    Would you like to probe the TXn, INP and INN signals on the board?

    If that is the case, you can check the TXn signals on the J4 connector.

    For the INP and INN signal, you can either use the L1 or J4 connector.

    Please refer to the AFE4404EVM schematics in section 11.3 of the user guide document.
