    Hello Roberto,

    That is expected behavior. It means the senc or srec file you programmed in was already sealed. You will need to unseal and enter full access keys.

    Thanks Kang

    My normal procedure is 

    Send 0041 (reset)

    Send 0021 enable the impedance track algorithm

    Review information

    Finally send 0020 to seal

    If I unseal and send a full access keys (turn off flag "FAS" and "SS”)

    I cannot return to the normal procedure, because automatically the packet enter to seal when I send 0041(reset)

    That’s is expected behavior, (one time the seal code (0020) is send, the packet enter to seal when I send 0041)
