GPS2 Sensor versus Multiplex Update

  • Hello, I used a Powerbox GPS on a MPX Rx and made a update to 1.35 ( MPX) to have all the addresses on MPX.

    Now, I want to use the same GPS on a I Gyro, but I have the message " no sensor" .

    I tryed to update the GPS to the last Powerbox version, but the terminal says " no Powerbox device connected "

    What can I do ?

    Thanks a lot for help.
