Hello,

Thank for the factory reset. I succeed to do it. The CPU behave well now (I mean no error on a port which was never connected, used).

The cables have been labelled from the beginning. When I reverse the round ports, or when I reverse the RJ ports, I have always the same result: the right rear head is not working in parking mode, it detects my laser tester but it doesn't emit. It makes sense with the parking mode which is not working. I will dismount this head and send it for guarantee exchange.

Thank you very much for your support! The mess was from the CPU which was needing a factory reset.
