Hi, I’m sorry, but you need to use an original cable.


we have lost a crazy amount of time in r&d trying to help people with knock-off and or just other type cables. Sometimes the tx is not working, but only rx and so forth; causing the craziest errors; which normal support teams can’t handle so it ends up in r&d to rule out a possible bug; all a major waste of time.

Of course I do understand the normal cables are costly; but there really is no other (supported) solution. Merry christmas!, Matthijs
