Hi, I have a problem with the connection between my Helix Rack and the controller. When I use the original Cat-5 cable, everything works fine. But I tried using another one — it's also a Cat-5e cable — and when I connect it, the controller doesn't work. It only lights up, but doesn’t respond, and the rack displays a message saying “Controller must be updated.” It never updates… I’ve tried everything, I swear. Lot od cables and lenghts… What’s interesting is that I also tested it with an old Cat-5 cable I made myself — and if I connect it one way, it works, but if I flip the connectors, I get the same problem and it doesn’t work. I'm looking for help from anyone who has dealt with the same issue. Thanks!
