Connection Polytech US2000/US3000 - VenusGX (RJ45 - Ehternet Kabel?)

Hi,
i have two differing statements of my dealers. One ment that between US2000/3000 there simply comes a normal Ethernetcable/LAN, the other one ment its specially pinned, some are crossed over.

Can someone tell me what is correct, normal LAN cable or special cable? If so, can i cross an normal LAN cable to make it myself?


Regards

Norbert

Thanks a lot for your feedback. There are so many manuals - hard to navigate in the beginning....but its getting better and better.


Question to the community. Does it make sense/can i change the wiring of a standard LAN cable in order to build this B-Type cable.....

I guess i can remove all cabling except 3 wires.....

Hi @njordan

We strongly suggest to buy the factory cable, as 'home made' cables are a frequent source of hard to solve problems.

Not to say it cannot work, but I'd not risk it.

OK thanks, i the meantime i read this statement also in the manuals. just curious what is the problem, maybe people not knowing where to start counting.....
Again, i really only have to take into account 3 wires to make 100% sure and check via tester if its correct.
