I am looking for the pinout of RJ45 UTP Cable

When I use an ordinary LAN cable to connect VE-Bus from the MPII Inverter to Cerbo-GX my system shows an error on the MPII-3000-35-48 and stops charging from MPPT250-70.
So what is the pinout of the VE-Bus cables please?

It's just a standard straight-through LAN patch cable (NOT a crossover cable.) So long as the colours are same at each end it should work; these are normally wired as per T568B though.

Problem is probably low quality cables, or lower speed lan cables which do not have all pins wired.
