I am setting up a system with, Multiplus 800, SmartLifepo4, VE Bus BMS, CANVu GX with extender kit & a Digital control panel for the Multiplus. My problem is that the Multiplus only have one RJ45 socket & i need to connect the cable from the VE Bus BMS to that port. So that leave me with the RJ45 from the Can Vu GX Extender, where do i connect that?
