I have multiple VE Bus products that all connect using VE Bus cabling.
2 x Multiplus (paralleled)
1 x bms
1 x cerbo
1x ac detect
1 x Mtiplus control panel
My question is: Is there an order to connecting the VE bus rj45 connectors? Or can I connect from one unit (in) and (out) to the next device creating a ri g network.
Is VE bus use a backbone network protocol and communicates with everything at the same time or do I have to connect each item in a certain sequence?
Thanks in advance

I guess with "BMS" you mean a VE.Bus BMS.
There are many example diagrams in the manual.

Hi Matthias, thanks for you answer. While the bms manual shows many configurations I still cannot find an answer to the question regarding VE BUS.
Is it a network based protocol and does it matter which device is connected as long as all devices are connected on a ring (in and out) ?
You can't just plug in the RJ45 as you want.
Between your two MultiPlus' you just need one RJ45 cable from one unit to the other.
OK so if I follow the manual can you please explain where I now plug in my Cerbo unit?
Many thanks
Graham
A GX device (Color Control GX in the picture) have t be connected to the MultiPlus/Quattro.
I have spoken to a Victron dealer and this is how you connect multiple Multiplus' withitium bms and a cerbo.
