Multiplus 12/1600/70 with MK3 - How to use multiple devices with a single VE.bus port?

Hi all,

I want to use a raspberry as the venus device. I want to connect my MPPT 100-50, BMV712 with the VE-Bus and my Multiplus with the MK3 Interface.

But I want to use the normal remote control the digital multicontrol 200/200a too. Is there a way to connect all 3 devices (multiplus, multicontrol and MK3) at the same time ? As far as I know all three divices have only one RJ45 connector.

Thanks for help

Hoagie

Hi

Yes you should be able to as it is a VE bus device if this connects to the Mulitplus then the mulitplus connects to the Raspi via the Mk USB device is should pick it up.

Hi @Joagie,

It is possible to use a straight through RJ45 splitter to increase the VE.Bus ports available on these smaller units (and the other devices that only have 1 VE.Bus port).

Hi, I would like to do this with some Multiplus 12|800|35 units. Can you elaborate on the straight through RJ45 splitter? Which one is this and/or what is the schematic? I have tried some Lindy 1 into 2 splitters but they do not work.

Hi @esterill,

The recommended known working part is Victron Part number - ASS030065510 - RJ45-splitter 1xRJ45 male/15cm cable/2xRJ45 female

Your Victron dealer should be able to supply it.
