Split ve.bus from Multiplus

Is it possible to use a Rj45 splitter in the system?

I have a Multiplus 3000-12-120.
It have 2 ve.bus contacts.
One I use to the cerbon gx (ve.bus 1) and the other to the multi control (ve.bus 2).

I also use a mk3-usb but I have to disconnect the multi control cable and connect the mk3 everytime.

Is it possible to use a Rj45 splitter so I can connect both the multi control ond the mk3 to the ve.bus 2 contact?

I’m not certain that leaving an MK3 continuously connected wouldn’t cause issues (I seem to remember the Cerbo doesn’t like it), but as a direct answer to the question it is possible so long as the right kind of splitter is used: RJ45-splitter - Victron Energy

Yes you are right, cerbo does not like that!
