VE Buss error Incompatible

I have 2 x Multiplus 3000 230/24 installed in parallel plus 1 x Multiplus ii 3000 120/24 as a stand-alone.

Connecting Cerbo Gx via VE bus to the 230v system works fine. Connecting Cerbo Gx via VE bus to the 120v system also works fine.

Problem arises when I plug both systems in a single VE bus - ie daisy chain between the multis and the Cerbo GX. Errors 3, 10, 17 and 25 - and all multis shut down.

All equipment 2024 build and latest firmware installed. Swapping all UTP cable had no effect.

Am I missing something?

You can only connect identical units together.

A workaround is to use a MK3 Interface to connect the 2nd VE.Bus system. BUT that 2nd system will NOT be controlled by DVCC or other signals it's only shown in the device list!

Great, that gives me clarification. I have both a Cerbo GX (with display) and a CCGX. I will run 2 separate networks - one to each display. Any thoughts on how I can connect the two displays so that my smartshunt will show on both? Use VE direct?
