Multiplus and DMC + Cerbo does not work - any advice?

I have a working Multiplus 12/3000/120 system, which includes a Cerbo GX.

When I try to also connect a 200/200 Digital Multi Control Panel GX, it simply does not work. The MP will not turn on. If I disconnect the Cerbo, then the DMC works. With both connected, the MP simply does not turn on, no lights, nothing.

FWIW, I've tried this with two DMC units; I assumed the first was bad.


Others have had this problem: https://community.victronenergy.com/questions/86659/multiplus-digital-multicontrol-and-cerbo.html but that post did not have any solutions. Are there any? Are they supposed to work together? That post indicates they should. Thanks!

Did you read these notes? Multi has to be "ON".

Yes, I did understand that, thanks.

(I’m beginning to suspect bad cables. Will probably just order new ones.)

Well, I've now tried brand new cables and still have the same problem. For this reason and other reasons, I am beginning to suspect a bad Cerbo unit. I will start another thread.
