Mppt 450/100

Hello
I have installed an extra MPPT RS 450/100 in a daisy chain configeration using rj45 and bus terminators to another MPPT 450/200. However the new MPPT 450/100 does not show on device list in Cerbo GX. Tried everything but no success. Any ideas much appreciated

So ve.can dasychain like below?

Will the system find the “new extra” device if you use the old device’s RJ connection(just to troubleshoot, like faulty cheap wires)? Or it just disconnects from the list if running multiple at the same time?
How about if connected via BT? Can you get any connection to the new device even in solo mode?

Yes try swapping the cables it should find it, yes in BT you should see on local in victron connect assuming you are close to it.

I can access the device through BT oonly. I have a ve connect from GX to MPPT 450/200 and then daisy chain with rj45 to new MPPT 450/100. Is that correct or do i also need rj45 from GX through MPPT 1 and 2.

Terminator on the cerbo rj45 from cerbo to mppt1, rj45 from mppt1 to mppt2 then terminator on mppt2

How did you get on?
All ok or do you still have issues.
Let me know if i can help anyone.

All OK now - cable problem - used new rg45 and solved the problem. Many thanks to all you who contributed. Greatly appreciated
