question

I am using MultiPlus-II controlled by Cerbo GX. I would like to try the "Dynamic current limiter" and "Weak AC" settings as my generator does not produce very stable voltage (it fluctuates sharply in the 220–230V range). These settings do not seem to be available via the GX LAN Remote Console so I would like to leverage VEConfigure on-site (I do not want to use any remote tools).

I have checked the requirements for wired connection: https://www.victronenergy.com/media/pg/VEConfigure_Manual/en/introduction-and-requirements.html

It appears that I need an MK3-USB dongle.

1. Cerbo GX and MultiPlus-II have two VE.Bus sockets each. They are connected together using one, so there is one left on each side. Should I plug the dongle into the GX or into the inverter directly?
   
   
2. Cannot the GX USB ports be used instead, without an MK3-USB dongle? Does not Cerbo GX work as a dongle itself?

Thanks in advance!
