Adding VE.Bus Dongle using a splitter

I have a MultiPlus-II 12/3000/120 with a Digital Multi Control 200/200A. The DMC is easy to access, but the MultiPlus is difficult to reach. Can I install a VE.Bus splitter behind the DMC so the VE.Bus Smart Dongle and the DMC both connect there, or must the dongle be connected directly at the MultiPlus?

You can use the two like that.

Thank you. A follow-up question: If I use the official Victron RJ45 Splitter behind my Digital Multi Control, I will need to connect the existing VE.Bus cable to the splitter’s male plug with an RJ45 female/female coupler. Is a standard straight-through RJ45 coupler acceptable?

The straight patch cable works to the BT ve bus dongle.
