MultiPlus & Cerbo GX & Mk3 to USB

I have a MultiPlus, Cerbo GX, BM712, Mk3 to USB, and a VE Bus smart dongle. I used the smart dongle and usb to mk 3 before I purchased the Cerbo GX

I have everything plugged in and running ok, but was wondering if its ok to plug the Mk3 to USB in to the 2nd VE Bus port on the Cerbo GX. And I presume I cant plug the VE Bus smart dongle into the Cerbo GX as it only has two VE Bus ports. Is that correct.

But if you want to update the MultiPlus firmware, connect the MK3-USB directly to the inverter and disconnect all other VE.Bus devices from it.
