Hello,

I have an old Multiplus 12/1600 with firmware version 1806133.VFF written on the chip (cf. picture attached), and I would like to connect a VE.Bus Smart Dongle to it.

When I plug the RJ45 cable on the dongle, the Multiplus stop working. I guess I’ll need to update the firmware, but I’m not sure if I need to buy the MK3 or MK2 Usb interface.
Could you confirm it is possible, and if so with which interface ?

Thanks,
Mat

Hello, I finally bought a MK2-USB adpater, working perfectly with VE Configure 3 !

Now, I am wondering if I should try to update the firmware 1806133.VFF to a newer version with VE Flash.
Could you advice which one I must use from here : Victron Energy - Victron Professional ?
I guess it will be in VE.Bus (Multis, Inverters and Quattros), but I don’t know which version (19 230V or 26 230V, Assitant or Non Assistant, etc)

Thanks,
Mat
