Conection to Multiplus with MK3-USB not possibile

Hey Guys,


I can´t connect to my Multiplus 12/1200/50 I followed the instruction of the victron videoI found here, https://www.youtube.com/watch?v=6lH3mF2cVaY&t=6s I tried using both a mac and a win 10 laptop, both with the same result, that the Victron connect or VEConfig app won´t go beyond the point “fetching data from VE-Bus” and then times out. I double checked the drivers in windows and COM port 7 uses FTDI driveres I also tried the VE Config app with “auto detect port” and manualy selected both com3 and COM7” with the same result that it can´t connect. If I go to force connect it times out as well.

If I use a Color Control on the VE-Bus port the Multiplus is recognized but I can´t really change any setting or setup an ECC.


From the Color Control I see the following firmware details of the Multiplus.


Productcode:2662

Fimrware 416

Device Instanz: 257

VE.BUS Version: 2662416

MK2 Device MK3

MK2 version 1170207


Any help on how to properly connect would be very much appreciated!

Thanks for your support.

Make sure you disable the firewall(s), I had problems with that.

Not sure if it will solve it but something to be aware of.


Good luck,

Jordi

the firewall does not apply to serial connection and since I don´t use vrm I don´t see how this would make any difference, anyway I tryed it and also with deavtivated firewall same situation, both on windows and mac,

try this and use your android phone or tablet .

purchase a cable that converts your phones charge point to a usb Female cable that the MK3 can plug into

install the latest Victron connect app to the phone or tablet

connect the mk3 to the phone and directly to your multiplus

open the victron connect app on the phone and you should see the multiplus then select it and go from there.

once you get a connection upgrade the firmware of the multiplus.
