Carlo Gavazzi Three phase CT version with RS485

Hi All ,

I am installing the Carlo Gavazzi three phase energy meter with my CCGX. the model number of the meter is EM24-DIN.AV5.3.D.O2.X This is my first Victron install AND so far I have been able to detect the hardware from the image below.

The objective is to monitor import and export from the GRID. I am unable to detect the Carlo Gavazzi energy meter however. I have an existing usb to RS485 in the image below.


It has data+ and data - but no ground. Can anyone confirm if this rs485 adapter compatibility with the ccgx or do I need to get the one sold by Victron. has there been any success with other rs485 adapters? any other configurations necessary for meter detection? Thanks I appreciate any help.

You should use the cable recommended by Victron.
Also you have to switch the switch at the EM24 from locked to 1 or 2.
