Does anyone know if I can connect this energy meter and usb to rs485 cable with the cerbo gx?

If you are trying to use it for a grid measurement or a PV inverter then you are probably out of luck unless it happens to appear exactly the same on Modbus as one of the Carlo Gavazzi or ABB meters: https://www.victronenergy.com/upload/documents/Datasheet-Energy-Meters-Selection-Guide-EN.pdf
Hi @rgear13
As Dean mentions you'd either have to hope the modbus output is the same as those two supported meters. Or if you're good at python you could probably analyse that meters modbus output and then create custom driver to implement into venus os/gx device.
It shouldnt be too difficult you could copy the python scripts for the existing supported carlo and ABB meters:
They can be found in the below paths of the venus os/gx device.
/opt/victronenergy/dbus-modbus-client/abb.py
/opt/victronenergy/dbus-modbus-client/carlo_gavazzi.py
And then you'd need to add the new version say you call it newMeter.py to the dbus-modbus-client.py document by adding
import newMeter
In regards to the cable it looks to be the correct chipset but I'm not 100% sure what other criteria is required regarding cables.
However it looks similar to this guys cable who had to tweak something in his:

EDIT: If you go the route of making custom python script you may have more success moving the question to Modifications section of the forum.
