I have installed energy meter Carlo Gavazzi EM530 and installed the program UCS-7 (Carlo Gavazzi) on my PC for presentation of measurement data. I want to see the data from the energy meter on my PC before I connect the EM 530 to the Cerbo GX. I have used a 15 m RS485 cable from the meter to the Victron USB RS485 converter which connects to my PC.
The connection has been checked several times
Problem: I have no contact with the meter when I use ModbusRTU and search for the energy meter from USC-7.
The Victron USB RS485 converter only shows a constant red light and no RX or TX signals.
What is wrong?
