Hi Admin
Done connected gnd on the logic and pin 7 on the inverter, but always CRC error. Change the cable, put the logic near the inverter and tried on port-1 and 2 ..... But nothing change. Always CRC error.
Now I want to try with a usb to 485 gateway and test the connection with a pc.
If someone has another solution it is welcome.
Thanks for the help.
Best regards Cristian
