Modbus TCP Epever XTRA with USR-N510

Good morning community,

I am trying to get a reading from an Epever xtra solar charge controller with rs485 on my home computer network,
I have connected the device to the USR-N510 in modbus TCP mode, but I only get time out errors in the connection.

Configuration Epever in USR
Baund rate: 115200
Data bits: 8
Parity: none
Stop bit: 1
Flow ctrl: none
RTFC: ON

Configuration Socket:
Parking: Modbus TCP
Suported: 8 KICK
Port: 502

Errores:
Time out

Hello community,

Apparently there is a configuration error in cables A, B and GND, the original device (Epever xtra) has A and B inverted.

Greetings to all.
