So the green connection (which says rs485) that is next to the rs232 connection in the picture is the esp32 connection. If I use modbus with esphome, I have to connect the wires to it

the GREEN RS485 terminal use for 16 channel OUTPUT and 16 channel INPUT, it's fixed by KinCony ARM CPU. it not connected with ESP32's pin.
