The RS232 port is of the 5-wire DTE type (TX, RX, RTS, CTS, GND) and has a terminal board for its connections.

The RS485 port is of the 2-wire type (TR+ and TR-) and has a terminal board for its connections.

There's no need to configure whether you are going to use the port RS232 or RS485. Just connect the wires to the corresponding terminals.

You must select if the analog inputs will be of the 0-10V or 4-20 mA type with the internal jumpers of the equipment. Disassemble carefully and place the jumpers as indicated in the figure. You will also have to configure the GRD from the configuration software indicating the type of inputs you are using.
