The choice is made by hard strapping to gnd for rs232 and vcc for rs 485.
4 8 out of 5 stars12. For using rs 485 in arduino a module called 5v max485 ttl to rs485 which is based on maxim max485 ic is needed as it allows serial communication over long distance of 1200 meters and it is bidirectional. Home explore schematic circuit module ttl to rs485. It is inconceivable that you would want to risk having this pin switchable.
