Hi

You can use UDB based UART in PSoc Creator and use an external driver IC to convert the PSoC UART based RX, TX  and TX enable signals to RS485 signals through external driver.

Please find the attached image for connecting the PSoC 4 to RS485 through external driver.

You can also look at the following thread for more information.

How to connect RS485 device with PSoC4.

Thanks

Ganesh
