    Hi i like to use the RXTX gpio pins in the Raspberry Pi but i need to lower a gpio pin or high before read or write in the 485.

    I can do both things separately by setting the pin high or low by default and dont changing him.

    Is there a way to low or high the Gpio pin.

    Thanks.

    Hi Javier. I'm doing that too. Do you have any additional information? Why don't use the Ethernet port with Modbus TCP?
