How to use a ttl to rs485 with the getter node

[VALERYRAMIREZ]

Hi, how are you?.

I'm here to ask if there is any way to use a ttl to rs485 converter from a raspberry pi 4 using any of the modbus nodes you provide. I know the OS is managing the serial port but I don't know what to do with the DE and RE signals to enable write or read from the MAX485, I've seen several examples around there on how to use it but all of them are using python or any other language code instead of node red.

Thanks in advance for the help.
