Rs485 To Ttl Circuit. Schematic circuit module ttl to rs485. 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.

I have these following questions related to this.
It is inconceivable that you would want to risk having this pin switchable. However i cannot be sure about rs485 transceiver and its circuit. Rs485 to uart convension circuit i need to send data from one pic to another pic by using rs485. See diagram on p.
