Please let me know where i can get schematic for below requirement.
i wanna create simple schematic where i can take a TTL input and convert in he form RS232/RS485 (both)
example. I wanna read data from arduino board. and interface with RS485 and RS232 communication modules. i know we can use serial monitor to view data they are in TTL format.SO i wanna create ttl to rs232 , rs232 to rs 485 or ttl to rs485 devices for interface with module so that it reside on main PCB. But i need circuit where i can take data in TTL format and convert into both format. INPUT:ttl format output1:RS232 output2:RS485
