How to interface PIC to RS485? Is it possible to connect the MAX RS485 to the UART.....if so how do i proceed with? Do i need to introduce some protocols. As i am new to this.
Basically i am trying to send command bytes over distances greater than 100mtrs with speed not an issue. With multiple end devices connect to it receives the command at the same time.
Basically i am designing a hub with i/p's(max of 4 inputs) from actuators and slaves connected to the hub(output). When an acutator input is received process it and sent a common command to all the salves connected to the ouput....based on the command each slave will do the necessary.

remotes(slaves) will only receive.
