2.4GHz active rfid reader long range with Arduino Mega 2560

But thanks for doing so now. It looks like that is wired up correctly?

i'm not sure,because take the circuit from another RS 485 interface project. Then, i tried to apply it in my project, but not working.

i also found another manual datasheet from the manufacturer. I have attach below related document. I think it might be helpful....
