digital isolator and RS422

[kunal5959]

I have to isolate a Microcontroller atmega128 having serial interface MAX1481 from another Atmega circuit using ADum4402 full duplex isolator. Can anyone guide me in designing the schematic for such an isolation. The schematic below gives a brief idea showing atmega128 connected via RXD and txd to MAX1481 (rs422 transciever) and the chip adum4402 digi isolator is also present..Please guide me with the circuit design so the signals sent or received by Microcontroller is exac replica of signal on other side of adum4402.

The isolator must be connected on the logic side of the RS422 transceiver.

Yes i understand but what about the terminating resisitors or capacitors?
