By your question, you have not looked at the data sheet for the ADM485.

Here is a link, http://www.analog.com/static/imported-files/data_sheets/ADM485.pdf

Look at figure 30 on page 12.

Also, http://www.lammertbies.nl/comm/info/RS-485.html

Google is your friend.

In the time it took you to wait for my response, you would have had your answer and would have been on your way to solving your question on your own.

You will be able to turn in this homework assignment with the knowledge your professor wanted you to learn.

good luck
