If you are using RS-485 this is a 2-wire connection, so one pair from the CAT-5 cable is sufficient (provided that the line is properly terminated and each device has pull-up/down resistors for "fail-safe" termination).
If you do not use the fail-safe termination, you must also use a third wire as a signal ground, so you will have to use one wire from the second pair.
