he Telecommunications Industry Association (TIA) and Electronic Industries Alliance (EIA) standard for RS-485 communication was established two decades ago and has been widely adopted for a variety of applications. RS-485 is the ideal standard for reliable communication over long distances of 1000 meters because of the twisted pair structure used to send a differential signal.

Isolated RS-485 Reference Design
PDF, 80 Kb, File published: Oct 28, 2009
This design note presents the reference designs of isolated RS-485 nodes, using bus voltages of 3.3 V and 5 V. Various transceivers are used to satisfy the requirements for low, medium, and high data rates, as well as to accommodate the need for half- and full-duplex operation.
