This article provides information concerning the design of TIA/EIA-485 interface circuits. The document discusses the need for balanced transmission-line standards and gives an example for a process-control design. Line loading is discussed with subtopics of signal attenuation, fault protection and galvanic isolation. Finally, setting up and measuring using eye patterns is documented. Eye patterns are used to measure the effects of signal distortion, noise, signal attenuation, and the resultant intersymbol interference in a data transmission system.
