Video: Understanding EIA-485: Connectors, Grounding and Protection
July 2013 – The Understanding EIA-485 Video Series discusses the popular EIA-485 technology - commonly called RS-485 - used for interconnecting network devices.
This video discusses the importance of cabling and repeaters. Cables attenuate and distort signal, so cable selection depends on data rate, encoding, distance. Repeaters that use the data link protocol are more reliable than basic EIA-485 repeaters.
