Video: Understanding EIA-485: Bias and Termination
May 2013 – The Understanding EIA-485 Video Series discusses the popular EIA-485 technology - commonly called RS-485 - used for interconnecting network devices.
In this video we discuss two important issues with multipoint systems - termination and bias. Terminating a data cable properly reduces reflections that could cause data errors. Correct bias assures that each device on the bus properly interfaces with the bus for reliable operation.
