Understanding EIA-485 Part 2: Bias and Termination

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. Learn more at www.ccontrols.com.
