RS-422 - видео

RS-422 also known as TIAEIA-422 is a technical standard originated by the Electronic Industries Alliance that specifies electrical characteristics of a digital signaling circuit. Differential signaling can transmit data at rates as high as 10 Mbits or may be sent on cables as long as 1500 meters. Some systems directly interconnect using RS-422 signals or RS-422 converters may be used to extend the range of RS-232 connections. The standard only defines signal levels other properties of a serial int...
