A technical standard that specifies electrical characteristics of a digital signaling circuit. Differential-mode signals can be sent at rates as high as 10 million bits per second, or may be sent on cables as long as 1,200 meters. Some systems directly interconnect using RS422 signals, or RS422 converters may be used to extend the range of RS232 connections. The standard only defines signal levels; other properties of a serial interface are set by other standards.
