rs422

RS-422, also known as TIA/EIA-422, is a technical standard originated by the Electronic Industries Alliance that specifies electrical characteristics of a digital signaling circuit. It was intended to replace the older RS-232C standard with a standard that offered much higher speed, better immunity from noise, and longer cable lengths

EIA-422(過去稱為RS-422)是一系列的規定採用4線,全雙工,差分傳輸,多點通訊的資料傳輸協定。它採用平衡傳輸採用單向/非可逆,有使能端或沒有使能端的傳輸線。和RS-485不同的是EIA-422不允許出現多個傳送端而只能有多個接受端。

RS422 was introduced to enable higher data rates to be transferred over serial data lines than was possible with RS232. RS422 is able to provide data rates of up to 10 Mbps at distances up to 50 feet (15.24 metres). However using reduced data rates, RS422 is able

RS422 allows the direct connection of intelligent devices, without the need of modems. Furthermore, where the RS232 line driver is only designed to serve one receiver, a RS422 line driver can serve upto ten receivers in parallel. This allows one central control unit
