在串行通信時,要求通信雙方都采用一個標準接口,使不同的設備可以方便地連接起來進行通信。在設計通信接口時,一般都采用標準接口以提高其通用性。本系統(tǒng)中,上、下位機進行通信首先面臨的問題就是通信標準的選擇問題。
1、RS-232C接口標準
RS-232C接口標準(全稱EIA-RS-232C標準)是在1969年由美國電子工業(yè)聯(lián)合會(EIA,ElectronicIndustrialAssociate-RecommendedStandard-232C)與Bell公司、調制解調器廠家及計算機終端生產廠家共同開發(fā)的用于串行接口的通信協(xié)議。它最初是為遠程通信連接數(shù)據(jù)終端設備DTE(DataTerminalEquipment)和數(shù)據(jù)通信設備DCE(DataCommunicationEquipment)而制定的[46]。雖然這個標準的制定沒有考慮計算機系統(tǒng)的應用要求,但是廣泛的用于計算機與終端或外設之間的連接。
