HONEYWELL 620-0085傳輸數(shù)據(jù)(A)。待傳輸數(shù)據(jù);從DTE到DCE的輸出。3 RxD_A接收數(shù)據(jù)(A)。從接收線路解調(diào)的數(shù)據(jù);從DCE到DTE的輸入。4 RTS_A發(fā)送請求(A)。當(dāng)需要傳輸消息時,從DTE到DCE的輸出。5 CTS_A清除發(fā)送(A)。從DCE向DTE的輸入,指示消息傳輸可以開始。6 DSR_A數(shù)據(jù)集就緒(A)。從DCE向DTE輸入,指示DCE已準(zhǔn)備好發(fā)送或接收數(shù)據(jù)。在DCE配置中,始終為true。7 SIG GND信號接地。所有信號的公共回路。8 DCD_ A數(shù)據(jù)載波檢測(A)。HONEYWELL 620-0085從DCE到DTE的接收線信號檢測器輸出,指示有效數(shù)據(jù)正在RxD線上傳輸?shù)紻TE。接收信號單元定時DCE(B)。對輸入數(shù)據(jù)計時的控制信號。10 DCD_ B數(shù)據(jù)載波檢測(B)。從DCE到DTE的接收線信號檢測器輸出,指示有效數(shù)據(jù)正在RxD線上傳輸?shù)紻TE。11 TxCO_B發(fā)送信號單元定時DTE(B)。時鐘輸出數(shù)據(jù)的控制信號。12 TxC_ B發(fā)射信號單元定時DCE(B)。為輸入數(shù)據(jù)計時的控制信號HONEYWELL 620-0085
Transmit Data (A). Data to be transmitted; output from DTE to DCE. 3 RxD_A Receive Data (A). Data which is demodulated from the receive line; input from DCE to DTE.HONEYWELL 620-00854 RTS_A Request to Send (A). Output from DTE to DCE when required to transmit a message. 5 CTS_A Clear to Send (A). Input to DTE from DCE to indicate that message transmission can begin. 6 DSR_A Data Set Ready (A). Input to DTE from DCE to indicate that the DCE is ready to send or receive data. In DCE configuration, always true. 7 SIG GND Signal Ground. Common return line for all signals. 8 DCD_A Data Carrier Detect (A). Receive line signal detector output from DCE to DTE to indicate that valid data is being transferred to the DTE on the RxD line.Receive Signal Element Timing—DCE (B). Control signal that clocks input data. 10 DCD_B Data Carrier Detect (B). HONEYWELL 620-0085Receive line signal detector output from DCE to DTE to indicate that valid data is being transferred to the DTE on the RxD line. 11 TxCO_B Transmit Signal Element Timing—DTE (B). Control signal that clocks output data. 12 TxC_B Transmit Signal Element Timing—DCE (B). Control signal that clocks input data
