2.产 品 详 情 资 料：
ABB CM772F 3BDH000368R0001列出了标准EIA-232-D互连。并非表中列出的所有引脚都是每个应用程序所必需的。要正确解释信息，请记住EIA-232-D串行接口是为将终端连接到调制解调器而开发的。串行数据通过发送数据（TxD）线路离开发送设备，并通过接收数据（RxD）线路到达接收设备。当计算设备在没有调制解调器的情况下互连时，其中一个单元必须配置为终端（数据终端设备：DTE）ABB CM772F 3BDH000368R0001，另一个单元配置为调制解调器（数据电路终端设备：DCE）。由于计算机通常被配置为与终端一起工作，所以在大多数情况下，它们被配置为调制解调器。传输数据。待传输数据；从终端输入调制解调器。3 RxD接收数据。从接收线路解调的数据；从调制解调器到终端的输出。4发送RTS请求。当需要发送消息时，从终端向调制解调器输入。RTS关闭时，调制解调器载波保持关闭。当RTS打开时，调制解调器立即打开载波。ABB CM772F 3BDH000368R0001
lists the standard EIA-232-D interconnections. Not all pins listed in the table are necessary in every application. To interpret the information correctly, remember that the EIA-232-D serial interface was developed to connect a terminal to a modem. Serial data leaves the sending device on a Transmit Data (TxD) line and arrives at the receiving device on a Receive Data (RxD) line. When computing equipment is interconnected without modems, one of the units must be configured as a terminal (data terminal equipment: DTE) ABB CM772F 3BDH000368R0001and the other as a modem (data circuit-terminating equipment: DCE). Since computers are normally configured to work with terminals, they are said to be configured as a modem in most cases.Transmit Data. Data to be transmitted; input to modem from terminal. 3 RxD Receive Data. Data which is demodulated from the receive line; output from modem to terminal. 4 RTS Request To Send. Input to modem from terminal when required to transmit a message. With RTS off, the modem carrier remains off. When RTS is turned on, the modem immediately turns on the carrier.ABB CM772F 3BDH000368R0001
