工业级高性能RS-232转RS-422接口转换器(FT-BC-205A)

产品概述
为了便于配有不同标准串行接口的计算机、外部设备或智能仪器之间进行远程数据通信,必须进行标准串行接口的相互转换。转换器兼容RS-232、RS-422标准,能够将单端的RS-232信号转换为平衡差分的RS-422信号。

转换器可将RS-232通信距离延长至1.2公里,无需外接电源采用独特的“RS-232电荷泵”驱动, 不需要靠初始化RS-232串口可得到电源, 内部带有零延时自动收发转换,独有的I/O电路自动控制数据流方向, 而不需任何握手信号 ( 如RTS、DTR等),从而保证了在RS-232全双工方式下编写的程序无需更改便可在RS-422方式下运行,确保适合现有的操作软件和接口硬件,转换器传送速率300-115.2Kbps。都可以应用于主控机之间、主控机与单片机或外设之间构成点到点、点到多点远程多机通信网络,实现多机应答通信. 广泛地应用于工业自动化控制系统、一卡通、门禁系统、消费系统、考勤系统、停车场系统、自助银行系统、公共汽车收费系统、公路收费站系统等等。
