串口至RS422转换器[FT-KZ422]

串口至RS422转换器[FT-KZ422]

北亿纤通专业研发生产的 FT-KZ422是一款经济型RS232-422转换器,用来实现RS232与422接口的互相转换。
性能指标:

★ 采用独特串口窃电技术,无须外部供电;
★ 数据传输速率自动适应,速率300-115.2kbps;
★ 最远传输距离达1200米;
★ 转换传输TXD、RXD、GND三线信号
★ 接口转换完全透明,一切工作自动完成,适应所有软件;
★ 标准RS232串口皆适用,尤其单片机串口也能用;
★ 独有外部调节电阻,适应任意数量节点(<32);
★ 与RS422接口完全兼容;

安装使用:

FT-KZ422的外型为DB9-DB9:
母头为DCE(孔座)端直接插入9针设备。
各脚功能如下:2---TXD 3---RXD 5---GND 
如果串口为25针插座,需要使用DB25-DB9转接线,把25针的串口转换为9针串口。
FT-KZ422的公头(针座)端用于连接422网络。
1---TX+ 2---TX- 3---RX+ 4---RX-
1、2、3、4脚分别与422总线相连(正接正 负接负)。
FT-KZ422配有一块扩展端子,使用更方便。

应用领域:

适用于各种RS232至RS485接口之间的转换,RS232接口可以是PC机、终端设备、控制设备、
仪表采集、多串口设备、单片机的串行接口等
