FT-KZ485是一款经济型RS232-485转换器,实现RS232与485接口的互相转换。
性能指标:
★ 采用串口窃电技术,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RS485接口完全兼容;
安装使用:
FT-KZ485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-KZ485的公头(针座)端用于连接485网络。
各脚功能如下:1---T+(A) 2---T-(B)
A、B、脚分别与485总线相连
FT-KZ485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
外形尺寸:
FT-KZ485外形如下图所示:
61mm×33mm×17mm(未加端子)
