RS232转422/485，可双隔离，高460.8Kbps，浪涌保护，2Km远传

一.  功能与特点1．    产品为光电隔离型RS232ßàRS422/485转换接口装置.可完成RS232ßàRS422数据通讯接口信号的转换,或用来实现RS232ßàRS485数据通讯接口信号的转换。2．    内部数据方向侦查控制电路使得RS232ßàRS485转换模式时不需要RS232侧提供流量控制信号.即可实现3线制的RS232接口与RS485接口的转换。（专利技术）3．    驱动能力强，传输距离远。RS422/485侧有防雷保护。4．    波特率从110bps到460.8Kbps自适应。5．    端子直流电源供电5V—36V宽电压范围。6．    亚当模块外壳，可卡轨式安装，方便机柜中使用。二.  性能指标电气标准 符合RS232,RS422/485(其中RS232为3线制即接收,发送和地)工作模式 异步全双工(RS422),异步半双工(RS485)自动适配传输速度 110BPS~460.8KBPS负载能力 RS422/485可驱动32个设备传输距离 RS422/485传送距离可达2Km(57.6Kbps速度下)隔离电压 1000V(3000V需订货)功   耗 小于1W 三.  接线端口说明RS232侧(按标准DB9母头出线)       Pin2   TxD（发）;   Pin3   RxD（收）;   Pin5 Gnd（地）RS422/485侧(10位端子)<table border= "1 " cellpadding= "0 " cellspacing= "0 "><tr><td style= "border: windowtext 0.5pt solid;
