产品描述
本系列设备采用大规模FPGA设计,提供1个E1接口和1个RS232串行接口提供1路RS232在E1接口传输,该产品突破了传统串行接口通讯距离与通讯速率的矛盾,同时,也解决了电磁干扰、地环干扰和雷电破坏的难题,大大提高了数据通讯的可靠性、安全性和保密性,
可广泛用于各种工业控制、过程控制和交通控制等场合,特别适合银行、电力及对电磁干扰环境有特殊要求的部门和系统。串行口的通信速率可达256KBPS。
功能特点
◆ 基于自主知识产权的集成电路;
◆ 具备自动侦测串口信号波特率的能力;
◆ 自动检测设备收无光时是对端设备断电,或是E1断线,并在LED上指示;
◆ 串行口接口防雷达到IEC61000-4-5 (8/20μS) 差模:6KV 阻抗(2Ω);共模:6KV,阻抗(2Ω) 标准;
◆ E1口同时支持自适应的120Ω/平衡和75Ω/不平衡两种阻抗,不用再作设置;
◆ 机架式设备网管接口采用SNMP;
◆ 串行数通道可以传输异步从300-256Kbps波特率自适应的串口数据;
◆ 串行数据在E1中复用支持ITU-T R.111 跃变编码模式;
◆ 可以组成E1串口转换器(A)---E1光纤Modem(B)---光纤串口 Modem(C)的拓扑结构;
