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RS485串行接口提供1路RS485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。

应用方案说明一、
设备可以通过一条E1通道传输1路串行数据，串行数据在E1中采用ITU-T R.111跃变编码模式，波特率可以为300-512K.

应用方案说明二
A点串行数据接口通过一条E1通道传输B点为E1光纤ＭodemC点为串口光纤Modem串行数据在通道中采用ITU-T R.111跃变编码模式，波特率可以为512KBPS.
