E1 to 8*RS232/ RS485/ RS422 Protocol Converter

E1 to 8*RS232 interface converter, providing conversion between ITU-T G.703 standard E1 interface and 8 RS232 ports, offers safe and seamless connection of communication between different devices with different interfaces. Data interface mode is DCE, can connect with DTE or DCE device. RS232 channel can transmit RS232 asynchronous serial signal with auto-adapt baud rate of 0 to 115200.

Product Description

E1 to 8RS232 interface converter, providing conversion between ITUT G.703 standard E1 interface and RS232 ports, offers safe and seamless connection of communication between different devices with different interfaces. Data interface mode is DCE, can connect with DTE or DCE device. RS232 channel can transmit RS232 asynchronous serial signal with auto-adapt baud rate of 0 to 115200.


nBased on self copyright IC.

nSupport 3 wire RS232(TXD,RXD,GND) and supports flow control CD, DSR, CTS

nProvide 2 kinds loop back: E1 local loop, RS232 local loop 

nHave pseudo random code test function, can used as a 2M Protocol Analyzer
