    Description


    E1 to 1* RS232/ RS485/ RS422 interface converter, providing conversion between ITU-T G.703 standard E1 interface and 1* RS232/ RS485/ RS422 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/ RS485/ RS422 channel can transmit RS232 asynchronous serial signal with auto-adapt baud rate of 0 to 115200.

    Features


    ■ Based on self copyright IC.

    ■ Support 3 wire interface: RS232, RS485, RS422, the user can choose any one of 3 wire interface

    ■ Supports 3-wire RS232 (TXD, RXD, GND)

    ■ Provide 2 kinds loop backE1 local loop, RS232/ RS485/ RS422 local loop 

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

    ■ Support both 120Ω/balance and 75Ω/unbalance impedance

    ■ RS232/ RS485/ RS422 support hot plug, can connect with DTE or DCE 

    ■ RS232/ RS485/ RS422 channel can transmit RS232 asynchronous serial signal with auto-adapt baud rate of 0 to 115200
