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 back：E1 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
