E1 to RS232/RS485/RS422

E1 to RS232/RS485/RS422 converter provides conversion between ITU-T G.703 standard E1 interface and RS232/RS485/RS422 port and provides 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/RS485/RS422 asynchronous serial signal with auto-adapt baud rate of 0 to 115200.

Features

1. Based on self copyright IC
2. Supports 3 wire RS232 (TXD, RXD, GND) and supports flow control CD, DSR, CTS
3. Provides 2 kinds loop back：E1 local loop, RS232/RS485/RS422 local loop
4. Having pseudo random code test function, can used as a 2M Protocol Analyzer
5. Supports both 120Ω/balance and 75Ω/unbalance impedance
6. RS232/RS485/RS422 supports hot plug, can connect with DTE or DCE
7. RS232/RS485/RS422 channel can transmit RS232/RS485/RS422 asynchronous serial signal with auto-adapt baud rate of 0 to 115200
