E1-RS232/RS422/RS485 Converter

View : 491
Type : E1-Serial converter
Description :

This interface converter is based on FPGA, providing one E1 interface and one RS232 serial interface, 1Channel RS232/422/485 transmission via E1 interface.


    This interface converter is based on FPGA, providing 1Channel RS232/485/422 transmission on E1 interface. The product breaks through contradictions between traditional serial interface communication distance and communication rate, besides, it also can solve electromagnetic interference, ground ring interference and lightning damage. The device greatly improves reliability, security and confidentiality of data communication. It is widely used for various industrial control, process control and traffic control occasions, especially for Bank, and Power and other sectors and systems which have special requirements of electromagnetic interference environment. RS232/RS485/RS422 channel can transmit adaptable serial data asynchronously 512kbps baud rate.



Based on self -copyright  IC

Support 3 interfaces RS232,RS422,RS485, you can only use one, cannot use the three interfaces at the  same time
Can automatically detect and control RS-485 data flow without handshake signals to control the flow  direction of data
Have the ability to automatically detect the baud rate of serial port signal
Automatically test the reason of the device matt is that the device is power off, or E1 line is broken. And then  indicate on the LED.
Serial port interface lightning-protection reached IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV,    Impedance (2 Ohm),CM(Common Mode): 6KV, Impedance (2 Ohm) standard
Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
Serial channel can transmit adaptable serial data asynchronously 300 Kbps-921.6Kbps baud rate
