E1-RS232/RS422/RS485 Convertet

Type:FCC-E1D1/R1/Q1 Message

Description:E1-RS232/422/485 Converter provides three interfaces Used in pairs Serial port rate up to 512Kbps

Product Description
             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.
 
Functional Properties
Ø based on self -copyright IC
Ø   Support 3 interfaces RS232RS422RS485 you can only use one cannot use the three interfaces at the  same time
Ø   Can automatically detect and control RS-485 data flow without handshake signals to control the flow  direction of data
Ø   Have the ability to automatically detect the baud rate of serial port signal
Ø   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
Ø   Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
Ø   Support SNMP Network Management
Ø   Serial channel can transmit adaptable serial data asynchronously 300 Kbps-921.6Kbps baud rate
Ø   Serial data multiplexing in E1 support ITU-T R.111 jumping coding mode

Ø   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
