E1-31 Channel RS232/RS422/RS485 Convertet

Type:FCC-E1D31/R31/Q31 Message

Description:E1-31RS232/422/485 Converter , provides three interfaces Optional ， Used in pairs , Serial port rate up to14.4Kbps

Product Description
             This interface converter is based on FPGA, providing 31Channel 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 0Kbps-19200Kbps baud rate.
