E1-RS485 Converter

View : 746
Type : E1-Serial converter
Description :

This interface converter is based on FPGA, providing one E1 interface and one RS485 serial interface, 1Channel RS485 transmission via E1 interface.

Overview

    This interface converter is based on FPGA, providing one E1 interface and one RS485 serial interface, 1Channel RS485 transmission via 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. Serial interface communication rate is up to 921.6KBPS.
