31 Channel RS232/422/485 Fiber Modem

Type:FCP-R31/U31/D31 Message

Description:31 Channel RS232/422/485 Fiber Modem ，Can be asynchronous transmission from serial data 0-115200 baud rate adaptive

Product Description
              31RS232/485/422 Fiber Modem provides 31Channel RS232/485/422 transmission on fiber. 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-19.2Kbps baud rate.
