    overview

     

        This device is based on FPGA, which supports asynchronous RS-232/422/485 communication interface Fiber Modem. The device is the best choice of connecting to the remote terminal unit (RTU) to a host (HOST) or a distributed data acquisition system (SCADA) controllers, with very high performance price ratio. Using ordinary multi-mode fiber, effective communication distance is up to 4KM, while using ordinary single-mode fiber, effective communication distance up to more than 40KM. Serial port communication rate is up to 921.6KBPS. As a result of the fiber as a transmission medium, you can completely avoid the threat to communication device under the adverse environment, such as lightning, surges and electromagnetic interference, at the same time it saves investments of the original lightning surge protection devices that using copper .

     

    feat

    ◆ 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 RS485 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 when the device is power off or Fiber optic line is broken. And then indicate on the LED
    ◆ Support SNMP Network Management for chassis system
    ◆ Serial channel can transmit adaptable serial data asynchronously 300 Kbps-921.6Kbps baud rate 
    ◆ 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.
