RS232 fiber modem
This device is based on FPGA, which supports asynchronous RS-232 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 multimode fiber, effective communication distance is up to 4KM,
while using ordinary singlemode 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 .
Features
Based on self -copyright IC
Have the ability to automatically detect the baud rate of serial port signal
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
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
Support SNMP Network Management
Serial channel can transmit adaptable serial data asynchronously 300-921.6Kbps baud rate
