RS232/422/485 Fiber Modem（Mini）

Type:FCP-DRQ Message

Description:RS232/422/485 Fiber Modem ，While providing 3*RS232 / 422/485 serial interface ， Serial port communication rate up 921.6KBPS

Product Description
               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 .
 
Functional Properties

◆  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
