4 Channels Serial Data RS232/422/485 Fiber Optic Modem

View : 250
Type : Serial Optical Fiber Modem
Description :

This series of devices use FPGA design, providing 4 channels serial ports, each port supports RS232/422/485 three business interfaces.

Overview

This series of devices use FPGA design, providing 4 channels serial ports, each port supports RS232 / 422/485 three business interfaces. The device is the best choice for connecting a remote terminal unit (RTU) to a host (HOST) or a distributed data acquisition system (SCADA) controller with high-cost performance. Effective transmission distance up to 0-120KM, serial port communication speeds up to 0-115.2KBPS.

Adopting optical fiber as a transmission medium can completely avoid the threats from harsh environments like lightning, surges, and electromagnetic interference to communications equipment, and it also eliminates the cost of lighting surge protection devices for using copper as a transmission medium.

Features

Provide 4 channels serial ports, each serial port also provides three serial ports RS232/422/485 (interface type can be set by DIP switch) to start the service on-site conveniently ;

It can detect, and control RS-485 data flow automatically, with no need handshake signal to control data flow;

With the ability to detect serial signal baud rate automatically;

When there is no optic signal. it can detect automatically whether the opposite end device is powered off, or the fiber is disconnected and indicates on the LED;

Rack-type device provides network management SNMP;

Serial channel can transmit asynchronously, baud rate from 300-115.2Kbps adaptive serial data;

Serial interface lightning protection to IEC61000-4-5 (10/700μS).Differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω);
